FEATURES Communication: RS-485 Modbus (RTU) Accuracy (from applied pressure): (model 2500)Pressure < 125 Pa = 1 % + ±2 Pa Zero point calibration: via Modbus or by pushbutton
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. The AHU model that includes an air flow transmitter has been designed especially for ventilation units.
