The Bently Nevada 3300/15 Dual Vibration Monitor is a rack-mounted module within the legacy 3300 Series monitoring system. It is engineered to provide continuous, high-reliability monitoring of radial shaft vibration across two independent channels. By processing signals from proximity probes, the module detects mechanical anomalies such as shaft imbalance, misalignment, and bearing degradation in rotating machinery like turbines, compressors, and pumps.
Features
Dual-channel vibration monitoring for comprehensive radial shaft analysis.
Integrated signal processing for Proximitor sensors.
Continuous comparison of vibration levels against user-defined Alert and Danger setpoints.
Front-panel LED status indicators for OK, Bypass, Alert, and Danger conditions.
Proportional 4-20 mA outputs for integration with external DCS or PLC systems.
Standard relay outputs for automated machinery protection and shutdown logic.
Applications
This module is designed for critical asset protection in industrial environments, including power generation, oil and gas, and petrochemical processing. It is typically deployed in 3300 Series racks to monitor large rotating equipment where early fault detection is essential for preventing catastrophic failure.

Installation Guidelines
Ensure the 3300 rack is powered down before inserting or removing the monitor module to prevent electrical damage.
Handle the module using proper ESD (Electrostatic Discharge) precautions to protect sensitive internal circuitry.
Verify that all field wiring for proximity probes is shielded and properly grounded to minimize EMI/RFI interference.
Ensure the module is fully seated in the rack slot and the front-panel locking mechanisms are secured.
Configure alarm setpoints and scaling via the module interface to match the specific mechanical requirements of the monitored machine.
