Description
DPT-CR-MOD measures the pressure difference between the cleanroom and the anteroom and sends the information to the automation system via Modbus to maintain optimal conditions in the cleanroom. DPT-CR-MOD is connected to the Siro indoor air quality transmitter that measures relative humidity and temperature. Siro sends the information to DPT-CR-MOD that shows it on its display, together with differential pressure measurement.
