Description

The Bently Nevada 3300/16 Dual Vibration XY/GAP Monitor is a rack-mounted module within the 3300 Series monitoring system. It is engineered to provide simultaneous measurement of radial shaft vibration (XY) and probe gap voltage. This dual-channel monitoring capability is essential for the protection of critical rotating machinery, including turbines, compressors, and pumps, by facilitating the early detection of mechanical issues such as bearing wear, shaft misalignment, and rotor rubs.

Features

• Dual-channel configuration for simultaneous XY vibration and gap monitoring.
• Compatible with standard proximity probe (Proximitor) transducer inputs.
• Integrated relay outputs for Alert and Danger alarm conditions.
• Proportional 4-20 mA outputs for integration with external control or data acquisition systems.
• Front-panel LED status indicators for OK, Bypass, Alert, and Danger conditions.
• Continuous signal processing and comparison against configurable alarm setpoints.

Applications

This monitor is designed for use in industrial environments where continuous vibration monitoring is required for rotating equipment. It is commonly deployed in power generation, petrochemical processing, and oil and gas facilities to ensure machinery health and prevent catastrophic failure.

Technical Specifications

Installation Guidelines

• Ensure the 3300 rack is properly grounded before installing the module.
• Handle the module using standard ESD (Electrostatic Discharge) protection practices.
• Power down the rack or ensure the slot is bypassed before inserting or removing the monitor module to prevent electrical damage or unintended alarm trips.
• Verify that all field wiring for proximity probes is shielded and routed away from high-voltage or high-EMI sources to maintain signal integrity.
• Ensure adequate ventilation in the rack cabinet to maintain ambient temperatures within the specified operating range.

FAQ

What does the 3300/16 monitor measure?

The 3300/16 is designed to measure radial shaft vibration (XY) and probe gap voltage simultaneously, providing critical data for monitoring the mechanical condition of rotating shafts.

Is this module compatible with standard proximity probes?

Yes, this specific model (order code 02 for transducer input) is configured to interface directly with standard Bently Nevada proximity probe systems.

What do the relay outputs indicate?

The relay outputs are configured to trigger based on Alert and Danger alarm setpoints, allowing the system to initiate automated shutdowns or operator notifications when vibration levels exceed safe thresholds.
