The Bently Nevada 3300/16 XY/Gap Dual Vibration Monitor is a critical component of the 3300 Monitoring System, designed to provide continuous, reliable protection for rotating machinery. This module monitors radial vibration (XY) and gap (position) measurements, providing essential data for assessing the mechanical health of turbines, compressors, and pumps. It processes signals from Proximitor sensors to detect excessive vibration levels and shaft displacement, triggering alarms or trip functions when thresholds are exceeded.
Features
Dual-channel configuration for XY vibration and gap monitoring.
Compatible with 3300 8 mm, 3300 XL 8 mm, and 7200 5 mm/8 mm Proximitor sensors.
Configured for 200 mV/mil transducer sensitivity.
Integrated trip multiply function (3X) for startup and transient analysis.
Equipped with hermetically-sealed alarm relays for high reliability in industrial environments.
CSA/NRTL/C agency approval for hazardous location compliance.
Applications
This monitor is widely utilized in power generation, petrochemical, and oil and gas industries. It is specifically engineered for monitoring sleeve-bearing machines where radial vibration and shaft position are critical indicators of machine integrity.

Installation Guidelines
Ensure the 3300 rack power is disconnected before inserting or removing the module to prevent electrical damage.
Verify that the module is fully seated in the rack slot and that the front panel screws are tightened to ensure proper grounding and mechanical stability.
Use shielded twisted-pair cabling for all transducer inputs to minimize electromagnetic interference (EMI).
Ensure proper routing of signal cables away from high-voltage power lines or high-frequency switching equipment.
Handle the module using ESD-safe practices to protect internal circuitry from electrostatic discharge.
