Bently Nevada 125388-01 Proximitor Seismic Monitor

Description

The Proximitor Seismic Monitor is a sophisticated four-channel monitoring device designed to safeguard industrial machinery. It continuously compares monitored parameters against user-defined alarm setpoints to trigger alerts and communicates critical machine data to both operations and maintenance teams. Capable of accepting inputs from proximity and seismic transducers, the monitor conditions these signals to deliver precise vibration and position measurements. Users can configure each channel via the 3500 Rack Configuration Software to track various parameters, including radial vibration, thrust position, and more.
