The Bently Nevada 330103-00-05-05-12-CN is a 3300 XL 8 mm eddy current proximity probe designed for precise measurement of shaft vibration and radial displacement in rotating machinery. It is widely applied in turbines, compressors, pumps, and other critical industrial systems where continuous condition monitoring is essential for reliability, safety, and predictive maintenance performance.
The “CN” suffix indicates a China-region certification / approval configuration (often including NEPSI and regional compliance packaging), while the electrical and mechanical performance remains aligned with the global 3300 XL proximity transducer system.
Technical Specifications
This model follows the standard 3300 XL ordering structure, where each segment defines probe geometry, cable length, and approval type.
