Bently Nevada PWA-140072-04D Differential Expansion Thrust Monitor

The Bently Nevada PWA-140072-04D Differential Expansion Thrust Monitor is a four-channel 3500/45 Position Monitor module designed to supervise turbine and other rotating machinery. It accepts inputs from the 3300XL Proximitor transducers, Rotary Position Transducers (RPTs), and AC or DC LVDTs, and provides measurements for Axial (thrust) Position, Differential Expansion (single ramp, dual ramp, or complementary), Case Expansion, and Valve Position. Integrated into the 3500 Machinery Protection System, it conditions the signals, compares them against programmable alarms, and helps detect thrust growth and differential expansion to protect bearings and related components in turbine systems as part of Bently Nevada's Turbine Supervisory Instrumentation (TSI) suite.
