Product Details

Standard 4-20mA 3051 Pressure Transmitter



The 3051 pressure transmitter is the only sensor in the world that USES H alloy sheath (patented technology), which achieves excellent cold and thermal stability when working. During working, the isolation diaphragm and filling fluid on the high and low pressure sides transfer the process pressure to the filling fluid, and then the filling fluid transfers the pressure to the sensing diaphragm in the sensor center.The difference in capacitance between the sensing diaphragm and the capacitor electrode is converted to the corresponding current, voltage or digital HART(high speed addressable remote transmitter data highway) output signal.
