3500/40M Proximitor® Monitor

Proximitor®

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.
