Room differential pressure transmitter with RS-485 communication. It has two inputs for a temperature and humidity transmitter. It displays pressure, temperature, and humidity values simultaneously on its screen.
The DPT-CR-MOD is a differential pressure transmitter specifically designed for cleanroom monitoring. In addition to differential pressure, the device also monitors temperature and relative humidity.
A 0–10 V voltage signal from an external temperature and humidity transmitter (e.g., RTX-RH) can be connected to the device's input. In this case, the three measured values (differential pressure, relative humidity, and temperature) can be displayed simultaneously.
Alternatively, a passive temperature sensor can be connected to the input terminal. The DPT-CR-MOD is compatible with the Modbus serial communication protocol.
