The Genspec GS4200 series of pressure transducers and transmitters is designed to meet the operational requirements of demanding pressure measurement applications where good quality, fast delivery and low cost are of the priority.
The series is available in pressure ranges from 0-500 mbar to 0-1500 bar. Accuracy is 0,25% with an over pressure limit of twice the rated pressure range with a standard output of 4-20 mA and easy access for re-calibration. The titanium alloy wetted parts offer corrosion resistance with versions available offering IP66 sealing for installations requiring high levels of environmental protection.
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, 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. 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.
Applications for the GS4200 series include the continuous monitoring of hydraulic systems with oil, gas, water and other process liquids, industrial, medical and aerospace industries. Also ideal for the measurement and control of pressure in refrigeration, pneumatic, compressor, HVAC and engine monitoring systems.
