Description
Description
The Bently Nevada 3300/16 Dual Vibration XY/GAP Monitor is a specialized rack-mounted module engineered for the 3300 Series monitoring system. It provides high-reliability, continuous monitoring of radial shaft vibration in two planes (XY) while simultaneously tracking probe gap voltage. This dual-channel functionality is essential for protecting critical rotating machinery, including industrial turbines, centrifugal compressors, and high-performance pumps, by identifying mechanical issues like shaft misalignment, bearing degradation, or rotor rubs.
Features
- Dual-channel input configuration tailored for proximity probe (Proximitor) integration.
- Real-time processing of dynamic vibration signals and proportional 4–20 mA outputs for external data logging or PLC integration.
- Integrated alarm logic with dedicated relay outputs for Alert and Danger status conditions.
- Front-panel LED status indicators providing instant visual feedback for OK, Bypass, Alert, and Danger states.
- Rugged construction suitable for demanding industrial environments.
Applications
This monitor is designed for use in critical machinery protection systems where precise radial vibration and gap measurement are required. It is commonly deployed in power generation, petrochemical processing, and oil and gas production facilities to prevent catastrophic equipment failure through early detection of mechanical anomalies.

Installation Guidelines
- Ensure the 3300 rack is properly grounded before installing the module to prevent electrical noise interference.
- Handle the module using standard electrostatic discharge (ESD) precautions.
- Always power down the rack or ensure the slot is bypassed before inserting or removing the monitor to prevent accidental relay actuation or signal disruption.
- Use shielded cabling for all transducer inputs to maintain signal integrity in high-EMI industrial environments.
- Verify that the configuration switches and jumpers match your specific machine requirements before final commissioning.
FAQ
What does the 3300/16 monitor measure? This module measures radial shaft vibration in two planes (XY) and the gap voltage (probe gap) for proximity sensors.
Is this module compatible with existing 3300 series racks? Yes, the 3300/16 is designed for full integration within the standard Bently Nevada 3300 rack system.
What do the Alert and Danger relays do? These relays provide hard-wired outputs that trigger based on pre-configured vibration thresholds, allowing the system to initiate alarms or automatic machine shutdowns.
