The Bently Nevada 3500/40M Proximitor Monitor is a four-channel monitoring module designed to accept inputs from proximity transducers, condition vibration and position signals, and compare these signals to user-configured alarm setpoints. It supports multiple measurement functions including radial vibration, thrust position, differential expansion, eccentricity, and REBAM. This model combines robust machinery protection with detailed diagnostic information for operations and maintenance teams.
