BENTLY 3500/40M（140734-01）

Description

Description
The 3500/40M Proximitor Monitor is a four-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:
l Radial
vibration
l Eccentricity l REBAM
l Thrust
position
l Differential
expansion
The primary purpose of the 3500/40M Proximitor Monitor is to
provide the following:
l Machinery protection by continuously comparing
monitored parameters against configured alarm
setpoints to drive alarms
l Essential machine information for both operations and
maintenance personnel
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.
