Bently Nevada 3500/42M Proximitor Seismic Monitor

The Bently Nevada 3500/42M Proximitor Seismic Monitor is a four-channel monitor that accepts input from proximity and seismic transducers. It conditions the signal to provide vibration and position measurements and compares the conditioned signals with user-programmable alarms.

The 3500/42M Proximitor Seismic Monitor:

• Protects machinery by continuously comparing monitored parameters against configured alarm setpoints to drive alarms.
• Communicates essential machine information to both operations and maintenance personnel.

You can program each channel using the 3500 Rack Configuration Software to monitor and report:

• Radial vibration
• REBAM
• Thrust position
• Acceleration
• Differential expansion
• Shaft absolute
• Eccentricity
• Circular acceptance region
• Velocity

The monitor channels are programmed in pairs and can perform up to two of the listed functions at a time. For example, Channels 1 and 2 can perform one function while channels 3 and 4 perform another or the same function.

Each channel, depending on configuration, typically conditions its input signal to generate various parameters called static values. You can configure alert setpoints for each active static value and danger setpoints for any two of the active static values.
