Diaphragm Sealed Remote Differential Pressure Transmitter



The diaphragm seal of PT124B-3503 differential double flange mounting remote pressure transmitter is used to prevent medium from entering directly into the pressure-sensing assembly of the pressure transmitter. It is connected to the transmitter using capillary filled with fill fluid, such as silicon oil. The model PT124B-3503 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-3503 also features remote setup and monitoring though communication with the model RST375 TERMINAL or RSM100 Modem. PT124B-3503 with span range (non migration) is 0 to 1KPa to 2MPa, and the rated pressure of the liquid level flange is 1.6/4MPa, 6.4MPa, 10MPa, 150psi, 300psi or 600psi.
