Differential Pressure Transmitters


Rugged differential pressure transmitters from Orange Research are designed for high line pressure applications in filtration, flow, and level measurement. The 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). 

The user simply selects the desired configuration. With pressure bodies made from solid blocks of stainless steel, brass, aluminum or PVC and rugged, proprietary sensors, these transmitters withstand severe environments and high line pressures while maintaining 2% full-scale accuracy (for standard-size DP models) and 5% (for miniature DP models). The transmitters meet a variety of requirements, from NEMA-4X to Class 1, Div. 1 or Div. 2, IP65, CSA, and many more. The DP transmitters are also available with optional dials for local readout. Dial diameters from 1 in. to 6 in. are available with many dial options to customize the local readout of the device.
