Bently Nevada 330703-000-090-10-02-CN 3300 XL Proximity Probe

Overview

The Bently Nevada 330703-000-090-10-02-CN operates 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 90 mm overall case length and a fully threaded M14 × 1.5 metric body. Its 1.0-meter integrated cable terminates with a miniature coaxial ClickLoc connector. 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 3300 and 3500 monitoring systems. The gold-plated ClickLoc connector locks firmly to prevent signal loss from machine vibration.

Moreover, the patented TipLoc molding method creates a robust bond between the probe tip and body. The 75-ohm triaxial FEP cable with 99.9% braided copper shielding resists electrical interference in demanding industrial settings.

Applications and Reliability

Steam turbines, gas compressors, and large industrial pumps commonly rely on this probe. Maintenance teams deploy it for axial thrust position, radial vibration, and Keyphasor phase reference measurements. Each unit ships factory-sealed with a twelve-month warranty.
