When selecting a proximity probe for critical rotating machinery, the Bently Nevada 330101-00-11-20-02-05 stands out due to its robust design and proven performance. This 3300 XL 8 mm probe, with a 3/8-24 UNF thread and no armor, offers a patented TipLoc molding method for a stronger bond between the probe tip and body. The CableLoc design provides 330 N (75 lbf) pull strength, ensuring reliable operation in demanding environments.

Industry Applications
Its 2 mm linear range and high sensitivity (7.87 V/mm) allow precise measurement of shaft displacement. The CSA, ATEX, and IECEx approvals make it suitable for hazardous areas, reducing the risk of failure in explosive environments.
Installation & Setup Guidance
For optimal performance, set the recommended gap to -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration applications. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. The maximum field wiring length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and the mounting surface is free of debris.
Maintenance & Reliability
The 330101-00-11-20-02-05 probe is designed for long-term reliability. The PPS tip and stainless steel case resist corrosion and physical abuse. Inspect the cable and connector periodically for wear. The probe can operate in temperatures from -52°C to +177°C, but avoid exposing it to below -34°C (-30°F) to prevent premature failure of the pressure seal.
Selection Guide & Purchasing Advice
When ordering the 330101-00-11-20-02-05, verify the total length (2.0 meters) and connector type (miniature coaxial ClickLoc) match your system requirements.
