Downhole Pressure Transducer Series 211-37-520:
0-5,000 through 0-30,000 PSIA. This downhole transducer series is specifically designed for high temperature and high pressure applications where long-term stability is important.
The material used in our downhole sensor construction is compatible with H2S and other highly corrosive media. Instead of an o-ring, an Inconel 600 seal can be purchased and used for virtually maintenance-free, permanent high temperature/pressure transducer installations. Contact the factory for downhole pressure transducer drawings and details, or see below for specifications.
Since 1951, Paine Electronics has manufactured state-of-the-art precision pressure instrumentation for some of the world’s most vital technologies. Each Paine pressure/temperature transducer represents our unwavering commitment to reliability and innovation. The most accurate pressure instrumentation is ensured through rigorous testing and the most advanced materials (e.g. a high-resistance platinum RTD for greater sensitivity or advanced bonded strain gage technology for long-term stability and accuracy).
