Bently Nevada* Ast Condition Monitoring 3500/42M Proximitor */Seismic Monitor
Specifications and Ordering Information
Part Number 143694-01
Rev. H (12/09)
Description The 3500/42M Proximitor*/Seismic Monitor is a 4-channel monitor that accepts input from proximity and ismic transducers, conditions the signal to provide various vibration and position measurements, and compares the conditioned signals with ur-programmable alarms. The ur 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
Note: The monitor channels are programmed in pairs and can perform up to two of the 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 purpo of the 3500/42M monitor is to provide:
1. Machinery protection by continuously comparing monitored parameters
against configured alarm tpoints to drive alarms. 2. Esntial machine information for both operations and maintenance
小马过河托福personnel. Each channel, depending on configuration, typically conditions its input signal to generate various parameters called “static values”. The ur can configure Alert tpoints for each active static value and Danger tpoints for any two of the active static values.
