Multi-range and field adjustable, differential pressure transmitters (for air)

DPT-R8 series, the most technologically developed differential pressure transmitters for building automation to date, have been specifically designed for the HVAC/R industry. They measure static and differential pressure, and come with field selectable units, range and output, all in a single gadget.

D= display
R8= 8 measurement ranges
S= span point calibration
-40c = cold-resist model



DPT-R8 series devices include:

  •  8 field selectable measurement ranges, unidirectional or bi-directional, selectable via jumper.
  • Multiple measurement units, field selectable via jumper, including: inWC, mmWC, Pa, mbar.
  •  Proportional output options including: voltage (0–10 V / 2-10 V) and current (4–20 mA).


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)
