Description
Description
The Bently Nevada 3300/55 Dual Velocity Monitor is a specialized rack-mount module designed for the 3300 Series machinery protection system. This unit provides continuous monitoring of casing vibration velocity by utilizing Velomitor piezo-velocity sensors. It features two independent channels that process vibration signals to ensure critical machinery protection through real-time comparison against user-defined alarm setpoints.
Features
- Dual independent velocity monitoring channels for comprehensive casing vibration analysis.
- Integrated relay outputs configured for Alert and Danger alarm conditions to facilitate automated machinery shutdown or operator notification.
- Proportional 4-20 mA outputs provide direct interface capability with external data acquisition or control systems.
- Front-panel LED indicators display operational status, including OK, Bypass, Alert, and Danger states for rapid diagnostic assessment.
- Configured with intrinsic safety barrier support for reliable operation in hazardous industrial environments.
Applications
This module is typically deployed in power generation, petrochemical, and heavy industrial facilities where casing vibration monitoring is essential for predictive maintenance and asset protection. It is designed to interface directly with rotating equipment sensors to detect mechanical instability before failure occurs.
