Description
The Bently Nevada 3300/16 XY/Gap Dual Vibration Monitor is a specialized rack-mounted module designed for the 3300 Monitoring System. It provides simultaneous measurement of radial shaft vibration and probe gap voltage. By continuously monitoring these parameters against user-defined alarm setpoints, the module provides critical protection for rotating machinery, including industrial turbines, centrifugal compressors, and large pumps. This unit supports predictive maintenance strategies by delivering reliable, high-resolution displacement and vibration data to the control system.
Features
- Dual-channel monitoring capability for XY vibration and gap voltage.
- Continuous signal processing with integrated Alert and Danger alarm logic.
- Compatible with standard Bently Nevada proximity probe and Proximitor sensor systems.
- Front-panel LED status indicators for OK, Bypass, Alert, and Danger conditions.
- Configurable output options including 4-20 mA, 1-5 VDC, and 0 to -10 VDC signals.
- Designed for seamless integration into existing 3300 series rack environments.
Applications
- Radial shaft vibration monitoring for fluid-film bearing machines.
- Proximity probe gap voltage monitoring for machine health diagnostics.
- Critical asset protection in petrochemical, power generation, and oil and gas facilities.
- Integration with DCS or PLC systems for automated machinery shutdown and data logging.

Installation Guidelines
- Ensure the 3300 rack is powered down before inserting or removing the monitor module to prevent electrical damage.
- The module must be installed in a clean, dry environment within the specified temperature range.
- Use shielded twisted-pair cabling for all transducer inputs to minimize EMI/RFI interference.
- Ensure proper grounding of the 3300 rack system per Bently Nevada installation manuals to maintain signal integrity.
- Verify that all field wiring is correctly terminated at the rack backplane before applying power.
- Confirm that the configuration switches/jumpers match the specific transducer and range requirements for the application.
FAQ
What is the primary function of the 3300/16 monitor?
