The Bently Nevada 3300/16-14-01-01-00-00-00 is a dual-channel vibration monitoring module designed for the 3300 Series machinery protection system. This unit provides continuous, high-speed monitoring of radial shaft vibration, making it essential for the protection of critical rotating assets such as industrial pumps, compressors, and turbines. By processing signals from proximity probes, the module detects mechanical anomalies like shaft misalignment, rotor imbalance, and bearing degradation in real-time.

Features

• Dual-channel architecture for independent vibration signal processing.
• Continuous comparison of input signals against user-defined Alert and Danger setpoints.
• Integrated relay outputs for automated machinery shutdown or alarm annunciation.
• Proportional 4–20 mA output signals for integration with external PLC or DCS systems.
• Front-panel LED status indicators for quick diagnostics of OK, Bypass, Alert, and Danger states.
• Optimized for use with standard Bently Nevada Proximitor sensor inputs.

Applications

This module is widely utilized in heavy industrial environments to safeguard rotating equipment. Typical applications include monitoring radial shaft displacement on large steam turbines, centrifugal compressors, and high-speed gearboxes to ensure operational safety and prevent catastrophic mechanical failure.

Technical Specifications

Installation Guidelines

• Ensure the 3300 series rack is powered down before inserting or removing the module.
• Handle the module using proper ESD (Electrostatic Discharge) precautions to prevent damage to internal circuitry.
• Verify that all field wiring is routed away from high-voltage cables or sources of significant electromagnetic interference (EMI).
• Ensure proper grounding of the rack assembly to maintain signal integrity for low-level vibration data.
• Check that the proximity probe cabling is correctly shielded and terminated according to Bently Nevada wiring standards.

FAQ

What is the primary function of the 3300/16 module?
The module monitors radial shaft vibration on two independent channels and triggers alarms if vibration levels exceed established thresholds.

Can this module interface with a PLC?
Yes, the module provides proportional 4–20 mA outputs that can be wired directly into a PLC or DCS for remote monitoring and data logging.

What do the relay outputs on this module indicate?
The relays are typically configured to trigger based on Alert and Danger setpoints, allowing the system to initiate warnings or automated emergency shutdowns.
