PXT-K Series

The PXT-K Series pressure transmitters are state-of-the-art instruments providing 4-20 mA output.

Each Piezoresistive Pressure Transmitter contains a transducer comprised of a piezoresistive silicon chip mounted on a glass-metal feed-through 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 comply with NACE MR0175. PXT-K Series Pressure Transmitters can be used in applications such as compressors, engines, process control, liquid level and pumps.
