3500/42M Proximitor Seismic Monitor
Datasheet
Bently Nevada Machinery Condition Monitoring
Description
The 3500/42M Proximitor Seismic Monitor:
l Protects machinery by continuously comparing
monitored parameters against configured alarm
setpoints to drive alarms.
l 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 seismic
transducers. It conditions the signal to provide vibration and
position 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:
143694 Rev. V
l Radial vibration l REBAM
l Thrust position l Acceleration
l Differential
expansion
l Eccentricity l Circular acceptance region
l 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.

External termination blocks cannot be used with Internal Termination I/O Modules. When
ordering I/O modules with external terminations, order the external termination blocks and
cable separately for each I/O module.

REBAM Channels
The following graphs show the maximum machine speed allowed for a monitor channel pair
configured for REBAM. The maximum speed depends on the number of rolling elements in the bearing.
The graphs are generated with the following assumptions:
l The rotor lowpass filter corner is set at 3.2 times the shaft speed.
l The spike highpass filter corner is set at four times the element pass frequency for the outer race
(BPFO).
