The Bently Nevada 330103-02-08-10-02-05-00 3300 XL 8mm Proximity Probe is a high-precision sensor designed for measuring shaft vibration and displacement in critical rotating machinery. As part of the 3300 XL series, this probe ensures reliable and accurate measurements, which are essential for machinery protection, predictive maintenance, and operational safety.

The probe utilizes eddy current technology to convert the gap between the probe tip and the rotating shaft into an accurate electrical signal. With a total length of 1 meter and a weight of 0.323 kg, it is ideal for medium-range installations while maintaining stable signal transmission. The stainless steel housing provides robustness against corrosion, vibration, and industrial stress, making it suitable for harsh environments. This model is fully compatible with Proximitor sensors and 3300 XL monitoring systems, providing high-fidelity data for operational monitoring.
