The Bently Nevada 330103-00-04-05-02-RU is a 3300 XL 8 mm eddy current proximity probe designed for high-precision shaft vibration and position measurement in rotating machinery. It is commonly deployed in turbines, compressors, pumps, and other critical industrial assets where continuous monitoring is required for machinery protection and predictive maintenance.

The “RU” suffix generally indicates a region-specific approval/configuration (often related to EAC/GOST compliance for CIS/Russian-market deployments) while maintaining full compatibility with the standard 3300 XL system architecture.
