Description The 3500/42M Proximitor*/Seismic Monitor is a 4-channel monitor that accepts input from proximity and seismic 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 3500/42M 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 3500/42M 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.
