PERIOD OF TECHNICAL IMPROVEMENTS AND INNOVATIONS (1987-1997)
From the beginning Badotherm paid a lot of attention to quality. It is in the DNA of the company. Our slogan ‘never compromise on quality’ shows our clear vision on this topic. However, this means not only focusing on product quality. In the early nineties, we recognized the value of the ISO 9001 QMS standard. To get ISO certified it is required to identify and describe your company processes and manage and control them with business metrics. A quality management system standard is all about an improved level of quality and results for the entire organization. For every process, and every product. In the end, the ultimate objective of quality management systems is customer satisfaction. Because only consistent and efficient produced high quality products and services that meet or exceed customer expectations, will result in excellent customer satisfaction.
On the technical side, we had several breakthroughs in this decade. In 1992, Badotherm was the first diaphragm seal supplier in the world to make a gold plated diaphragm seal with a layer thickness of 40 mµ. It was specially engineered for one of the largest refineries in the world (located in The Netherlands). This diaphragm seal with gold coating was used for hydrogen applications with process temperatures up to 400° Celsius. For more information about this solution, we refer to our gold coating solution leaflet.
In 1996 another technical challenge was taken on and solved: Badotherm invented the leakage detection system for diaphragm seals. This system was based upon liquid conductivity and made an early warning possible in case of diaphragm breaks. Read more about the diaphragm leakage detection solution.
Selecting the right Diaphragm Seal configuration for your process ensures safe and lasting measurements. A series of Badotherm pressure gauge seal combinations is stationed at one of the largest chemical sites in the Netherlands, shown on the picture. Since the installation in 1999, hundreds of pressure gauge seals combinations have been installed and are still functioning. The picture shows a combination of pressure gauge seals being there from the startup to recently installed pressure gauge seals.
The construction shown on the picture is the Badotherm solid front safety pattern gauge (BDT20) with an ECB welded seal and a BSO-02 filling fluid (suitable up to 400 degrees Celsius). The construction, with the seal upper part, designed to match with the threads of the process gauge, is welded to the pressure gauge connection, and the lower part with threading matching the process connection. The welding of the pressure gauge onto the diaphragm seal eliminates the potential loss of system fill fluid through the threads in case of failing gaskets. Second advantage is that the gauge cannot be easily dismantled from the Diaphragm Seal, and reduces the risk of wrong disassembly. The ECB threaded seal design has the upper and lower part welded together, with no use of bolts or gasket and thus no risk of bolts loosening due to temperature fluctuations or vibrations. This construction doesn’t need O-rings or gaskets, which eliminates the risk of wrong gasket selection and/or leakages through the gasket.
As a leading manufacturer of Diaphragm Seal solutions, we continuously enhance the quality of our Diaphragm Seal technology. For example by evolving materials, design of components, diaphragms, filling fluids, and filling technology. These improvements effect performances like accuracy, reliability and durability. Therefore, we recently updated BaseCal, our online diaphragm seal engineering and selection tool. In the past 3 years our R&D department has extensively tested several applications. As a result we adjusted the calculation rules and optimized the fill fluid variables. In general, the response times became shorter, depending of course on the chosen fill fluid, capillary length and diameter, and ambient temperatures.
We discovered that transmitter settings, such as damping ratio and type of communication, have a large influence on the actual response time of the diaphragm seal application. Therefore, the new calculated response time excludes any delays of the transmitter and communication type.
In the new version the response time is calculated with the minimum and maximum ambient temperature, with the reference temperature of 20C. Naturally the minimum and maximum temperatures are limited by the selected fill fluid. See an example on the left.
FURTHER INTERNATIONAL GROWTH (1977 - 1987)
The business of Badotherm grew more and more. Shortly after the new facility in Dordrecht was built, it turned out the fresh new location wasn’t enough to facilitate the rapid growth. Not only the production grew internationally, also the customer demand started to come from other countries in Europe besides the Netherlands. To serve all these new international customers, Badotherm established a second location in the United Kingdom. With the start of Badotherm UK, the first step of the global network was taken. Towards the end of the eighties, Badotherm expanded further with moving part of the production towards Romania, which became Badotherm Romania. This location is now still the core manufacturing unit for Badotherm pressure and temperature instrumentation, instrument needle valve manifolds and diaphragm seal components.
Eye for the environment
During this rapid growth Badotherm also paid attention to innovation and environmental issues. Back then paying attention for environmental issues wasn’t as normal as it is today. As Mr. Peter Bastiaan recalls: “Over the years we’ve always been able to innovate and provide something extra for the customers. Never a dull moment at Badotherm. In the early 80’s when the exhibitions were full of industrial equipment and the first computers were introduced, Badotherm created a campaign with its main theme ‘the green environment’. We built a stand with real trees and plants to create a natural atmosphere. This reflected that our product range was helping our clients to reduce their waste in production processes and greatly increase their efficiency. We already took our obligation to the environment seriously, as we still do today.”
Because of the growth of our company we’re searching for a full-time Junior Instrument Maker to assist our Production Team in Dordrecht (The Netherlands).
Our location in Dordrecht is focused on the product assembly for the Europe region and besides supporting the foreign Production locations. It's also an important part of the Research & Development Center. Click here for the full vacancy with more information and the required skills.
PERIOD OF EXPANSION (1967-1977)
In 1971 Badotherm manufactured and supplied its first diaphragm seal for a Tar and Asphalt factory called OIAsFA (Olster Asfalt Fabriek), located in the East of the Netherlands. The asphalt was mostly used for covering the roofs for houses. To monitor the pressure, obviously pressure gauges were used, but the viscous process medium clogged the small process connection and the temperature was too high for the instruments. Hence the first diaphragm seals were manufactured tailored to the customer process requirements and mounted to the pressure gauge and filled with oil. Obviously, the filling technique was not that advanced as it is today.
In 1977 Badotherm built a brand-new factory in Dordrecht, to facilitate the growth of the first 20 years. The facility had a bigger office space and a far bigger production area. The facility is still the headquarters of Badotherm, and has been expanded 3 times since then. 1977 was also the year that the founder P.B. Bastiaan retired, and his two sons Peter and Niek took over the company.
This year Badotherm is celebrating its 60 year anniversary. The coming months we will take a closer look at the history of the company, by highlighting the most important events of each decade.
THE START AND BEYOND (1957 -1967)
It all started in 1957, when Mr. P.B. Bastiaan founded Badotherm as a production and repair shop for pressure gauges and thermometers. The name Badotherm was officially introduced in 1959. The company name stands for the family name ‘BAstiaan’, the location ‘DOrdrecht’, and the products ‘THERMometers’. In 1960 we produced our first own pressure gauge model. A few years later, when the technical possibilities evolved, we introduced our stainless steel pressure gauges. Nine years after the start of the company, the first son, Niek Bastiaan, joined Badotherm to help his father with the growing business.
Recently Badotherm took over the customer base of ENFM. And Remco Donkervoort, the former Director of ENFM joined Badotherm. Remco and his new colleague Sander, Sales and Marketing Director at Badotherm, gave an interview in the Dutch magazine Signalement about this change and how two of the before biggest competitors in the pressure gauge industry can now work together.
Read the whole interview in the link below:
Badotherm, founded in 1957, is celebrating its 60th anniversary this year. Back in 1957, Mr. Pieter Bastiaan started the company in the city of Dordrecht as a thermometer repair shop. Unfortunately, our founding father passed away, so he’s not able to see how his two grandsons now lead the company and expanded the company with several offices around the world.
Next to the thermometers, Badotherm has grown into a respected manufacturer of high quality stainless steel pressure gauges. Nowadays we’re one of the leading companies in the manufacturing and assembly of diaphragm seals to pressure instruments.
During the year, we will have several festivities to celebrate the start of the company and to thank our employees and customers around the world for the business during all those exciting years. Without them, we wouldn’t have been the company we are today.
Why the name Badotherm?
Not many of you may know the story behind the name, but the explanation is rather simple: Taking the first letters of the family name, the city and the first product, you get the name Badotherm.
Badotherm and Azbil Europe recently signed a European partnership agreement for the supply and mounting of diaphragm seals to their transmitters. Azbil has selected Badotherm as partner for diaphragm seals. Azbil, headquartered in Bruxelles, Belgium has a network of distributors to cover the European region, which will be supported by Badotherm. Just like Badotherm, Azbil has a solution driven approach to satisfy customer requirements.
Gunter Verdeyen, Sales Manager Azbil Europe, commented: “It is a pleasure to work with Badotherm, a flexible organization that quickly turns to the needs of our customers. With their diaphragm seals we are now able to cover a wide range of solutions to our customers”. Patrick Bastiaan, Managing Director Badotherm, added: ”It’s always nice to confirm a relationship in a formal way. However it is the result of our continuous daily support and our strive to become a better company every day, by making our customers more than satisfied with our products and services. Our collaboration with Azbil is yet another recognition of our focus on quality and putting our customers first”.
Since their founding in 1906, Azbil Group (formerly Yamatake Group) has drawn on its advanced measurement and control technologies. Azbil was established against a backdrop of growing interest in the environment and a reappraisal of Europe's energy policies. Azbil’s technology is used in factories and plants to create the ideal balance between people and production. Their long history of innovation in measurement, control and environmental protection enables them to provide divers product solutions and excellent service. Visit their website for more information.

Since many years SAPREF, situated in South Africa, is working with Badotherm diaphragm seals, together with the Honeywell channel partners for its Alkylation unit. SAPREF is the largest crude oil refinery in Southern Africa.
Due to the extreme corrosive environment, all wetted parts are made of Monel 400. In this construction, Badotherm uses its USL diaphragm seal type with the lower part in Monel 400, but with welded flush valves and full penetrant welded welding neck flanges. Off course, all are duly certified. The Honeywell transmitter is a STD820, which is connected with the diaphragm seal by means of a full welded construction. Further, for increased chemical resistance and to prevent hydrogen permeation, there is a 40-micron thick layer of 24 CRT gold applied. This application, specially made for these hard circumstances, has a proven track record for SAPREF.
Badotherm is continuously adding new diaphragm materials to its scope of supply. Adding new diaphragms is a complex activity. Next to finding the right materials, it also asks for extensive R&D activities, like testing diaphragm pressing techniques, flexibility calculations, prototyping, and weldability. Recently we added the following materials:.
Below the complete list of diaphragm materials:
Diaphragm material availability has to be complementary with the body material of the diaphragm seal construction and the specific (welding) requirements of the materials. For more information, see the datasheets where you can check what materials are possible and suitable for specific diaphragm seal types. Badotherm aims to support their customers with the supply of the best material possible to meet their process requirements and corrosion resistance. Badotherm however does recommend or select any material; this is and remains always the end responsibility of the end user.
To be able to swiftly respond to customer and market requirements, a holistic approach to product engineering is more and more important these days. At Badotherm we work with SolidWorks (3D). We use the software for our product engineering and process development to ensure a seamless, integrated workflow. Design, verification, sustainable design, communication and data management can all be integrated in the program. Our designers and engineers can span multiple disciplines with ease, which shortens the design cycle and increases productivity so we can faster deliver innovative products to the market. We work together with Design Solutions [link] to make full use of the features of SolidWorks.
To show you how this process works in our daily operations, we made a company video together with Design Solutions.
Rosemount has recently introduced its wireless pressure gauge. Basically, it is just the measuring element of the 2051 Wireless Pressure Transmitter with the look and feel of a ‘conventional’ pressure gauge. For its benefits and specifications we refer to their website.
Protection against Harsh process conditions
Just like the conventional bourdon tube pressure gauges, also these wireless pressure gauges need protection from the harsh process conditions. Of course, Badotherm Diaphragm Seals are fully suitable for the Rosemount Wireless Pressure Gauge and can be extensively tested in our factory. From the Diaphragm Seal perspective, it can be considered as a pressure transmitter. Earlier this year, Badotherm has supplied the first units the industry.
Recently we had a successful inspection of the pressure and temperature instrumentation for Shell Southern Swamp Associated Gas Solutions (SSAGS) in Nigeria. This SSAGS project is the latest project designed to manage natural gas that is produced along with oil while maximizing the use of existing flow-station assets.
For Badotherm the project consisted of the supply of more than 345 pressure gauges with related accessories. Such as Diaphragm Seals, snubbers, cooling towers and overpressure protectors, mounted to Multi-instruments and monoflanges. All according to the strict requirements of the MESC and DEP specifications. Further, it consisted of 131 barstock thermowells with bi-metal temperature gauges. Materials that were used are Monel 400, Duplex F51 and AISI 316(L). All materials and instruments were fully tested and with full material traceability.
The Southern Swamp area comprises 16 fields, of which 12 are currently producing. The fields lie in the coastal swamp area. 65 km south of Warri, with 100 oil wells and flow lines currently producing through four flow stations (Benisede, Opukushi, Ogbotobo and Tunu). Oil is transported via the Trans Ramos pipeline to the Forcados terminal. Under the SSAGS project, gas will be exported to Escravos Lagos Pipeline System (ELPS) via the existing pipelines and a new pipeline that will be installed.
At Badotherm we take care of our employees by providing safe and healthy working conditions. We try to provide a stimulating environment in which their talents can be developed and continuous learning is guaranteed. We further encourage our employees to live a responsible and healthy lifestyle. As such, we stimulate exercising. For instance by organizing sportive events such as cycling. Next to that we always try to link charity fundraisers to such sports events. A win-win situation: exercising for a good cause!
Tour de Rotterdam
For example, a few weeks ago we joined the Tour de Rotterdam. A cycling tour to raise money for Diabetic research. The tour takes place in the surrounding area of the HQ of Badotherm. With a team of enthusiastic colleagues and relations we finished the 80 km tour.
I Am Sport
Next to activities like this we are dedicated to make contributions to the communities where we operate in. That’s why we’ve linked ourselves to the ‘I Am Sport’ foundation. They are dedicated to raise funds for ill and needed children by sportive events. Currently the foundation is raising money to fight Spinal Muscular Atrophy (SMA). This incurable disease manifests in various degrees of severity, which all have in common progressive muscle wasting and mobility impairment. Proximal muscles and lung muscles are affected first. SMA is the most common genetic cause of infant death.
I Am Sport for Guus
September 5th they will climb the Mont Blanc to raise funds for Guus, a young boy with SMA. They help him and his parents to build a new room in their house at the ground floor with all related facilities, as he can no longer climb the stairs. See the special website (in Dutch) they made for Guus for more information. There you can also donate money to help this family fight against this terrible disease.
Badotherm is pleased to announce its sponsorship of UreaKnowHow.com. UreaKnowHow.com is an independent group of nitrogen fertilizer specialists with an impressive number of years of experience in designing, maintaining and operating urea plants. UreaKnowHow.com’s mission is to support, facilitate and promote the exchange of information within the nitrogen fertilizer industry. It’s main goal is to improve the Safety and Performance of all nitrogen fertilizer plants worldwide.
Therefore the network fits well with Badotherms mission to supply the best performing and most durable diaphragm seals solutions. Sponsoring this network was a logical next step. We have a wide range of diaphragm seals to meet the harsh requirements of the urea and fertilizer industry. We developed solid diaphragm seal solutions equipped with UREA grade materials, or tantalum (BRF design) to even full zirconium extended type (EXT-FSO) diaphragm seals.
Although maybe not that common, also pressure switches need to be protected from the harsh process conditions by diaphragm seals. We often show our capabilities for diaphragm seals with pressure transmitters, but we also mount our diaphragm seals to pressure switches. And of course our Badotherm pressure gauges.
All these instruments need to be protected against the harsh process conditions. As for the pressure transmitters, we have large experience with the leading pressure switch manufacturers. We regularly work with all manufacturers, such as Beta, United Electric, Barksdale and many others. See the picture on the left of a US-F seal with a Beta switch.
It is generally recommended (when used in combination with diaphragm seals) to select pressure switches with welded diaphragms and, if possible, a vacuum protection plate. These are the best suitable options for vacuum filling with the seals. If not available, it is still possible. But keep in mind pressure switches with an O-ring do have a leak rate like any other O-ring connection. Pressure switches don’t come with a calibration certificate, but with a set-point confirmation certificate. Of course, material certification on the diaphragm seal wetted parts materials can be supplied according 3.1 EN10204.
The last years there has been a large increase in the requirements for flush rings, flush flanges, reducer flanges and complete assemblies with special constructions with valves and extension with related requirements.
The flushing flange or ring is used for flushing solutions combined with diaphragm seals. This type of flushing flange or ring is clamped between the process nozzle and diaphragm seal. It is used with flanged or pancake style remote diaphragm seals. Commonly, they have one or two threaded holes in the side of the ring called ‘flushing connections’.
It is unusual to order a calibration/flushing ring without flushing connections. However it can be used without, as a spacer or a heat dissipater. They’re sometimes called flushing rings, because the flushing connection on the side of the ring allows the user to flush out buildup on their process diaphragm. The main advantage is that you can perform this task without disconnecting the remote seal from the process flange. Sometimes they’re also called calibration rings, because the flushing connection on the side of the ring allows users to apply a known pressure source and consequently calibrate the unit against that known pressure. Next to that, flushing constructions can be made with needle valves and extensions.
The flushing ring should be seen as a diaphragm seal accessory that is carefully designed to optimize the use of the diaphragm seal in your process conditions, or to ease the installation and protect it against damaging during installation.
More information about Flushing rings and assemblies here.
The 3051H high process temperature pressure transmitter has stopped being manufactured, therefore Badotherm developed a perfect new solution for this type of requirement. In short, the new solution makes it possible to continue proceeding high process temperature (capability up to 200°C) for measuring differential or gauge pressure with a direct mounted solution to fit to the manifold according the IEC 61518.
The PTH seal construction is designed to make the transmitter suitable for mounting to the process without capillary. The connection is according the International Standards of IEC 61518 to fit manifolds. The maximum process temperature is standard 200°C, however optionally this could be increased to higher temperatures, in combination with different fill fluids. Wetted part materials are standard AISI316(L),but can be varied depending on the process conditions.
Badotherm differential pressure gauge model BDT13 has been around for quite some time. The BDT13 is built on the diaphragm seal technology of Badotherm. With this special approach we’re able to produce a differential gauge with high accuracy over the full scale value of the range. The standard execution is executed with in full 316(L) stainless steel.
This pressure gauge is typically used for applications in the chemical, petro-chemical, oil & gas, power & utilities, machine building and general process industries. The BDT13 can also be equipped with diaphragm seals.
Recently, we used an interesting mix of materials to meet the specific requirements of a customer. The BDT13 with stainless steel, fixed with super duplex bolts and nuts, was further equipped with two 3” cl 300 BRF type seals, with flange material in 6MO / UNS31254 and Hastelloy C276 diaphragm material.
Do you also have specific requirements? Don’t hesitate to contact us. We’re always happy to explore the possibilities for your specific situation.
Lately, several customers are asking us about our position regarding to ‘conflict minerals’. Therefore we want to make a statement to clarify our position in this conflict. Obtaining conflict-free minerals is part of Badotherm’s Corporate Social Responsibility. Of course, we support ending the violence and human rights violations in the mining of certain minerals from the location described as the ‘Conflict Region’.
This region is situated in the eastern part of the Democratic Republic of the Congo (DRC) and the surrounded countries. As a result of this conflict the U.S. Securities and Exchange Commission (“SEC”) adopted final rules to implement reporting and disclosure requirements related to ‘conflict minerals’, as directed by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. The rules require manufacturers who file certain reports with the SEC to disclose whether the products they manufacture or contract to manufacture contain ‘conflict minerals’ that are necessary to the functionality or production of those products. The term ‘conflict minerals’ is defined as columbite-tantalite, also known as coltan (from which tantalum is derived), cassiterite (tin), gold, wolframite (tungsten), their derivatives or any other minerals or its derivatives determined by the Secretary of State that are financing the conflict in the Democratic Republic of the Congo or an adjoining country.
Because of our position regarding this conflict all suppliers of tantalum and gold in our supply chain need to provide us with a statement of compliance that claims conflict-free minerals, i.e. a raw material statement and/or a completed Conflict Minerals Reporting Template (CMRT). As a result, we don’t collaborate with suppliers that fail to comply with this statement of compliance.
On 24 November 2015 Patrick Bastiaan (Vice President and Managing Director of Badotherm process instrumentation) has signed an agreement with Jet-Net; the Youth and Technology Network in the Netherlands.
Jet-Net is a collaboration between businesses, education and government. In the last decade students have enrolled less in technical education, while the demand for technically trained staff is rising. The purpose of Jet-Net is to give students a realistic view of technology and to encourage them to choose for technical education.
Badotherm is going to support schools by giving guest lectures, expert meetings, company visits and research assignments and collaborates in developing teaching materials. Patrick Bastiaan: "We would like to tell young people how interesting and important technology is. By showing them how Badotherm is driving innovation, I am sure more students will choose a career in the technical industry.”

Bliss Anand, who is responsible for the assembly of diaphragm seals for the Badotherm operations in America, has recently received its ISO 14001 and OHSAS 18001 certification. For us it’s important to demonstrate the importance of health and safety subjects in our operations on a daily base. Not only for our employees but also for our customers and the society at large. Those subjects are becoming an important business driver in the present sensitive business environment.
The certifications are internationally recognized standards, enabling businesses to measure and demonstrate their commitment to environmental management systems (ISO 14001) and occupational safety and health systems (OHSAS 18001). As an example: we’re constantly focusing on preventing incidents. But also reducing health and safety related risks. It is the people that drive our business, so we want to ensure a safe as possible work environment.
Of course, all of our diaphragm seal applications meet the highest quality standards and are always brand new. But even the best products have a limited lifespan when exposed to harsh conditions. Ultimately, your pressure transmitter with diaphragm seal will start to deteriorate. Therefore we offer a comprehensive refurbishment service for pressure transmitters with damaged diaphragm seals.
A key advantage of diaphragm seals is the fact they can be renewed, without replacing the entire pressure instrument. The substitute seal will function just as a new instrument, but without the higher costs and longer downtime associated with buying a whole new transmitter. Next to the savings, the turnaround time can be really short. When the parts are available in stock, the turnaround time can be 24 to 48 hours. Standard lead times for refurbishment are approx. 2 weeks. For contact details of our America office:

Molten salt heat storage is becoming a more and more dominant method for Molten Salt Parabolic Trough CSP (MSPT-CSP) technology. Thereby the need for measuring the pressure at 565 degrees Celsius is also increasing.
The merits of the MSPT-CSP system are apparent:
Badotherm is pleased to support this green development with its patented HTDS design, which is perfectly suitable for measuring the pressure at these process conditions.

LGP stands for Low Gauge Pressure, and allows measurement with diaphragm seals of extreme low spans for GP applications. The use of a standard diaphragm seal in combination with the very low-pressure ranges implies relatively high temperature effects. These high temperature effects, and especially ambient temperature effects, result in unstable and inaccurate gauge pressure measurement.
Since several years, Badotherm has developed a solution for low-pressure GP applications. This solution is referred to as LGP and can be used in combination with seal type BF, BRF, USLF, EXT. To give an indication of the performance improvement between a standard diaphragm seal and the LGP solution: by using the same process connection size the minimum recommended span that can be measured reliably by LGP reduces from 200 mbar to only 5 mbar-g. The Total Probable Error (TPE) is therefore improved with a factor 7, compared to a traditional diaphragm seal.
Of course, the LGP measurement is also available in BaseCal: style 8 LGP. So see for yourself what this solution can do for your measurements.
Recently pressure transmitter manufacturers have developed a new system for differential pressure measurement (e.g. ERS systems from Emerson or Endress+Hauser). To complete these transmitters with a suitable diaphragm seal, we successfully developed and equipped these systems with our diaphragm seals. Both the Master and Slave transmitters are assembled and supplemented individually with a diaphragm seal. These are tested and calibrated separately. As a result, there is a test certificate for both transmitters. Afterwards the differential pressure measurement could be checked, although it is a mere electronic calculation.
These new additions imply that the complete range of Badotherm diaphragm seals are now also available for electronic differential pressure measurement systems. Of course this new systems still have their (technical) limitations, not related to diaphragm seals. We are constantly improving to make the most suitable match with our products and therefore reach the best possible measurement conditions.

At Badotherm we have recently welcomed a new team member and would like to introduce him to you: Pieter Reijneveld.
Pieter will be responsible for the account management in the Netherlands and Europe. His focus will be to support our customers to ensure our products and services stay aligned with the market and customer requirements. Although he is relatively new in the industry, his background is in business engineering, he has large experience in sales and account management. With the support of his experienced colleagues, he will learn the specifics of the instrumentation industry fast. He will support the customer with their specific questions and measurement challenges and will ensure the experience and knowledge at Badotherm is available for all customers. On a personal note, after living in Australia for 10 years, he returned to the Netherlands with his family earlier this year. When he is not working for Badotherm, he enjoys spending time with his family and he loves to sail, both competitive and recreational.
Vacuum often occurs unintentionally. For example during cleaning and fast cooling processes. Connections with gaskets have a leak rate that is especially challenging when vacuum occurs. In these situations it is recommended to prevent gaskets and use welded constructions instead. For diaphragm seals, this means a full welded construction between the capillary, the transmitter body and the welding of other potential leak points.
Badotherm has full welded constructions available for all leading transmitter brands. Next to the selection of a full welded construction with the presence of vacuum, we also recommend you to verify the suitability of the filling fluid for vacuum conditions (see the vapor pressure curve). It is also important to not forget to mount the instrument below the (lowest) diaphragm seal in order to protect the instrument at all possible conditions (50 cm).
Some extra Badotherm facts:
Flushing (drip) rings, flush flanges or reducer flanges. These are all accessories to the Diaphragm Seal assemblies as manufactured by Badotherm. They are used to vent the process connection in order to obtain correct measurement; also they can be used for a calibration check on the instrument. Further they are often used to clean the process connection on a regular basis. The flushing ring or flange has to be mounted between the process flange and the diaphragm seal.
Often these rings are requested in combination with flush valves. Either type BDTV910 or BDTV911 , which has an extended connection on the process side and is specifically designed to mount on flush rings. They can be fitted to the flush rings, but it is also possible to have them socket-welded (SW) or butt-welded (BW) to the body material. The welds are often requested in combination with stringent qualifications. As such Badotherm supplies these, upon selection, with complete WPS, WPQ and PQR.

Last quarter we added Badotherm Far East to the IT/ERP backbone of Badotherm. The implementation went successful and our Badotherm Far East office is already experiencing benefits from the support and increased control of all vital business processes. Last year the ERP implementation was done for the Houston office, to make use of the same platform as Badotherm Headquarters in the Netherlands. As it contains a detailed product configurator, it ensures same built-up of each application, with same parts, same bill of materials, same routings, same production and testing procedures to ensure the same level of high quality products.
Microsoft Dynamics Enterprise Resource Planning (ERP) software gives our people the tools they need to connect and manage the entire business. From financial and supply chain management to manufacturing operations: it gives them the insights they need to make smart operational decisions. Our customers in Far East region will benefit from this step ahead in our strive for operational excellence. We are constantly searching for innovations and solutions to further optimize our processes in order to improve our services for our customers.
The raised face covered Diaphragm Seal is the solution for flanged seals with exotic wetted parts. The Diaphragm Seals are designed to prevent contact of the process medium with the AISI316 seal body materials. All wetted parts of BRF/BRC type Diaphragm Seals are covered with an exotic diaphragm material.
The double weld technology makes it possible to keep the wetted parts of the diaphragm material properties uninfluenced by the welding operation to the 316 body material. The inner weld is located on the wetted part and is welded with the latest resistance weld technology. The resistance weld is helium tested in order to exclude leaks in the welded area. The outer weld is welded with TIG welding technology and is a non-wetted part. The gasket surface between the resistance weld and the TIG weld is fully covered with the exotic diaphragm material and has the appropriate roughness. All of the different weld technologies are used to reach the most ideal conditions.
Badotherm recently adopted Lean Six Sigma as main continuous quality improvement program. Lean Six Sigma is a set of techniques and tools that seeks to improve the quality output of processes by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes.
It uses a set of quality management methods (mainly empirical) statistical methods, and creates a special infrastructure of people within the organization who are experts in these methods. So called Champions, Black Belts, Green Belts and Yellow Belts for example. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has quantified value targets. For example: reduce process cycle time, reduce pollution, reduce costs, increase customer satisfaction and increase value.
Badotherm has 2 black belts, 9 green belts and 10 yellow belts across the main factory location in Romania and in its headquarter in the Netherlands.
For a valued customer in Kazakhstan we recently supplied our ECH seal, therefore it withstands pressure up to 1000 bars. For this application the seal wetted parts were made of Hastelloy C276 material with a max operating pressure of 624 bars. The BSO-41 fill fluid was selected to cover the operating temperature of minus 40°C. Another requirement was that the material needed to be fully compliant to NACE MR01-75 (ISO-15156).
The ECH is a complete welded construction and designed for those applications where the process conditions are such that direct mounting of the instrument can’t be done. Applications are aggressive processes treatment, or when special wetted parts materials for pressure gauges are required.

Badotherm designs, engineers and manufacturers all diaphragm seals and component in-house, respecting the relevant international standards. Controlling the complete manufacturing, Badotherm ensures a perfect fit between the components, resulting exact the right amount of fill fluid in the system to ensure perfect functioning and limit the temperature effects as much as possible. All our facilities are ISO9001 and/or ISO14001 certified. Some key product features:
A temperature compensator (TC) is typically recommended to optimize the response time. It is often used in situations with long capillaries and high process temperatures and/or low ambient temperatures. When the specifications of the process prescribe the use of a fill fluid with high viscosity this might result in unacceptable response times. A temperature compensator is developed to overcome this problem. By using the high viscous fill fluid in the part between the diaphragm seal and TC, the fluid keeps a relative high temperature resulting in a low viscosity. When after the TC a standard fill fluid with low viscosity is used this results in an acceptable overall response time. See the photo with a Rosemount 3051 transmitter with a Badotherm diaphragm seal, type USL-F, and direct mounted temperature compensators.

Both Canada and the United States use the ASME Section VIII-1 code for pressure vessel construction, but Canada has a CSA B51 standard that provides a more restrictive definition of what a pressure vessel is. Badotherm diaphragm seals of course comply with these requirements and Badotherm has a CRN registration for the following states: British Columbia, Ontario and Alberta.
For more information about CRN registration, please contact our Houston office.
In many industries it is required to have a ‘plastic’ or polymer coating over the diaphragm seals or wetted parts of the diaphragm seals in order to project your instruments. These coatings can be PTFE, FEP, PFA or ECTFE, each with their own characteristics.
Typically all of these coatings give excellent chemical resistance in heavy-duty corrosion applications. However, chemical resistance is only secured when the coatings have a thickness of approx. 2 mm. Due to the nature of the flexible and thin diaphragm (75μm) of the diaphragm seal, it does not allow a thick layer of this polymer coating to be applied, as it would make the diaphragm less flexible and thus no longer transferring the pressure accurately. To maintain the flexible and sensible function of the diaphragm, only a 35-50μm thick layer can be applied, which is not sufficient to warrant chemical resistance. It may provide additional protection for chemical resistance and it may make the instrument more durable, but this cannot be warranted. It is also often used for non-stick purposes. It ensures that the process medium does not stick to the metal diaphragm and therefore the flexibility of the diaphragm is not deteriorated.
A PTFE lining (approx. 2mm thick) cannot be used for protecting the diaphragm, but it can be used to protect the inner part flange (the lower part). Due to its thickness, this does provide excellent chemical resistance. Often customers use a combination of options: a tantalum diaphragm (for the wetted parts) and a PTFE lined lower part of the seal (together with an inert filling fluid that is often used for chlorine applications) or a coated wetted part (incl. diaphragm) with a PTFE lined lower part.
Please note that these coatings and lining have temperature limitations. Badotherm can always support you, or help you in choosing the right option.
Diaphragm seals can consist heavy flanges and are sometimes hard to handle. As such, we developed a simple accessory to facilitate easier handling of these heavy seals: lifting handles.
We recommend to use these handles from class 600 and above for size 2” and 3”. The lifting handles provide a spot to properly hold the instrument and to facilitate an easier positioning towards the nozzle. This is especially useful for the vulnerable diaphragms. Using the lifting handle results in a reduction on mechanical damage of the diaphragm. And due to the easier handling, fewer people are needed during the installation and/or no additional equipment is required. The lifting handle also supports an increased safety for the operators and therefore helps creating a safer work environment, as the instrument is more manageable. A simple accessory, but the installation and maintenance team will be thankful for this addition.
Normally we’d like to have our products and services do the talking for us. However, recently our Managing Director Patrick Bastiaan gave an interview in the Dutch magazine Signalement about his vision and mission with Badotherm. Patrick talks about the ambition of Badotherm and their globally leading position as a manufacturing engineer. Read the whole interview in the link below:

You want to make your processes as accurate as possible, therefore it is important to select the right diaphragm seal. For deciding which instrument is required you need to know which one makes the best fit. To comprehend beforehand what the performance of the instrument will be, many of our customers use our tool BaseCal. This tool takes all of the process conditions into account and therefore makes it easier for them to choose the right diaphragm seal.
Next to the Total Probable Error, the response time of the instrument is also very important. In the following article you can read more about the importance of response time for one of our key customers: Shell.
Article: Response time for Shell
The presence of vacuum in a process is a very important factor when selecting the Diaphragm Seal fill fluid and the way of mounting of the instrument. The relation between the vacuum value and the process temperature should be checked in the vapor pressure curves of the fill fluid to see whether the fill fluid is suitable. When mounting the instrument for a vacuum application, the instrument should be placed below the (lowest) Diaphragm Seal to protect the instrument. For absolute pressure measurement the instrument should be mounted below the diaphragm seal in order to protect the instrument at all possible conditions.
As a rule of thumb, we recommend to place the instrument at least 50 cm below the (lowest) Diaphragm Seal. The 50 cm distance, between nozzle and instrument creates a positive fluid column, which protects the instrument from measuring absolute zero. With this mounting style the instrument has additional protection before it measures absolute zero. This is presented in the picture on the left.

For one of the largest mineral fertilizer producers in the world, located in the Netherlands, Badotherm recently supplied an extraordinary type of seals. This customer was looking for a different solution, since the current tantalum lining of the extended seal did not meet up their durability expectations. The tantalum diaphragms came off after a relatively short time in process. Hence they turned to Badotherm for a solution. After discussing with the metallurgist of the company, zirconium material was selected as superior corrosion resistant material for the process and the most efficient design was manufactured (FSO-EXT).
Zirconium as base material may be an expensive material, but the initial higher cost of the instrument is easily earned back with the increased lifetime of the instrument. It is known that the tantalum linings are often used in the UREA industry. But in some occasions, zirconium could be the most durable and efficient solution.

Tantaline® is a surface treatment that differs from all other tantalum coatings which are sprayed or dipped. It is really a tantalum surface alloy. This surface alloy was designed with high performance in mind for aggressive applications that require corrosive protection or inertness. Due to the process of applying the surface treatment, it is not possible to apply this to the diaphragm itself, however for other components such as flush rings, lower parts, thermowells and manifolds this is an interesting solution.
For several customers Badotherm recently supplied components with Tantaline® surface treatment:
• For the Qarn Alam project, the required thermowells had to be compatible to 36% HCL concentration. The materials of construction should therefore be tantalum or zirconium. Tantaline® treatment of the thermowells was chosen as the most effective solution.
• For a leading Dutch specialty chemical company we supplied diaphragm seal type USF with a tantalum diaphragm and a lower part with a Tantaline® treatment. In this case, it replaces a PTFE lining.
• For the Laggan Tormore project, we supplied seal type BRF with tantalum diaphragm and a flushing ring with Tantaline® treatment, including the blind plugs. One of the benefits of Tantaline® treatment is that is it suitable for threaded connections (e.g. the plugs).

For Sabic, our customer in Bergen op Zoom, The Netherlands, we recently supplied a transmitter seal application with a 24 carat, 40µm layer of Gold Coating for the diaphragm seal on complete wetted parts. This goldcoating makes the diaphragm seals both corrosion resistant and perfectly protected against hydrogen permeation. A gold coating of 25µm is market standard, but the 40µm thickness option is for increased lifetime and durability and often used when customers want sure! Additionally, the lower part of this seal type USL-F was equipped with a 1mm thick PTFE layer to protect the material against mechanical attack of chlorides. The suitable inert filling fluid BSO-25 meets the process temperature and pressure requirements.
