Product Description
The Bently Nevada 3500/40M 143488-01 Proximitor Monitor is a four-channel machinery condition monitoring module designed to interface with proximity transducers. It conditions signals to measure radial vibration, thrust position, differential expansion, eccentricity, and REBAM parameters, while continuously comparing them against configurable alarm setpoints for reliable machinery protection. It supports flexible configuration through 3500 Rack Configuration Software, enabling channels to operate independently or in pairs for multiple monitoring functions.
