Differential pressure transmitter designed for air handling units, includes an air flow transmitter.

DPT-Dual-MOD-AHU is especially designed for air handling units, combining two differential pressure transmitters into one device. It offers a possibility to measure pressure from two different points. One of the measurements can be set to show the air flow rate. DPT-Dual-MOD-AHU has a Modbus interface and an Input terminal. When using the Input terminal, temperature transmitters can be replaced with temperature sensors. As a result, you will save in costs of the devices and in the installation costs.

 

DPT-Dual-MOD-AHU series devices include:
• Multiple measurement units, field selectable via menu, including: Pa, mbar, inchWC, mmWC and psi.
• Input terminal enabling reading of multiple other signals such as temperature or control relays over Modbus


Technical details
