Description

The Bently Nevada 3300/20 Dual Thrust Monitor is a rack-mounted module designed for precise axial thrust position measurement in critical rotating machinery, including turbines and compressors. This module provides continuous monitoring of axial displacement, allowing for early detection of bearing wear or mechanical failure to support predictive maintenance strategies and minimize unplanned downtime.

Features

  • Dual-channel axial thrust monitoring configuration.
  • Continuous comparison of measured parameters against user-defined Alert and Danger alarm setpoints.
  • Integrated relay outputs for automated alarm and trip logic.
  • Front-panel LED indicators providing status for OK, Bypass, Alert, and Danger conditions.
  • Configured for compatibility with standard proximity probes and Proximitor sensors.

Applications

This monitor is specifically engineered for use within the Bently Nevada 3300 monitoring system, serving as a primary protection component for large rotating equipment where axial position integrity is critical to machine health.

Technical Specifications

Installation Guidelines

  • Ensure the 3300 rack is powered down before inserting or removing the monitor module to prevent electrical damage.
  • Verify that the module is correctly seated in the rack slot to ensure proper backplane communication.
  • Use shielded cabling for all transducer inputs to minimize electromagnetic interference (EMI).
  • Ensure proper grounding of the 3300 rack system in accordance with standard industrial instrumentation practices.
  • Handle with care to prevent electrostatic discharge (ESD) damage to the internal circuitry.

FAQ

What does the 11 suffix represent in this model?

The 11 suffix indicates the measurement option configured for dual-channel thrust monitoring, which allows the module to process two axial displacement signals simultaneously.

Is this module compatible with standard proximity probes?

Yes, the 01 transducer input option is specifically configured to accept signals from standard proximity probes paired with Proximitor sensors.
