MILFORD, CT – Rugged differential pressure transmitters from Orange Research are designed for high line pressure applications in filtration, flow, and level measurement. The transmitters feature:

  • Availability in piston and diaphragm sensor models rated at up to 5,000 psig line pressures.
  • The ability to transform differential pressure (DP) measurement into voltage (0-5 V, 3 or 4 wire) or current (4-20 mA, 2 wire loop-powered).
  • Pressure bodies that are made from solid blocks of stainless steel, brass, aluminum, or PVC and rugged, proprietary sensors.
  • The ability to withstand severe environments and high line pressures while maintaining 2% full-scale accuracy (for standard-size DP models) and 5% (for miniature DP models).
  • Various met requirements, from NEMA-4X to Class 1, Div. 1 or Div. 2, IP65, CSA, and many more.
  • Optional dials for local readout.
  • Dial diameters from 1” to 6” that are available with many dial options to customize the local readout of the device.
