The Bently Nevada 330104-00-05-90-02 Proximity Probe Module is a high-performance non-contact eddy-current sensor designed for accurate shaft vibration, position, and displacement measurement in mission-critical rotating machinery. As a member of the renowned 3300 XL 8 mm Proximity Transducer System, this probe delivers outstanding reliability, excellent signal stability, and long-term measurement accuracy for industrial asset protection programs.
This configuration features a 50 mm case length (Option 05), a 9.0-meter total system length (Option 90), and a Miniature Coaxial ClickLoc connector with standard cable (Option 02). The extended cable length makes it ideal for large-scale machinery installations where monitoring cabinets are located far from the machine train. The model is commonly deployed in turbines, compressors, generators, pumps, and other high-value rotating assets where continuous condition monitoring is essential.
Built to support predictive maintenance strategies, the probe provides accurate machinery condition data that helps maintenance teams identify imbalance, misalignment, bearing wear, shaft rub, and other developing mechanical issues before they result in costly downtime.
