Product Description
The Bently Nevada 3500/42M Proximitor Seismic Monitor is a four-channel module designed for continuous machinery protection and condition monitoring. It accepts input signals from proximity and seismic transducers, providing high-accuracy vibration, position, and acceleration measurements. By comparing these signals against user-defined alarm setpoints, the module ensures proactive maintenance and operational safety.
Equipped with advanced filtering, signal conditioning, and real-time diagnostics, the 3500/42M is essential in applications demanding precise vibration analysis, including turbines, compressors, motors, and gearboxes.
