HISPEC – HI2200/2300 series of high temperature pressure transducers with state-of-the-art Silicon-on-Sapphire sensor technology offer levels of accuracy and performance previously unobtainable or prohibitively expensive. It is capable of operating at constant 200°C both media and ambient.

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 completed sensor exhibits virtually no hysteresis and excellent long-term stability. With outstanding insulation properties, the sapphire substrate protects the strain gauge circuit and allows the sensor to operate over a very wide temperature range without loss of performance.

With pressure ranges from 0-1bar to 0-1500bar, the high temperature HISPEC transducer is available in two options; model HI2200 offers a non-compensated and un-rationalised signal output of between 10mV/V and 20mV/V, whilst model HI2300 is fully temperature compensated with a rationalised 10mV/V signal output. All models are available with either PTFE cable outlet or military bayonet style plug to MIL-C-26482, both of which are rated for use at 200°C. This means that not only does the transducer perform effectively at high media temperatures but uniquely can be used in environments where there are elevated ambient temperatures of up to 200°C. For instance this device may be mounted inside an oven or thermal chamber.
