Bently Nevada 3500/42 125672-02 Proximitor Seismic Monitor

Overview

The 3500/42 Proximitor®/Seismic Monitor is a versatile four-channel device designed for machinery protection and monitoring. It utilizes inputs from Proximitor and Seismic Transducers to trigger alarms and provide critical vibration data.

Technical Specifications

• Monitoring Functions:

  • Radial Vibration
  • Thrust Position
  • Eccentricity
  • Differential Expansion
  • Acceleration
  • Velocity

• Alarm Setpoints:

  • Configured via 3500 Rack Configuration Software
  • Continuous comparison of current machine vibration against setpoints
  • Active proportional values can have configured danger setpoints

• Configuration:

  • Ships unconfigured, allowing flexibility for various applications
  • Can be integrated into a 3500 rack for monitoring function setup

• TMR Configuration:

  • Installation: TMR monitors and Proximitor/Seismic TMR I/O Modules must be grouped in threes
  • Voting Mechanisms:
    • TMR Relay Module Voting: 2 out of 3 method where two monitors must agree before an alarm output is activated
    • Comparison Voting: Compares proportional value outputs among monitors; discrepancies beyond a specified limit trigger an entry in the System Event List

• Input Configuration Types:

  • Bussed Configuration: Uses a single non-redundant transducer's signal for all TMR modules through a Bussed External Termination Block
  • Discrete Configuration: Requires three redundant transducers per measurement location, each connected to separate External Termination Blocks
