The Bently Nevada 3300/16 Dual Vibration Monitor is a specialized rack-mounted module engineered for the 3300 Series monitoring system. It provides precise, continuous measurement of radial shaft vibration using two independent channels. This specific model, identified by order code 3300/16-14-01-01-00-00-00, is designed to support critical machinery protection strategies in industrial environments, including large rotating equipment such as turbines, compressors, and centrifugal pumps.

Features

  • Dual-channel input configuration optimized for radial shaft vibration monitoring.
  • Integrates seamlessly with Proximitor sensors for high-accuracy proximity measurement.
  • Provides proportional 4-20 mA outputs for integration with external control systems or data acquisition.
  • Features dedicated relay outputs to trigger Alert and Danger alarms based on pre-configured setpoints.
  • Includes front-panel LED indicators for real-time status monitoring, including OK, Bypass, Alert, and Danger states.

Applications

This module is intended for use in condition monitoring systems where early detection of mechanical degradation is required. It is commonly deployed to identify issues such as shaft misalignment, rotor imbalance, and bearing wear before they lead to catastrophic equipment failure.

Installation Guidelines

  • Ensure the 3300 rack is powered down before inserting or removing the monitor module to prevent electrical damage.
  • Handle the module using standard ESD-safe practices to protect sensitive internal circuitry.
  • Verify that all field wiring for proximity probes and relay outputs is properly shielded to minimize EMI interference.
  • Ensure the module is fully seated in the rack slot and that the front-panel locking mechanism is engaged.
  • Verify alarm setpoints via the configuration interface before placing the machinery into active service.

FAQ

What does the 14 in the model number signify?

The 14 indicates the measurement option, specifically a dual vibration channel configuration with extended monitoring capabilities.

Is this module compatible with standard Proximitor sensors?

Yes, this unit is configured for standard proximity probe (Proximitor) inputs as specified in the 01 transducer input option.

What is the primary function of the relay outputs?

The relay outputs are designed to actuate when vibration levels exceed programmed Alert or Danger thresholds, providing a hard-wired interface for emergency shutdown or operator notification systems.
