Differential Pressure Transmitter-MOD – PRESSURE & AIRFLOW MEASUREMENT AND MODBUS COMMUNICATION

      Categories Pressure, AIR

      Multifunctional differential pressure transmitters with air flow measurement and Modbus communication

      Differential Pressure Transmitter-MOD is a multifunctional transmitter for measuring volume flow, velocity, and static and differential pressure. The measurements can be read and the configuration done via Modbus communication. Differential Pressure Transmitter-MOD requires less wiring than the traditional 3-wire transmitters because multiple devices can be connected on serial line. Differential Pressure Transmitter-MOD can also be used with several different measurement probes such as FloXact™ or pitot tube, and air dampers.

        Differential Pressure Transmitter-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

        Differential Pressure Transmitter-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
