Product Overview

The Bently Nevada 3500/77M (140734-07) is a specialized 4-channel monitor integrated within the 3500 Machinery Protection System. While the "77M" series is frequently associated with temperature monitoring, the 140734-07 specifically refers to the Reciprocating Cylinder Pressure Monitor variant. This module is engineered for the diagnostic and protective requirements of reciprocating compressors. It captures high-speed cylinder pressure data to calculate key performance metrics such as peak pressure, discharge pressure, and suction pressure. By monitoring these variables in real-time, the module protects against mechanical overloads and optimizes the thermal efficiency of reciprocating units.
