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

The Bently Nevada 330103-02-08-10-02-RU 3300 XL 8mm Proximity Probe is a precision sensor engineered for accurate measurement of shaft vibration and displacement in critical rotating machinery. Belonging to the 3300 XL series, this probe ensures reliable, repeatable measurements required for machinery protection, predictive maintenance, and operational efficiency.

This probe uses eddy current technology to convert the distance between the probe tip and the rotating shaft into an electrical signal with high fidelity. Its total length of 1 meter and weight of 0.323 kg make it suitable for medium-range installations while ensuring signal stability. The stainless steel housing provides durability against corrosion, vibration, and industrial stress. The RU designation indicates compliance with Russian industrial standards. The probe is fully compatible with Proximitor sensors and 3300 XL monitoring systems, providing high-accuracy data for early fault detection and machinery health monitoring.
