DPT-Dual-MOD-AHU-D

Differential pressure transmitter DPT-Dual-MOD-AHU-D

DPT-Dual-MOD-AHU Modbus differential pressure transmitter is especially designed for air handling units. It has two pressure sensors with different measurement ranges (-700...7000 Pa and -250...2500 Pa), and is ideal for measuring pressure from two measurement points. It also measures airflow rate. In a typical air handling unit application, one sensor monitors the airflow across the centrifugal fan while the other sensor monitors the filter cleanliness.

Differential pressure transmitter DPT-Dual-MOD-AHU-D

DPT-Dual-MOD-AHU has two multifunctional inputs for reading 0...10 V, digital and resistive signals from external devices. Since the BMS system can read the input signals of these connected external devices from the Modbus registers of the DPT-Dual-MOD-AHU transmitter, you can use temperature sensors instead of temperature transmitters to save in device and installation costs. For example, you can connect two passive temperature sensors (Pt1000, Ni1000, Ni1000‑LG or NTC 10) to this transmitter to measure temperature at two measurement points.

Easy to commission using the device menu and jumpers.

The DPT-Dual-MOD-AHU differential pressure transmitters are typically used in building automation systems for:

  • • airflow monitoring across centrifugal fans and blowers
  • • in-duct airflow monitoring
  • • VAV applications
  • • fan, blower or filter monitoring
  • • pressure and flow monitoring
  • • pressure monitoring in cleanrooms
