Termékleírás
The DPT-Dual-MOD-AHU is a Modbus differential pressure transmitter designed specifically for air handling units (AHUs). Equipped with two pressure sensors featuring different measuring ranges, it simultaneously monitors differential pressure, airflow, and air velocity, making it ideal for fan and filter monitoring.
With Modbus RTU communication, two multifunction inputs, and a backlit display, the transmitter integrates seamlessly into building management systems (BMS). It is the perfect solution for HVAC applications, VAV systems, cleanrooms, filter monitoring, and airflow measurement.

The DPT-Dual-MOD-AHU features two integrated MEMS differential pressure sensors with measuring ranges of -250…2500 Pa and -700…7000 Pa for accurate monitoring of different pressure points. In addition to differential pressure, it also calculates airflow and air velocity.
The transmitter communicates via Modbus RTU over RS-485, with all measurement values transmitted digitally to the BMS. A backlit two-line display simultaneously shows pressure and airflow, while optional external temperature sensors connected to the two multifunction inputs can also be displayed.
The device operates on 24 Vac/Vdc, offers an IP54-rated housing, supports six pressure units and multiple airflow units, and is suitable for dry air and non-aggressive gases. Its robust design ensures reliable operation in demanding HVAC environments.
