Product Overview
The Bently Nevada 3500/40M 176449-01 Proximitor Monitor is a four-channel machinery protection and condition monitoring device. It processes signals from proximity transducers to measure vibration, position, and other key parameters, and compares them with configurable alarm setpoints. Designed for continuous monitoring, it delivers critical machine health information for operational and maintenance decisions. Channels are programmable in pairs, supporting multiple measurement functions simultaneously.
