Bently Nevada 3300/16-12-01-01-00-00 Dual Vibration Monitor Module

Product Overview

The Bently Nevada 3300/16-12-01-01-00-00 Dual Vibration Monitor is engineered for continuous protection of critical rotating machinery.
It measures two independent radial vibration channels while also calculating average shaft position for each channel.
Therefore, operators gain early visibility into mechanical instability, bearing wear, and shaft displacement trends.
This monitor operates as part of the proven Bently Nevada 3300 Series machinery protection system.
Moreover, it enhances legacy protection strategies by adding gap alarms beyond basic vibration monitoring.

Designed for fluid-film bearing machines, the 3300/16 supports long-term reliability in demanding industrial environments.
In addition, its modular rack-mounted design allows seamless integration into existing 3300 installations.

Key Features and Functional Benefits

The monitor processes two proximity probe inputs simultaneously for true dual-channel vibration analysis.
Moreover, each channel independently evaluates vibration amplitude and average shaft position in real time.
Gap alarm functionality provides earlier warning of bearing wear or shaft centerline movement.
Therefore, maintenance teams can act before damage escalates into forced outages.

High sensitivity ensures accurate detection of low-level vibration changes under stable operating conditions.
In addition, epoxy-sealed hermetic relays deliver dependable alarm performance in harsh industrial environments.
Compatibility with multiple Bently Nevada probe systems protects existing instrumentation investments.

Typical Applications and System Integration

This monitor is widely applied on gas, steam, and hydro turbines with fluid-film bearings.
For instance, it detects shaft vibration growth caused by imbalance, rubs, or oil film instability.
Compressors benefit from continuous gap monitoring during load changes and transient conditions.
Moreover, pumps and motors use the 3300/16 to identify misalignment and bearing degradation early.

Integration with a complete 3300 rack allows centralized power, alarms, and system expansion.
Therefore, facilities maintain consistent protection standards across multiple machine trains.

Reliability, Support, and Lifecycle Considerations

Bently Nevada designed the 3300/16 for long service life in continuous duty environments.
Moreover, its solid-state electronics minimize drift and calibration requirements over time.
Spare parts availability and long-term documentation support legacy system maintenance strategies.
Therefore, operators confidently sustain older machinery without sacrificing protection integrity.
