165855 Cylinder Pressure Transducer

Intended specifically for use with the Bently Nevada 3500/77M Recip Cylinder Pressure Monitor when real-time, continuous monitoring of cylinder performance is required on reciprocating compressors. It is able to withstand the extreme temperatures and pressure cycling of reciprocating compressor cylinders while providing reliable measurements. It also incorporates innovative materials and construction techniques that allow it to survive in the harsh chemical environments typically encountered in reciprocating compressor applications, such as hydrogen sulfide (H2S). The transducer has undergone extensive testing and is unique in the industry, carrying a 3-year warranty. It is available with a number of adapters, allowing it to be used with many existing pressure indicator valves (e.g., Kiene* valves).
