Industry Applications
Its 2 mm linear range and recommended -9 Vdc gap setting provide optimal sensitivity for radial vibration measurements. The PPS tip and stainless steel case withstand harsh conditions, while CSA, ATEX, and IECEx approvals allow installation in hazardous areas. Engineers rely on this model for accurate shaft displacement data that drives condition-based maintenance programs, reducing unplanned downtime and repair costs.
Installation & Setup Guidance
Proper installation is critical for accurate readings. Use the 3/8-24 UNF thread and observe the maximum thread engagement of 0.563 in. Field wiring should be 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable, tinned ends. Maximum cable length between the Proximitor sensor and monitor is 305 meters (1,000 feet). For radial vibration, set the gap to approximately -9 Vdc (1.27 mm or 50 mils). Ensure the probe tip is clean and the target surface is smooth and electrically conductive.
Maintenance & Reliability
The probe is designed for long-term reliability in industrial environments. The Viton® O-ring provides a pressure seal, but probes are not pressure tested before shipment. Inspect the probe and cable periodically for damage, especially in high-temperature or high-humidity conditions. The probe relative humidity test shows less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.
Solving Vibration Monitoring Challenges in Rotating Machinery
In critical rotating equipment such as turbines, compressors, and pumps, precise shaft vibration measurement is essential to prevent catastrophic failures. The Bently Nevada 330102-00-20-10-11-05 3300 XL 8 mm Proximity Probe delivers reliable, non-contact displacement sensing even in the most demanding conditions.
Compatibility & Integration
This probe is designed for use with Bently Nevada 3300 XL Proximitor sensors. The 1.0-meter probe length is intended for use with the 5-meter Proximitor sensor only. The miniature coaxial ClickLoc connector with connector protector ensures secure, reliable connections in high-vibration environments. The FluidLoc cable provides additional protection against fluid ingress.
Selection Guide & Purchasing Advice
When selecting a proximity probe, consider the total cable length, thread type, and required agency approvals. The 330102-00-20-10-11-05 offers a 1.0-meter length with CSA, ATEX, and IECEx certifications, making it suitable for global hazardous area installations.
