Hydrogen pressure sensors

AST2000H2 digitally compensated pressure sensor/transducer is designed for hydrogen pressure measurement applications. It is packaged with an SAE-3 or SAE-4 pressure port, 0.5-4.5V Ratiometric output signal, Packard Metripack 150 electrical connection and optional 1% total error band. This sensor is designed for applications including PEM fuel cells, on-board vehicle cylinder pressure measurement, hydrogen regulator pressure measurement, hydrogen filling stations, hydrogen storage containers and test stand equipment. It features the proprietary Krystal Bond Technology pressure sensing element. The thread, hex and diaphragm are all machined from one piece of 316L SS. The sensor was tested to the TÜV compatibility standard created by the EIHP (European Integration Hydrogen Program) for Compressed Hydrogen Gas (CGH2) components for on-board vehicle storage systems. Tested and approved by Detroit Testing Laboratories to an environmental test for approval on the Hydrogen HyWay 2/3. The AST2000H2 passed separate electrical environmental tests conducted by Underwriters Laboratories.
