Bently Nevada 330704-000-050-10-02-CN Proximity Probe

Overview

The Bently Nevada 330704-000-050-10-02-CN belongs to the 3300 XL 11 mm proximity transducer family. This eddy-current sensor delivers non-contact shaft displacement and vibration measurements for critical rotating machinery. Consequently, engineers specify it across power generation, oil refining, and heavy manufacturing industries.

Technical Specifications

The probe features a 50 mm case length and a 1.0-meter integral cable. Its 1/2-20 UNF thread ensures compatibility with standard imperial mounting ports. Additionally, the 11 mm tip diameter provides a 4.0 mm linear range for large shaft movements.

Performance and System Integration

This probe pairs with 3300 XL 11 mm Proximitor sensors and matching extension cables. Therefore, it integrates seamlessly into existing machinery protection systems. The gold-plated ClickLoc connector with protector shields the interface from oil and moisture contamination.

Moreover, the non-contact eddy current technology maintains accuracy despite temperature fluctuations and industrial noise. The integrated connector protector reduces false alarms in harsh environments.

Applications and Reliability

Steam turbines, gas compressors, and large industrial pumps commonly rely on this probe. Maintenance teams deploy it for early detection of bearing wear and shaft instability. Each unit ships factory-sealed with a twelve-month warranty.
