Druck solutions for the hydrogen market

As a market leader in pressure measurement for the past 50 years, we know that hydrogen applications pose a unique challenge for pressure sensors due to the harsh nature of the medium. Long term exposure to hydrogen gas degrades the performance of a pressure sensor, specifically through Hydrogen permeation and embrittlement of the isolation diaphragm, meaning the construction of a hydrogen sensor is key to maintaining accuracy and stability.

Druck has a range of hydrogen compatible pressure sensors which can be used across a range of applications, from gas turbines to hydrogen filling stations.

The high-performance barrier coating and carefully selected substrate material used in the isolation diaphragm for the UNIK5000H and the RPS/DPS8000H minimises the impact of hydrogen permeation and extends the life of the pressure sensor, offering longer term stability and use in harsh applications.


Performing in hydrogen

The UNIK5000H is a hydrogen compatible pressure sensor that has been design based on the successful UNIK5000 industrial, configurable sensing platform.

With pressure ranges from 700 mbar (10.2 psi) to 700 bar (10,000 psi), the UNIK5000H pressure sensor is ideal for test, networks and filling station applications. 

The stainless steel 316L construction of the UNIK5000H provides excellent resistance to hydrogen embrittlement. Permeation can affect the performance of all sensor technologies and the UNIK5000H uses an optimised barrier coating that limits hydrogen permeation and is unaffected by the presence of impurities.

We have taken the highest accuracy, industrial pressure sensor on the market and combined it with our innovative coated diaphragm technology to create the RPS/DPS8000H sensor.

With unrivalled accuracy and stability from 0 bar to 200 bar, the RPS/DPS8000H is an ideal solution for harsh hydrogen applications including gas turbines or fuel test.

The combination of the power of the TERPS technology and the quality, reliability and flexibility of the RPS/DPS8000H Series offers a truly unique solution for high accuracy and high stability pressure measurement in a hydrogen rich media.
