PXT Series Pressure Transmitters

4-20 mA Output Signal Piezoresistive Pressure Transmitter Corrosion Resistant Construction High Stability

New Part Number Announcement: Starting in September of 2026, as part of the regular CSA recertification process, new part numbers and model numbers have been created to reflect the new certification. The product specifications and pressure ranges remain the same. See table below.

The PXT-E-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-E-K Series Pressure Transmitters can be used in applications such as compressors, engines, process control, liquid level and pumps.
