AST2000 Hydrogen Pressure Sensor
316L Stainless Steel, Media Isolated Pressure Sensor for Hydrogen Applications
Overview
The AST2000 series is now available for hydrogen pressure sensing
applications. Tested to a variety of hydrogen and automotive standards,
the AST2000 series combines the best mechanical design for hydrogen
measurement with high performance digital compensation.
Benets
l One piece design
l All 316L wetted material for optimal compatibility
l No oil-lled cavities leave no chance of containment
l Non-welded diaphragm eliminates leak paths and weak points
l Digitally compensated
l Krystal Bond™ Technology
Applications*
l PEM Fuel Cells l Hydrogen Storage
l Hydrogen Filling Stations l Test Stands
l Back Up Power
