3500/40M Proximitor® Monitor
Bently Nevada™ Asset Condition Monitoring
Description
The 3500/40M Proximitor® Monitor is a 4-channel monitor that accepts input
from Bently Nevada proximity transducers, conditions the signal to provide
various vibration and position measurements, and compares the conditioned
signals with user-programmable alarms. The user can program each channel of
the 3500/40M with the 3500 Rack Configuration Software to perform any of the
following functions:
• Radial Vibration
• Thrust Position
• Differential Expansion
• Eccentricity
• REBAM®
Note: The monitor channels are programmed in pairs and can perform up to two of these
functions at a time. Channels 1 and 2 can perform one function, while channels 3 and 4
perform another (or the same) function.
The primary purpose of the 3500/40M monitor is to provide:
1. Machinery protection by continuously comparing monitored parameters
against configured alarm setpoints in order to drive alarms.
2. Essential machine information for both operations and maintenance
personnel.
Each channel, depending on configuration, typically conditions its input signal
into various parameters called “static values”. The user can configure alert
setpoints for each 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 pair configured for REBAM.
The top graph assumes that both channels of the channel pair are enabled. The bottom graph assumes that only one
channel of a channel pair is enabled. The maximum speed depends on the number of rolling elements in the bearing.
The graph assumes that the rotor low-pass filter corner is set at 3.2X the shaft speed and the spike high-pass filter
corner is set at 4X the element pass frequency for the outer race (BPFO).
