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

Communication:

RS-485 Modbus (RTU)

Accuracy (from applied pressure):
(model 2500)

Pressure < 125 Pa = 1 % + 2 Pa
