Product Description
The Bently Nevada 3500/42M-01-00 Proximitor Seismic Monitor is a sophisticated four-channel module designed for critical machinery condition monitoring. It accepts signals from proximity and seismic transducers and conditions them for accurate measurement of vibration, position, and acceleration. Its primary role is to safeguard equipment by comparing these measurements against user-defined alarm thresholds, ensuring proactive maintenance and operational safety.
Each pair of channels on the 3500/42M can be configured independently to monitor parameters such as radial vibration, REBAM, thrust position, eccentricity, shaft absolute, and more. Configurable through 3500 Rack Configuration Software, the monitor provides both real-time condition monitoring and data for analysis by maintenance teams.
