Relative pressure transmitter PR3900

piezoresistivesiliconanalog

The PR3900 pressure transmitter is designed to meet the majority of industrial pressure measurement applications where installation in an explosive and hazardous area is required. Designed and certified in accordance with the ATEX and IECEx approval this product is intended for installation and operation in potentially explosive atmospheres in zone 0 gas group IIC, temperature class T4 and zone 20 dust and M1 mining. Protection is by intrinsic safety when used with a safety or isolation barrier. The PR3900 provides a stable and accurate intrinsically safe two wire output signal of 4-20 mA when powered through a safety or isolating barrier such as MTL7706+, MTL5541 or other similar protection device. The unique Silicon-on-Sapphire sensor technology provides outstanding performance and gives excellent stability over a wide temperature range. The sensor endures higher over- pressures and provides superb corrosion resistance., with virtually no hysteresis. The outstanding insulation properties, allows the sensor to operate over a very wide temperature range without loss of performance. The fully welded stainless steel enclosure makes the product extremely robust and able to withstand corrosive demanding environments. Electrical connection is via a strong and durable polyurethane cable with integral vent tube for effective gauge venting to atmosphere. In addition to the standard 1/4" NPT female connection optional 1/4" and 1/2" BSP male and 1/2" NPT male process connections are also available. Pressure ranges available from 0-10 bar to 0-1,500 bar.
