Bently Nevada 3500/40M 140734-01+125680-01 Proximitor Monitor

Product Description

The Bently Nevada 3500/40M Proximitor Monitor is a four-channel machinery protection and condition monitoring module designed to work with proximity transducers. It processes vibration, position, and REBAM signals, providing accurate measurements and programmable alarms. Each channel can be configured independently using 3500 Rack Configuration Software to perform radial vibration, thrust position, differential expansion, eccentricity, or REBAM monitoring. The system ensures continuous protection by comparing monitored parameters against set alarm limits.
