Product Description
The Bently Nevada 3500/42M-01-00 140734-02 Proximitor Seismic Monitor is a four-channel monitoring module designed to safeguard rotating machinery through continuous real-time analysis of vibration and position parameters. This monitor accepts inputs from proximity probes, accelerometers, and velocity sensors, conditioning these signals to output critical static values. These values are compared against configurable alert and danger setpoints for machinery protection and operational diagnostics.
Each channel can be configured independently in pairs using the 3500 Rack Configuration Software, supporting parameters like radial vibration, acceleration, thrust position, differential expansion, shaft absolute measurements, REBAM (Rolling Element Bearing Analysis Monitor), and more. Flexible output options, environmental endurance, and extensive diagnostic capabilities make the 3500/42M suitable for the most demanding industrial applications.
