Description
The Bently Nevada 3300/55-01-05-02-02-00-00-09-00 is a dedicated dual-channel velocity monitoring module engineered for the 3300 series machinery protection platform. This unit is specifically calibrated to interface with Velomitor piezo-velocity sensors, providing continuous casing vibration monitoring for critical rotating equipment such as industrial turbines, centrifugal compressors, large motors, and pump sets. The module processes incoming signals to provide reliable velocity measurements and automated alarm logic.
Features
- Dual independent velocity monitoring channels for redundant or multi-point machinery protection.
- Optimized for direct integration with Velomitor piezo-velocity sensor inputs.
- Equipped with dual relay outputs for standardized Alert and Danger alarm setpoint management.
- Integrated proportional 4-20 mA output for seamless data transmission to external PLCs or DCS control systems.
- Designed for high-reliability operation within the Bently Nevada 3300 rack-based environment.
Applications
This monitor is essential for plant-floor machinery protection, serving as a primary safeguard against excessive casing vibration. Typical installations include:
- Turbine-generator sets and steam turbines.
- Process gas compressors and air compressors.
- Large-scale industrial motor and pump assemblies.
- Balance-of-plant rotating machinery requiring continuous velocity monitoring.

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 designated rack slot to ensure proper backplane connectivity.
- Use shielded cabling for sensor inputs to minimize electromagnetic interference (EMI) and signal noise.
- Confirm proper grounding of the 3300 rack system to maintain signal integrity and safety compliance.
- Ensure adequate ventilation around the rack assembly to maintain ambient operating temperatures within the 0 degC to +60 degC range.
FAQ
Q: Does this module require external barriers for hazardous environments?
A: The suffix code 00 in the barrier position indicates this specific unit is configured without intrinsic safety barriers. Please verify your facility's safety requirements before installation.
Q: Can this module be used with non-Bently Nevada sensors?
A: This module is specifically designed for Velomitor piezo-velocity sensors. Using incompatible sensors may result in inaccurate readings or failure to trigger alarm setpoints.
