Product Overview
The Bently Nevada 3500/40M 140734-01 Proximitor Monitor is a four-channel monitoring module designed for machinery condition monitoring and protection. It works with proximity transducers to measure radial vibration, thrust position, differential expansion, eccentricity, and REBAM parameters. Using the 3500 Rack Configuration Svontware, users can configure each channel to perform up to two functions simultaneously, ensuring precise condition assessment and early fault detection in critical rotating machinery.
