Product Description
The Bently Nevada 3500/40 140734-01 Proximitor Monitor is a four-channel monitoring module designed to accept inputs from proximity transducers. It processes these signals to measure vibration, position, and related parameters, and compares them against user-defined alarm limits. This monitor offers flexible channel configuration to perform functions such as radial vibration, thrust position, eccentricity, differential expansion, and REBAM (Rolling Element Bearing Analysis Monitor). It provides continuous machinery protection and operational insights for both maintenance and operations teams.
