Robust Vibration Sensing for Critical Machinery
When protecting turbomachinery, compressors, and large pumps, the Bently Nevada 330101-00-20-20-12-05 3300 XL 8 mm probe delivers the ruggedness and precision you need. This non-contact eddy current probe is designed for reliable shaft vibration and position measurement in harsh industrial environments. Its 3/8-24 UNF thread and 2.0 m miniature coaxial ClickLoc connector with FluidLoc cable simplify installation while preventing oil leakage.

Industry Applications
The 8 mm diameter provides a thicker PPS tip encapsulation for enhanced durability against physical abuse compared to smaller probes.
Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread into a suitable mounting boss. Set the initial gap to achieve approximately -9 Vdc output, corresponding to about 1.27 mm (50 mils) from the target. Use 3-conductor shielded triad cable for field wiring up to 305 meters (1,000 feet) to the Proximitor. Ensure the probe tip is clean and free of debris before final tightening.
Maintenance & Reliability
The stainless steel case and PPS tip resist corrosion and wear. Inspect the probe cable and connector periodically for damage, especially in high-vibration areas. The patented CableLoc design provides 330 N (75 lbf) pull strength to secure the cable. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent pressure seal failure.
Compatibility & Integration
This probe is part of the 3300 XL system and works with Bently Nevada Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure, quick connection. The CSA, ATEX, and IECEx approvals allow use in hazardous area installations.
