Field adjustable, multi-range differential pressure transmitters for air

DPT-R8 series differential pressure transmitters are engineered for building automation in the HVAC/R industry. The most technologically advanced transmitters on the market, measuring static and differential pressure, with field selectable units, range and output, all in a single device.

DPT-R8 series device options offer:

  • AZ (autozero) function for automatic zero point calibration, eliminating the need for periodic manual autozeroing to ensure long term accuracy
  • Backlit display
  • Field adjustable span point calibration (i.e. gain)
