Gold-coating for hydrogen protection

Gold-coating for hydrogen protection

Hydrogen is nature’s simplest and smallest atomic element. But despite its minuscule size, it can have a significant and unwelcome impact on chemical processes. Hydrogen atoms can permeate the molecular structure of a seal’s diaphragm. In order to prevent this, we have developed the most sophisticated gold-coated diaphragm seals on the market. In fact, we’re one of the few manufacturers to use a 24crt 40µm gold-coating on our seals. We also offer a wide range of gold-coatings to meet various customer and market demands.

High temperature seal up to 600°C

Higher pressure and temperatures are known to improve overall process efficiency. They also pose a challenge when it comes to monitoring. To continue accurate measuring under extreme circumstances, we have developed a diaphragm seal that withstands temperatures of up to 600 °C. This patented ground-breaking diaphragm seal lets you successfully control your chemical processes in conditions where other seals would fail.

Web-based performance tool BaseCal

Web-based performance tool BaseCal

Installing a diaphragm seal to a pressure transmitter affects that transmitter’s performance. BaseCal is our proprietary web-based performance calculation tool that helps you select the best diaphragm seal application for your process, taking every factor into account. It calculates the total installed performance of the diaphragm seal application - including the transmitter - so you know exactly what’s going on in your entire system. With BaseCal you can easily change variables and conditions, allowing you to simulate and analyse the effects of various situations.

Measuring extremely low pressures

Low pressures can be difficult to measure. That’s why we have developed a specialized innovative method with a diaphragm seal and transmitter application called Low Gauge Pressure (LGP) measurement for low pressure monitoring. This diaphragm seal is capable of measuring pressure up to 20 times lower than other conventional diaphragm seals – down to 10 mbar. A typical low pressure application is nitrogen blanketing which prevents process gasses from entering the atmosphere. But measuring and controlling the low pressure in a corrosive environment can be a challenging endeavour. With using the LGP diaphragm seals you achieve better process control, and this means considerable savings in nitrogen consumption.

Renewing your instruments

All of our applications meet the highest quality standards. But even the best products have a limited lifespan. Should your instrument’s performance ultimately start deteriorating, we offer a comprehensive repair & maintenance 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.

Process simulation for critical applications

Diaphragm seals are all about accuracy. All diaphragm seal applications are standard calibrated at room temperature. However, in the extremes of process measurement even the smallest deviation in seals may become noticeable. With our unique process simulation testing facility we can eliminate the smallest deviations by simulating various process conditions. This enables us to set each instrument we produce to its specific intended application. This additional testing is typically recommenced for critical applications with a span below 100 mbar, absolute pressures, and/or process temperatures above 150 C.
