Bently Nevada 3300/16-15-01-03-00-00-02 Dual Vibration Monitor

Product Overview

The 3300/16-15-01-03-00-00-02 Dual Vibration Monitor from Bently Nevada is a 3300 Series protection module designed for continuous measurement of radial shaft vibration and average shaft position using proximity-based sensing technology. Installed in a 3300 rack system, this module provides two fully independent measurement channels for critical rotating machinery, supporting both machinery protection and condition monitoring strategies.

By accepting signals from matched proximity probes and Proximitor® signal conditioners, the monitor converts dynamic displacement data into scaled outputs and evaluates the results against configurable alarm thresholds in accordance with API 670 requirements.

Manufacturer and Identification

Brand: Bently Nevada 
Series: 3300 Machinery Monitoring System
Model / Order Number: 3300/16-15-01-03-00-00-02

Functional Description

The 3300/16-15-01-03-00-00-02 is engineered to supervise two radial measurement points, commonly arranged in an XY configuration on fluid-film bearings. Each channel independently processes vibration amplitude while also calculating average probe gap, enabling detection of both dynamic vibration behavior and static shaft position changes.

The module continuously compares real-time measurements to user-defined Alert and Danger setpoints, providing early warning and shutdown signals to protect machinery from mechanical damage caused by imbalance, misalignment, rubbing, or bearing degradation.

Technical Specifications

Comparison and Upgrade Notes

Compared with earlier dual radial vibration modules in the 3300 family, the 3300/16-15-01-03-00-00-02 expands protection capability by incorporating average shaft position (gap) monitoring. This allows both dynamic and static shaft conditions to be evaluated within a single module, reducing system complexity while improving diagnostic coverage.

FAQ

What sensors are required for this module?
The module requires matched proximity probes and compatible Proximitor® signal conditioners from the Bently Nevada 3300 Series.

Can each channel be configured independently?
Yes. Each channel supports independent alarm setpoints, signal processing, and output scaling.

Is this module suitable for protection-only systems?
Yes. It is commonly used in protection-focused installations and also supports condition monitoring through buffered outputs.

Does it require an external power supply?
No. Operating power is provided by the 3300 rack backplane.
