The Bently Nevada 3300/16-12-01-00-00 is a specialized dual-channel vibration monitor engineered for the 3300 Series machinery protection system. This module provides critical monitoring of radial shaft vibration, specifically utilizing two independent channels to track machine health in industrial environments such as turbines, compressors, and centrifugal pumps.

Features

  • Dual-channel configuration for comprehensive XY shaft vibration monitoring.
  • Integrated Proximitor sensor compatibility for precise proximity probe signal processing.
  • Standard relay outputs providing dedicated Alert and Danger alarm signaling.
  • Front-panel LED status indicators for real-time monitoring of OK, Bypass, Alert, and Danger states.
  • Proportional 4–20 mA output signals for integration with external control or data acquisition systems.

Applications

This module is typically deployed in critical rotating machinery protection schemes where continuous, high-reliability monitoring is required to prevent catastrophic failure. It is widely utilized in power generation, petrochemical processing, and oil and gas infrastructure to monitor vibration trends and trigger protective shutdowns when setpoints are exceeded.

Installation Guidelines

  • Ensure the 3300 rack is powered down before inserting or removing the monitor module to prevent electrical damage.
  • Verify that all field wiring for proximity probes is properly shielded and routed away from high-voltage or high-EMI noise sources.
  • Confirm proper grounding of the 3300 rack chassis to a clean earth ground to minimize signal interference.
  • Maintain adequate ventilation around the rack to keep ambient temperatures within the specified -30 degC to +65 degC range.
  • Use appropriate ESD precautions when handling the module to protect internal circuitry.

FAQ

Does this module support proximity probes?

Yes, the 3300/16-12-01-00-00 is explicitly configured to interface with standard proximity probes (Proximitor sensors) to measure shaft vibration.

What type of alarms does this monitor provide?

The unit provides standard relay outputs for both Alert and Danger conditions, allowing for tiered protection logic based on your machinery's specific vibration thresholds.
