Technical Description
The 330104-10-20-10-02-CN is an 8 mm proximity probe from Bently Nevada's 3300 XL series, specifically designed for high-precision, non-contact measurement of shaft radial vibration, axial position, and rotor speed. Utilizing the eddy current principle, this probe converts the displacement between the probe tip and a metallic target (e.g., turbine rotor) into a highly linear, proportional voltage signal. The CN suffix indicates factory certification for use in China, meeting local regulatory requirements for hazardous area installations. Its stainless steel construction and PPS tip ensure reliability and longevity even in environments with high-pressure lubrication, synthetic fluids, and elevated thermal gradients typical of heavy-duty industrial machinery.

Operational Application
The 330104-10-20-10-02-CN proximity probe is used to monitor the mechanical integrity of critical rotating equipment such as steam/gas turbines, centrifugal compressors, and large-scale industrial pumps. By tracking shaft displacement, this probe enables real-time detection of rotor instability, misalignment, and bearing clearances. Integrating this probe into a comprehensive vibration monitoring system allows operators to shift from reactive to predictive maintenance strategies, identifying machine degradation before it leads to catastrophic failures.
Frequently Asked Questions
Why is the unthreaded length (100 mm) important for this configuration?
The 100 mm unthreaded length ensures the probe can be mounted at specific depths in equipment housings where the probe needs to pass through non-threaded sections before reaching threaded installation points.
Is the 330104-10-20-10-02-CN compatible with older 3300-series electronics?
No, the 3300 XL probe is designed specifically for use with 3300 XL Proximitor sensors. Mixing probes from different generations will result in system calibration errors and unreliable data.
Does the CN approval affect the probe's technical performance?
The CN approval pertains to regional regulatory compliance for use in hazardous areas within China. It does not affect the probe's electrical sensitivity, linearity, or physical dimensions compared to standard 330104 models.
