Product Overview
The Bently Nevada 3500/40M Proximitor Monitor is a four-channel vibration and position monitoring module designed for use with proximity transducers. It processes input signals, provides various static and dynamic measurements, and compares them to user-defined alarm thresholds for reliable machinery protection. It supports functions such as radial vibration, thrust position, eccentricity, differential expansion, and REBAM (Rolling Element Bearing Analysis Measurement).
