Bently Nevada 330703-000-100-10-02-CN Proximity Probe

Overview

The Bently Nevada 330703-000-100-10-02-CN serves as a core sensing element within the 3300 XL 11 mm Proximity Transducer System. This eddy-current probe delivers non-contact displacement and vibration measurements for critical rotating machinery. Consequently, engineers deploy it across steam turbines, centrifugal compressors, and other heavy industrial equipment.

Technical Specifications

The probe features a 100 mm case length and a 1.0-meter cable. Its M14 × 1.5 metric thread ensures secure mounting in standard ports. Additionally, the 11 mm tip diameter provides an extended 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 3300 and 3500 monitoring 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 100 mm case length allows installation through thick machine housings and insulation layers.

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.
