Field adjustable differential pressure transmitter with two pressure sensors for air and an Input terminal for two analog inputs for external signal conversion into Modbus.

DPT-Dual-MOD combines two differential pressure transmitters into one device. It offers a possibility to measure pressure from two different points. It 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 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
