Optimised for hydrogen 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.
Customisable and bespoke as a standard
Custom-built from standard components, manufacturing sensors to your requirement is fast and simple; each UNIK 5000 is a “bespoke” pressure sensing solution: sensor or transducer, and still with the short lead times and competitive pricing you would expect from datasheet-standard units.
Challenges in hydrogen pressure measurement
Exposure to hydrogen gas can impact the performance of a pressure sensor, specifically via the processes of hydrogen permeation and embrittlement, hence key design aspects need to be considered with a hydrogen pressure sensor to maintain accuracy and stability.
