Differential-Pressure TransmitterOrange Research”s differential-pressure transmitters are designed for high line pressure applications in filtration, flow, and level measurement. The differential-pressure transmitters are available in piston and diaphragm sensor models rated at up to 5,000 PSIG line pressures with prices starting below $100. The transmitters transform differential pressure (DP) measurement into voltage (0-5 V, 3 or 4 wire) or current (4-20 mA, 2 wire loop-powered). With pressure bodies made from solid blocks of stainless steel, brass, aluminum, or PVC, and proprietary sensors, the differential-pressure transmitters withstand severe environments and high line pressures, while maintaining 2 percent full-scale accuracy (for standard-size DP models) and 5 percent (for miniature DP models). The differential-pressure transmitters meet a variety of requirements, from NEMA-4X to Class 1, Div. 1 or Div. 2, IP65, CSA, and many more. – www.orangeresearch.com
