Hydrogen Pressure Transducer

Pressure Transmitters for Hydrogen Compatible ApplicationsThe piezoresistive stainless-steel measuring cell has expecially been adapted to the chemical and physcial properties of hydrogen. The entire sensor consists for a single piece, which is designed to prevent embrittlement of the metal surface by ionized hydrogen. It is also absolutely vacuum-tight and elastomer-free Leaks caused by material fatigue on internal seals are thus eliminated from the outset. It has no disturbing pressure transfer fluid and no large pressurized surfaces. The membrane is of a very robust design.

The link-in to the connection pins is made by wedge-wedge bonding and is therefore absolutely stable even at low temperatures, or for shocks or vibrations. The measruing bridge evaluates via a mixed singal ASIC. The SPT-H2 can also be used for application where EC79 certification are important
