Bently Nevada 330102-00-20-10-02-00 3300 XL 8 mm Proximity Probe

Product Overview

When monitoring critical rotating machinery, precise and reliable vibration measurement is essential. The Bently Nevada 330102-00-20-10-02-00 is a 3300 XL 8 mm Proximity Probe designed for non-contact displacement sensing. This probe uses eddy current technology to measure shaft vibration and position with high accuracy. Its robust construction, including a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, ensures durability in harsh industrial environments. The miniature coaxial ClickLoc connector simplifies installation and provides a secure connection.

Technical Specifications Breakdown

Key parameters for the 330102-00-20-10-02-00 are listed below for quick reference:

Industry Applications

This proximity probe is widely used in turbomachinery, compressors, pumps, and motors where shaft vibration and position monitoring are critical. Its 2 mm linear range and recommended -9 Vdc gap setting make it suitable for radial vibration measurements on journal bearings. By providing early detection of shaft displacement, the probe helps prevent catastrophic failures and reduces unplanned downtime.

Installation & Setup Guidance

For optimal performance, mount the probe with the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils from the target). Use the 3/8-24 UNF thread with a maximum thread engagement of 0.563 in. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. The maximum distance between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe is not exposed to temperatures below -34°C (-30°F) to avoid premature pressure seal failure.

Maintenance & Reliability

Regularly 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. Although not pressure tested before shipment, the seal integrity should be verified periodically in high-pressure applications. Operating temperature range is -52°C to +177°C (-62°F to +350°F) for standard probes. Humidity below 93% ensures less than 3% change in Average Scale Factor (ASF) per IEC 68-2-3.

Compatibility & Integration

This probe is part of the 3300 XL series and works with compatible Bently Nevada Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a reliable connection. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators for Class I, Zone 0 environments. For non-incendive circuits, follow drawing 140979 for Class I, Zone 2 applications.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), overall case length (2 in), and total length (1.0 m). The 330102-00-20-10-02-00 is available at AutoDCSTech.
