The Bently Nevada 330104-10-20-10-02-CN proximity probe is a high-precision eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, radial displacement, and rotor position in rotating machinery.
As part of the established 3300 XL 8 mm proximity transducer system, this probe is engineered for industrial environments where long-term signal stability, measurement accuracy, and resistance to electromagnetic interference are essential. It is widely used in condition monitoring and machinery protection systems across power generation, oil and gas, petrochemical, and heavy industrial applications.
The “10-20-10” configuration typically represents an extended probe assembly intended for larger machinery layouts requiring flexible installation routing and stable measurement performance over longer distances. The “-02-CN” suffix generally indicates a standardized connector configuration combined with a China-region variant, often used for localized compliance, packaging, or supply chain requirements.
