Description
The 3500/40M Proximitor Monitor is a four-channel monitor designed to accept input from Bently Nevada proximity transducers. It conditions the signals to provide vibration and position measurements, then compares the conditioned signals against user-programmable alarms. This monitor is versatile, and each channel can be programmed with 3500 Rack Configuration Software to perform various functions, such as:
- Radial vibration
- Thrust
- Eccentricity
- Differential expansion
- REBAM (Rotor bar vibration monitoring)
