The BENTLY 3500/42-01-00  Proximitor/Seismic Monitor is a 4-channel monitor that accepts
input from proximity and seismic transducers, conditions the signal to provide
various vibrations and position measurements, and compares the conditioned
signals with user-programmable alarms. The user can program each channel of
the 3500/42M using the 3500 Rack Configuration Software to perform any of the
following functions:
• Radial Vibration
• Thrust Position
• Differential Expansion
• Eccentricity
• REBAM*
• Acceleration
• Velocity
• Shaft Absolute
• Circular Acceptance Region

The primary purpose of the BENTLY 3500/42-01-00  monitor is to provide:
1. Machinery protection by continuously comparing monitored parameters
against configured alarm setpoints to drive alarms.
2. 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”. The user can configure Alert
setpoints for each active static value and Danger setpoints for any two of the
active static values.
