    Product Description

    Multifunctional differential pressure transmitters with air flow measurement and Modbus communication
    DPT-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. DPT-MOD requires less wiring than the traditional 3-wire transmitters because multiple devices can be connected on 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:
    o Measure and monitor in-duct volume flow, velocity or
    differential pressure
    o Measure and monitor air flow across centrifugal fans
    Multiple selectable measurement units:
    o Volume flow: m3/s, m3/h, cfm, l/s
    o Velocity: m/s, ft/min
    o 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


    RS-485 Modbus (RTU)

    Accuracy (from applied pressure):
    (model 2500)

    Pressure < 125 Pa = 1 % + 2 Pa
    Pressure > 125 Pa = 1 % + 1 Pa

    Accuracy (from applied pressure):
    (model 7000)

    Pressure < 125 Pa = 1.5 % + 2 Pa
    Pressure > 125 Pa = 1.5 % + 1 Pa

    Zero point calibration:

    automatic with autozero element (-AZ), by pushbutton or via Modbus

    Measuring units:

    Pressure: Pa, kPa, mbar, inchWC, mmWC, psi
