The Bently Nevada 3300/55 Dual Velocity Monitor is a specialized rack-based module engineered for the 3300 Series monitoring system. This unit provides continuous, high-reliability casing vibration velocity measurements by interfacing with Velomitor piezo-velocity sensors. It is designed to protect critical rotating machinery, such as pumps, compressors, turbines, and motors, by monitoring vibration levels against pre-configured Alert and Danger setpoints.
Features
- Dual independent velocity measurement channels for comprehensive machine protection.
- Optimized for integration with Velomitor piezo-velocity transducer inputs.
- Equipped with dual relay outputs to facilitate automated alarm and shutdown sequences.
- Integrated LED status indicators for real-time monitoring of OK, Bypass, Alert, and Danger states.
- Provides proportional 4-20 mA output signals for external system data acquisition.
Applications
This module is primarily deployed in industrial environments requiring precise vibration monitoring for rotating equipment. It serves as a critical component in condition monitoring systems to detect mechanical degradation or instability in turbines, large-scale motors, and centrifugal compressors.

Installation Guidelines
- Ensure the rack is powered down before inserting or removing the module to prevent electrical damage.
- Verify that the module is properly seated in the 3300 rack to ensure reliable backplane communication.
- Use shielded cabling for transducer inputs to minimize electromagnetic interference (EMI) in high-noise industrial environments.
- Maintain adequate ventilation within the cabinet to keep operating temperatures within the specified 0 to 60 degC range.
- Follow standard ESD (Electrostatic Discharge) precautions when handling the module to protect internal circuitry.
FAQ
What does the specific code 3300/55-01-04-02-02-00-00-05-00 represent?
This configuration code defines the specific hardware options for this unit, including its dual velocity channel setup, standard input barrier configuration, and relay output arrangement for machine protection.
Is this module compatible with other Bently Nevada systems?
The 3300/55 is specifically designed for the 3300 Series monitoring rack. It is not directly compatible with the newer 3500 series racks without appropriate system migration hardware.
