Product Description

The Bently Nevada 3300/16-02-01-01-00-00-02 is a dual-channel XY/GAP vibration monitor from the legacy 3300 series, engineered to deliver precise, real-time monitoring of radial vibration and shaft position. Designed for turbines, compressors, motors, and pumps, this module interfaces with Proximitor® sensors to provide critical feedback for machinery protection and performance analysis.

This monitor continuously measures two independent vibration channels and calculates the average shaft position (gap), allowing engineers to detect potential faults early and maintain machinery reliability.

Key Features

• Dual Independent Channels: Simultaneously monitors two vibration signals for amplitude and DC gap voltage.

• Proximity Sensor Compatible: Supports 3300 XL 8 mm, 3300 8 mm, or 7200 5/8 mm Proximitor® transducers at 200 mV/mil.

• Wide Frequency Response: Effective monitoring from 0 Hz to 100 kHz, suitable for high-speed rotating equipment.

• High Accuracy: Typical signal conditioning accuracy ±0.33% of full-scale, ensuring reliable measurements.

• Gap and Orbit Tracking: Provides real-time indication of shaft position to detect bearing wear or misalignment.

• Trip Multiply Function: Allows temporary alarm threshold adjustments (3X in this configuration) to avoid nuisance trips during startup.

• Front-Panel Indicators: LED status for OK, Alert/Danger, and Bypass, providing instant operational feedback.

• Buffered Outputs: Coaxial connectors for external vibration analyzers without affecting monitoring.

• Rugged Design: Operating temperature from -40°C to +70°C and 0–95% non-condensing humidity.

Technical Specifications

Application Scenarios

The 3300/16 dual vibration monitor is suitable for continuous monitoring of critical rotating machinery such as turbines, compressors, motors, and pumps. Ideal for protection against imbalance, misalignment, or bearing wear, it integrates seamlessly with existing 3300 series racks. The device is particularly effective in high-speed or harsh industrial environments requiring precise shaft orbit tracking and vibration feedback.

FAQ

Q: What sensors are compatible with this monitor?
A: Compatible with 3300 8 mm, 3300 XL 8 mm, and 7200 5/8 mm Proximitor® sensors.

Q: Does this module support hot-swapping?
A: No, it requires rack power-down for replacement in legacy 3300 series systems.

Q: What is the purpose of the Trip Multiply function?
A: Allows temporary alarm threshold adjustment during high-vibration events, such as machine startup, to prevent nuisance trips.

Q: Can it be replaced with a 3500 series module?
A: The 3500 series is the modern replacement, but ensure backplane compatibility when upgrading from a 3300 series monitor.
