The Bently Nevada 330104-15-25-10-01-CN proximity probe is a high-precision eddy-current sensor engineered for continuous, non-contact measurement of shaft vibration, radial displacement, and rotor position in rotating machinery.

Based on the reliable 3300 XL 8 mm proximity transducer system, this probe is designed for demanding industrial environments where long-term measurement stability, high signal accuracy, and strong immunity to electromagnetic interference are essential for effective machinery protection and condition monitoring.

The “15-25-10” configuration typically represents an extended and reinforced probe assembly intended for large rotating equipment with deeper installation requirements and complex mounting geometries. The “-01-CN” suffix generally indicates a standard connector configuration combined with a China-region variant used for localized deployment, compliance, or supply-chain standardization.
