Bently Nevada Machinery Condition Monitoring

143694 Rev. AC

Description
The 3500/42M Proximitor Seismic Monitor:llProtects machinery by continuously comparing
monitored parameters against configured alarm
setpoints to drive alarms.
Communicates essential machine information to both
operations and maintenance personnel.

The 3500/42M Proximitor Seismic Monitor is a four-channel
monitor that accepts input from proximity and seismictransducers. It conditions the signal to provide vibration andposition measurements and compares the conditioned
signals with user-programmable alarms.
You can program each channel using the 3500 Rack
Configuration Software to monitor and report:- Radial vibration- REBAM- Acceleration- Differential expansion- Eccentricity- Circular acceptanceregion- Thrust
position- Shaft
absolute- 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, typicallyconditions its input signal to generate various parameters
called static values. You can configure alert setpoints foreach active static value and danger setpoints for any two of
the active static values.

REBAM Channels
The following graphs show the maximum machine speed allowed for a monitor channel pairconfigured for REBAM. The maximum speed depends on the number of rolling elements in the bearing.
The graphs are generated with the following assumptions:ll

The rotor lowpass filter corner is set at 3.2 times the shaft speed.
The spike highpass filter corner is set at four times the element pass frequency for the outer race
(BPFO).
