Product Description

Overview

The Bently Nevada 330180-91-05 is a high-precision 3300 XL 8mm Proximitor Sensor designed to measure shaft displacement and vibration in fluid-film bearing machines such as turbines, compressors, and electric motors. This non-contact sensor converts shaft motion into a reliable analog signal for condition monitoring and predictive maintenance applications. The -05 suffix denotes multi-agency hazardous area approvals, including CSA/NRTL/C for Class I, Division 2 installations.

Technical Specifications

Functional Highlights

• Hazardous Area Certification: Compliant with CSA/NRTL/C Class I, Division 2 requirements for safe industrial deployment.

• Full Interchangeability: Compatible with all 3300 XL 8mm probes and extension cables, no field recalibration needed.

• Legacy Compatibility: Backward-compatible with 3300 5mm and 8mm standard series sensors.

• High-Temperature Operation: Maintains measurement accuracy under extreme thermal conditions.

• Robust Connection: Gold-plated ClickLoc connectors provide corrosion resistance and secure signal transmission.

• Compact DIN Mounting: Allows easy installation in crowded control panels and fiberglass enclosures.

• API 670 Compliance: Meets standards for linearity, frequency response, and mechanical configuration.

Applications

• Radial vibration measurement for fluid-film bearings

• Axial shaft position and thrust monitoring

• Phase reference (Keyphasor) for vibration phase and speed analysis

• Shaft eccentricity detection in turbines and compressors

Usage Notes

Ensure the total electrical length of the system matches 9.0 meters. Using shorter cables with a 9.0m Proximitor will result in significant measurement errors and non-linear outputs.
