Differential Pressure Transmitter



The model PT124B-3501 differential pressure transmitter can be used to measure liquid, gas, or stem flow, as well as liquid level, density and pressure. It outputs a 4 to 20mA DC HART signal corresponding to the measured pressure differential. The model PT124B-3501 also features remote setup and monitoring though communication with the model RST375 TERMINAL or RSM100 Modem.
