Approved for use on H2-powered vehicles operating at up to 900 bar, the model AST20000H2 hydrogen ASIC pressure sensor, from American Sensor Technologies, is also suitable for hydrogen-related applications within the material handling, stand-by power generation, food, pharmaceutical, and petroleum industries. An innovative threaded, high pressure sealing design enables it to withstand extreme cold and heat as well as high operating pressure conditions. Other design features include an all 316L SS wetted sensing element with a thick pressure diaphragm (nearly 1.5mm), and one-piece construction free of welds, internal O-rings, or oil-filled cavities. These features make these pressure sensors ideal for use in hydrogen applications that present difficult operating challenges such as hydrogen permeation and embrittlement that often cause many other pressure sensors to fail. Electrically, they are available with common automotive and industrial outputs signals such as 0.5-4.5VDC ratiometric (5.0 VDC supply) or 1-5VDC & 4-20mA (10-28VDC supply). The signal is stable and linear throughout the operating temperature range of -40 to 85 °C, with typical total error band of ±2.0%.
