Bently Nevada 330104-04-10-10-02-CN 3300 XL 8 mm Proximity Probe

Product Introduction

When machinery vibration threatens uptime, the Bently Nevada 330104-04-10-10-02-CN provides precise, non-contact displacement measurement. This 3300 XL 8 mm proximity probe is designed for critical rotating equipment monitoring. It features an M10 x 1 thread with armor for robust installation. The probe uses a miniature coaxial ClickLoc connector and standard cable, ensuring reliable signal transmission in harsh industrial environments. Manufactured in the U.S.A., this probe is a trusted component for predictive maintenance programs.

Technical Specifications Breakdown

The 330104-04-10-10-02-CN offers key parameters that define its performance. The unthreaded length option is 04 mm, providing precise mounting flexibility. The overall case length option is 10 mm, and the total length option is 1.0 meter (3.3 feet), allowing for standard installation distances. The probe tip is made of polyphenylene sulfide (PPS), offering excellent chemical resistance and durability. The probe case is constructed from AISI 303 or 304 stainless steel (SST), ensuring corrosion resistance in demanding environments. The nominal probe DC resistance from center conductor to outer conductor is 7.59 ± 0.50 ohms at 1.0 meter length, which is critical for system calibration and accuracy.

Industry Applications

This proximity probe excels in vibration monitoring for turbines, compressors, pumps, and motors. In a typical steam turbine application, the 330104-04-10-10-02-CN mounts near the bearing housing to measure shaft displacement. Its 8 mm sensing face provides a linear output over a wide range, enabling early detection of imbalance or misalignment. The armored cable resists abrasion in high-vibration zones, reducing maintenance interventions. For centrifugal compressors, the probe's PPS tip withstands oil mist and contaminants, ensuring long-term reliability.

Installation & Setup Guidance

Proper installation of the 330104-04-10-10-02-CN is essential for accurate readings. Mount the probe using the M10 x 1 thread into a compatible mounting block or bracket. Ensure the probe tip is clean and free of debris before insertion. Gap the probe at 1.27 mm (50 mils) to an AISI 4140 steel target for optimal performance. Use the miniature coaxial ClickLoc connector to attach the extension cable, ensuring a secure, twist-lock connection. Avoid sharp bends in the standard cable to prevent signal degradation. Calibrate the system with a 3300 XL Proximitor Sensor and extension cable for best results.

Maintenance & Reliability

The 330104-04-10-10-02-CN is designed for minimal maintenance. The stainless steel case and PPS tip resist corrosion and wear. Periodically inspect the probe cable for cuts or abrasions, especially near the connector. Check the mounting thread for damage during routine outages. The probe's sealing material consists of a Viton O-ring, which maintains differential pressure between the tip and case. Replace the O-ring if leakage is suspected. Regular verification of the probe's DC resistance (7.59 ± 0.50 ohms) helps confirm cable integrity.

Compatibility & Integration

This probe is part of the 3300 XL system and works exclusively with 3300-series 5 mm or 3300 XL 8 mm proximity probes and extension cables. It requires a compatible 3300 XL Proximitor Sensor for signal conditioning. The system operates with a -17.5 Vdc to -26 Vdc power supply when installed with non-incendive circuits, and -23 Vdc to -26 Vdc with barriers. The output resistance is 50 ohms. For best accuracy, use only 3300 XL 8 mm components together. The probe is not compatible with other brands or series without proper adapter kits.

Selection Guide & Purchasing Advice

When ordering the 330104-04-10-10-02-CN, verify the total length (1.0 meter) and connector type (miniature coaxial ClickLoc) match your system requirements. The agency approval option is CN (Country Specific Approval). Ensure your Proximitor Sensor and extension cable are also 3300 XL series.
