Bently Nevada 330102-24-72-10-02-CN 3300 XL 8 mm Proximity Probe

Precision Vibration Monitoring with the Bently Nevada 330102-24-72-10-02-CN

For critical rotating machinery, accurate vibration measurement is non-negotiable. The Bently Nevada 330102-24-72-10-02-CN is a 3300 XL 8 mm proximity probe engineered for reliable, real-time shaft displacement monitoring. This probe is part of the trusted 3300 XL series, designed to deliver consistent performance in demanding industrial environments.

Technical Specifications Breakdown

Key parameters for the 330102-24-72-10-02-CN are listed below for quick reference:

Industry Applications

Its 2 mm linear range and -9 Vdc recommended gap setting provide a solid baseline for radial vibration measurements. The PPS tip and stainless steel case withstand harsh conditions, making it suitable for refineries, power plants, and chemical processing facilities.

Installation & Setup Guidance

When installing the 330102-24-72-10-02-CN, ensure the probe tip is clean and the target surface is smooth. The maximum thread engagement for the 3/8-24 thread is 0.563 inches. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable. The maximum field wiring length between the probe and monitor is 305 meters (1,000 feet). Always verify the gap voltage setting to -9 Vdc for radial vibration applications.

Maintenance & Reliability

Periodically inspect the probe cable and connector for damage. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe's relative humidity performance shows less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3.

Compatibility & Integration

The 330102-24-72-10-02-CN is compatible with Bently Nevada 3300 XL Proximitor sensors. For 1.0 meter probes, use the standard Proximitor sensor. Note that 3-meter probes are only for 330101 models with 9-meter sensors, and 5-meter probes require 5-meter Proximitor sensors. The probe can be installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators for hazardous area use.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the total length, thread size, and connector type. The 330102-24-72-10-02-CN offers a 1.0 meter cable with a miniature coaxial ClickLoc connector.
