Hydrogen – fuel of the future?

A pressure transmitter based on piezoresistive technology has a stainless-steel diaphragm behind which oil is found. As already mentioned, permeability is one of the problems to contend with when it comes to dealing with hydrogen; the gas can easily diffuse through the steel.
Mittels einer öl- und fettfreien Reinigung des Sensors kann eine Verunreinigung des kompletten Wasserstoffsystems vermieden werden. Zusätzlich sind sämtliche zum Einsatz kommende Wasserstoff-Sensoren für erhöhte Sicherheit (3G) ATEX zertifiziert.
