The diaphragm seal of PT124B-3503 differential 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. Specification Measurement parameter: Differential pressure, liquid level Measurement range: 0-1KPa-2MPa Accuracy: +/-0.1% Wetted parts materialSS316L, Hastelloy C, tantalum Output: 2-wire 4-20mA, HART communication optional, linear output or square root output available Ambient temperature limited Lowest: depending on the filled liquid Highest: 85℃ -20~65℃ (with LCD display, fluorine rubber O-ring) Temperature limited: -30~400℃ Protection grade: IP67 Electrical connector: M20*1.5 cable sealing buckle, terminal suitable for 0.5-2.5mm2 cable Process connector: 7/16 female at the low pressure, compatible with ANSI or DIN at high pressure. Directly install.
