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

Product Description

The 3300/16-XX-01-03-00-00-02 Dual Vibration Monitor is a protection and condition monitoring module designed for the Bently Nevada 3300 Machinery Protection System. It is engineered to continuously supervise two independent proximity probe channels, providing precise measurement of radial shaft vibration along with average shaft position (gap).

Installed within a 3300/05 rack, this module processes signals from proximity probes via Proximitor® sensors and evaluates them against configurable alarm thresholds. Its design supports long-term, stable monitoring of critical rotating equipment and aligns with API 670 requirements for machinery protection systems.

The “XX” identifier in the model number denotes mechanical configuration or certification variations, allowing the monitor to be matched to specific rack layouts or regional approval requirements.

Key Functional Capabilities

The 3300/16-XX-01-03-00-00-02 supports dual-channel monitoring, enabling simultaneous supervision of X-Y vibration or vibration combined with shaft gap reference. Each channel operates independently, ensuring reliable fault detection even in complex bearing arrangements.

Integrated alert and danger alarms provide early warning and shutdown capability when vibration or position limits are exceeded. Scaled analog outputs allow the module to interface with external control or data acquisition systems for trending and diagnostics.

Technical Specifications

• Monitoring Channels: Two fully independent channels

• Sensor Compatibility: Proximity probes with 3300 Proximitor® signal conditioners

• Measured Quantities:

• Radial shaft vibration (dynamic AC component)

• Average shaft position / gap (DC component)

• Frequency Response: Suitable for high-frequency machinery vibration measurement (typical 3300 system bandwidth)

• Power Requirement: Supplied directly from the 3300 rack backplane

• Alarm Configuration: User-adjustable Alert and Danger setpoints per channel

• Outputs: Buffered voltage outputs for vibration and position signals

• Installation: Slides into standard slots of the 3300/05 rack

• Standards Compliance: Designed to meet API 670 machinery protection guidelines

• Service Life: Intended for continuous 24/7 industrial operation

System Integration

This monitor operates as part of a complete 3300 protection rack, sharing power and signal routing through the rack backplane. It is typically paired with 3300-series proximity probes, extension cables, and Proximitor® modules, forming a stable and repeatable measurement chain from sensor to alarm output.

Typical Applications

• Steam and gas turbines requiring continuous radial vibration protection

• Centrifugal and axial compressors with proximity-based monitoring schemes

• High-speed pumps and motors where shaft movement and vibration are critical

• API 670-compliant protection systems in oil & gas, petrochemical, and power generation facilities

Model Comparison Note

Compared with earlier dual vibration modules in the 3300 family, the 3300/16-XX-01-03-00-00-02 extends protection functionality by incorporating average shaft position (gap) monitoring in addition to standard radial vibration, reducing the need for separate gap-only modules in certain configurations.

FAQ

Q: Can this module operate with a single probe installed?
A: Yes. Each channel is independent, allowing one or two probes to be configured depending on the application.

Q: Is this module compatible with non-3300 racks?
A: No. It is designed exclusively for installation in Bently Nevada 3300/05 racks.

Q: Does the module provide shutdown capability?
A: Yes. Alarm outputs can be wired to trip circuits or control systems to initiate protective shutdowns when danger limits are exceeded.
