Bently Nevada 330103-02-08-10-02-05-RU 3300 XL 8mm Proximity Probes

The Bently Nevada 330103-02-08-10-02-05-RU 3300 XL 8mm Proximity Probe is a precision-engineered sensor specifically designed for monitoring shaft vibration and displacement in critical rotating machinery. As part of the 3300 XL series, it provides high-fidelity, repeatable measurements essential for machinery protection, predictive maintenance, and operational efficiency.

This probe employs eddy current technology, which converts the gap between the probe tip and the rotating shaft into a reliable electrical signal. Its total length of 1 meter and weight of 0.323 kg make it suitable for medium-distance installations where signal stability and mechanical flexibility are required. The stainless steel housing ensures robust performance under vibration, shock, and corrosion. The RU designation indicates compliance with Russian industrial standards, making it suitable for both local and international applications. Fully compatible with Bently Nevada Proximitor sensors and 3300 XL monitoring systems, it delivers consistent, high-accuracy data for early fault detection and machinery health monitoring.
