About the AHI2000H Hydrogen Compatible Premium Pressure Transmitter
The AHI2000H high precision transducer is designed with state of the art Silicon-on-Sapphire sensor technology, offering levels of accuracy and performance previously unobtainable or prohibitively expensive. With operating ranges up to 1,500 bar the suitability of the material for use with hydrogen is confirmed following compatibility testing based on ISO 11114-2:2017 according to the European Regulations EC 79/2009 and EU 406/2010.
The unique Silicon-on-Sapphire sensor technology provides outstanding performance and gives excellent stability over a wide temperature range. The advanced sensor design consists of a piezoresistive silicon strain gauge circuit, which is epitaxially grown onto the surface of a sapphire diaphragm to form a single crystalline structure. The sapphire sensor element is then molecularly bonded to a Titanium alloy sub-diaphragm. This enables the sensor to endure higher over- pressures and provides superb corrosion resistance. The sensor exhibits virtually no hysteresis and excellent long-term stability.
With outstanding insulation properties, the sapphire substrate allows the sensor to operate over a very wide temperature range without loss of performance. A TEDS (Transducer Electronic Data Sheet) version is available. A TEDS contains the critical information needed by an instrument or measurement system to identify, characterize, interface, and properly use the signal from an analog sensor. IEEE 1451.4 defines the method of encoding TEDS information for a broad range of senor types and applications.
Applications include aerospace, laboratory and test, oil and gas monitoring equipment (down-hole) and subsea. Available in pressure ranges from 0-500 mbar to 0-1,500 bar and with electrical outputs of 10 mV/V, 0-5 dc and 0-10 Vdc. An optional ATEX and IECEx approved version of this product is available for explosion protection for flammable gases (zone 0), dusts (zone 20) and mining areas (group I MI)
