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.

Benets

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
