Compact 80 mm Metric Probe with CN Approval for Precision Machinery Monitoring
The Bently Nevada 330103-00-08-05-01-CN 3300 XL 8 mm Proximity Probe is a high-accuracy non-contact eddy current sensor designed to monitor shaft vibration, radial displacement, axial position, and rotor dynamics in critical rotating equipment. As a member of the renowned 3300 XL 8 mm Proximity Transducer System, this probe delivers exceptional measurement stability, long service life, and dependable performance in demanding industrial environments. Its compact design and robust construction make it an excellent choice for predictive maintenance and machinery protection systems.
This configuration features an M10 × 1 metric thread, 0 mm unthreaded length, 80 mm overall case length, 0.5-meter integral cable, a Miniature Coaxial ClickLoc™ connector with connector protector, and the CN country-specific approval option, making it suitable for installations requiring Chinese hazardous-area certifications.
Engineered for Stable and Accurate Shaft Measurement
The 330103-00-08-05-01-CN measures the distance between the probe tip and a conductive shaft using advanced eddy current technology. The resulting voltage output is directly proportional to shaft movement, enabling continuous monitoring of vibration, shaft position, eccentricity, and rotational speed reference applications.
When combined with a compatible 3300 XL Extension Cable and 3300 XL Proximitor® Sensor, the probe forms a complete transducer system capable of delivering reliable condition monitoring data for turbines, compressors, pumps, motors, and generators. The integrated connector protector also provides additional mechanical protection during installation and maintenance.
