Description
The Bently Nevada 3500/42M Proximitor Seismic Monitor is a high-performance, four-channel module engineered for continuous condition monitoring and machine protection. It accepts signals from proximity probes and seismic transducers, processes them into precise vibration or position measurements, and compares those with user-configurable alarm thresholds. This model, paired with the 140471-01 Prox/Velom I/O module, ensures comprehensive data capture for radial vibration, thrust position, acceleration, differential expansion, eccentricity, shaft absolute, and more.
