HISPEC - HI2000 series of pressure transducers with state-of-the-art Silicon-on-Sapphire sensor technology offer levels of accuracy and performance previously unobtainable or prohibitively expensive. 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 overpressures and provides superb corrosion resistance. The completed sensor exhibits virtually no hysteresis and excellent long-term stability. With outstanding insulation properties, the sapphire substrate protects the strain gauge circuit from electromagnetic pulse radiation and allows the sensor to operate over a very wide temperature range without loss of performance. With all titanium alloy wetted parts and a stainless steel housing the HISPEC is designed to operate in demanding
environments, while maintaining accurate performance and extremely good durability. Applications include aerospace, laboratory and test, oil and gas monitoring equipment (down-hole) and sub-sea. Available immediately in pressure ranges from 0-0.5 bar to 0-1500 bar and with electrical outputs of 0-100mV, 0-5 Vdc and 0-10Vdc.
