The Bently Nevada 330103-02-07-50-02-00 3300 XL 8mm Proximity Probe is a precision-engineered sensor designed for accurate measurement of shaft vibration and displacement in critical rotating machinery. As a member of the 3300 XL series, this probe provides high reliability, consistent measurement performance, and robust operation in demanding industrial environments.

This probe employs eddy current technology to detect the gap between the probe tip and the rotating shaft. Its 5-meter total length and 1.615 kg weight make it suitable for installations where long-distance cable routing is required without compromising signal integrity. The stainless steel housing ensures durability against corrosion, vibration, and mechanical stress. This model is optimized for integration with Proximitor sensors and 3300 XL monitoring systems, providing stable, high-fidelity data for machinery protection and predictive maintenance programs.
