Bently Nevada 3300/16-12-01-01-00-00-00 Dual Vibration Monitor Module

Bently Nevada 3300/16-12-01-01-00-00-00 Dual Vibration Monitor Module

The Bently Nevada 3300/16-12-01-01-00-00-00, also cataloged as the 3300/16 Dual Vibration Monitor, operates as a dedicated hardware component for the continuous, online monitoring of two independent radial vibration channels and shaft position within machinery protection systems.

Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The 3300/16 monitor is engineered to provide high-precision rotor dynamics data by processing raw signals from two proximity probes. This facilitates real-time XY vibration measurement alongside average shaft position tracking. The system requires rigorous gap voltage validation to ensure that sensors operate within the linear measurement range, typically targeting a center gap of -10 VDC. The internal architecture includes cross-talk suppression circuitry to isolate input channels, preventing signal interference in high-density rack configurations. By providing integrated radial position gap alarms, this module effectively supersedes the 3300/15 monitor, enabling more robust detection of shaft misalignment and bearing degradation.

Frequently Asked Questions

Q: Is this monitor compatible with existing 3300/15 installations?A: Yes, the 3300/16 is designed as a direct functional replacement for the 3300/15, providing identical vibration monitoring capabilities with the added benefit of radial position gap alarming.

Q: Does the module support field-adjustable relay logic?A: Yes, the relay contacts can be configured via the 3300 system interface to open or close based on the Alert, Danger, or OK status of either channel to suit specific site shutdown logic.

Field Installation Guidelines

• System Integration: Ensure the module is installed in a properly grounded 3300 series instrument rack. Verify backplane connector pin alignment before seating to avoid mechanical damage.
• Sensor Cabling: Connect proximity probe signals using shielded coaxial cabling. Terminate the shield at the rack common ground to maintain a low noise floor for sensitive vibration data.
• Gap Validation: Prior to machine start-up, verify the physical probe gap and confirm the output voltage at the Proximitor terminals falls within the nominal linear monitoring range.
• Logic Verification: After installation, utilize the monitor interface to trigger a test of the Alert and Danger relay contacts to ensure communication with the external protection system is established.
