The Murphy -30”HG to +30PSI Pressure Transmitter PXT-K-30V30 is a state-of-the-art instrument providing 4-20 mA output. This pressure transmitter is a two wire type with flying lead connection and contains a transducer comprised of a piezoresistive silicon chip mounted on a glass-metal feedthrough header welded into a stainless steel housing and filled with silicone oil; the very thin laser-welded stainless steel isolation-diaphragm completes the front side. Media pressure is transferred from the stainless steel isolation-diaphragm, via the oil inside the cell, to the silicon measuring chip. This construction, combined with the advanced internal signal conditioning circuitry, results in a rugged instrument with extremely small temperature error and class-leading EMI/RFI resistance.

The enclosure and all wetted parts are made of 316L stainless steel to meet NACE MR01-75. Applications: PXT-K Series Pressure Transmitters can be used in applications such as Compressors, Engines, Process Control, Liquid Level and Pumps.
