The PR3913 Valve-Mountable pressure transmitter has been designed to meet the requirements of the subsea oil industry and is configured to mount directly to the industry standard control valve flange arrangement. The unique Silicon-on-Sapphire sensor technology provides outstanding performance and gives excellent stability over a wide temperature range. The sensor endures high over-pressures and provides superb corrosion resistance with virtually no hysteresis. The outstanding insulation properties of the sapphire allows the sensor to operate over a very wide temperature range without loss of performance.
