Multifunctional differential pressure transmitters (with air flow measurement and Modbus)

This multifunctional transmitter has been designed for measuring differential pressure, static, volume flow and velocity. DPT-MOD works fine with several different measurement probes such as FloXact™ or pitot tube, and air dampers.

All the measurements are read and configured via Modbus communication. An extra advantage is that DPT-IO-MOD requires less wiring than the traditional 3-wire transmitters, due to the fact that its multiple devices can be connected on a single serial line. DPT-MOD can also be used with several different measurement probes such as FloXact™ or pitot tube, and air dampers.

DPT-MOD series devices include:

  • Two selectable functions:
    Measure and monitor in-duct volume flow, velocity or differential pressure
      Measure and monitor air flow across centrifugal fans
  • Multiple selectable measurement units:
    Volume flow: m3/s, m3/h, cfm, l/s
      Velocity: m/s, ft/min
      Pressure: Pa, inWC, mmWC, kPa, mbar
  • Modbus communication protocol


DPT-MOD series device options offer:

  • AZ (autozero) function for automatic zero-point calibration, eliminating the need for periodic manual autozeroing to ensure long term accuracy
