Product Description
The Bently Nevada 3500/42M Proximitor Seismic Monitor is a four-channel module designed to monitor vibration, position, and seismic parameters in critical rotating machinery. It continuously compares measured parameters with programmable alarm thresholds to protect equipment and notify personnel of abnormal conditions. Each channel pair can be programmed independently to perform different monitoring functions simultaneously.
