Product Description
The Bently Nevada 3500/40 Proximitor Monitor is a four-channel machinery condition monitoring device designed to accept input from proximity transducers, condition the signals, and provide precise vibration and position measurements. It supports multiple measurement types, including radial vibration, thrust position, eccentricity, differential expansion, and REBAM (Rolling Element Bearing Analysis Method). Each channel is fully programmable via the 3500 Rack Configuration Ssurtware and allows independent configuration for optimal machine protection. This model combination includes the 176449-01 main monitor module and the 135489-04 I/O module with internal barriers and terminations, enabling use in hazardous environments.
