Description

The Bently Nevada 3300/16 XY/GAP Dual Vibration Monitor is a rack-mounted module within the 3300 Series monitoring system. This module is engineered to provide continuous, simultaneous measurement of radial shaft vibration (XY) and probe gap voltage (GAP). By monitoring these parameters, the system offers critical protection for rotating machinery such as turbines, compressors, and pumps, facilitating the early detection of mechanical faults including shaft misalignment, rubs, and bearing degradation.

Features

• Dual-channel configuration for simultaneous XY vibration and GAP monitoring.
• Continuous comparison of input signals against user-defined Alert and Danger setpoints.
• Integrated relay outputs for automated alarm and shutdown sequences.
• Front-panel LED indicators for quick status verification of OK, Bypass, Alert, and Danger conditions.
• Compatible with standard proximity probe (Proximitor) sensor inputs.
• Proportional 4-20 mA outputs for integration with external DCS or PLC systems.

Applications

This monitor is widely utilized in industrial environments for the protection of critical rotating equipment, including:

• Steam and gas turbines
• Centrifugal compressors
• Large industrial pumps and motors
• Gearboxes and turbo-expanders

Technical Specifications

Installation Guidelines

• Ensure the 3300 rack is properly grounded according to site electrical safety standards to prevent noise interference.
• Handle the module using ESD-safe practices; avoid touching backplane connectors.
• Verify that the rack power is disconnected before inserting or removing the module to prevent electrical arcing or damage to the backplane pins.
• Ensure that shielded cables are used for proximity probe signals to minimize EMI/RFI impact.
• Confirm that the module is fully seated in the rack slot and that the front-panel locking mechanisms are engaged.

FAQ

What is the primary function of the 3300/16 monitor?

The 3300/16 is designed to monitor radial shaft vibration and probe gap voltage, providing essential data for machinery health and triggering alarms if pre-set vibration thresholds are exceeded.

Does this module include intrinsic safety barriers?

No, this specific model (3300/16-02-01-00-01-00-00) is configured with standard input barriers and does not include intrinsic safety barriers.

Can this module be used for both Alert and Danger alarms?

Yes, the module is equipped with relay outputs capable of managing both Alert and Danger alarm conditions based on the configured setpoints.
