One standout spec is the patented TipLoc and CableLoc designs, which provide 330 N (75 lbf) pull strength for secure cable attachment. This reduces downtime caused by cable failures in high-vibration settings.

Real-World Applications for the 330101-00-11-10-02-CN

This probe excels in rotating machinery monitoring, such as turbines, compressors, and pumps. Its 8 mm diameter offers a thicker PPS encapsulation, making it more rugged than smaller probes. In oil and gas facilities, the optional FluidLoc cable prevents liquid leaks through the cable interior. The linear range of 2 mm (80 mils) ensures accurate vibration readings from 0.25 mm to 2.3 mm, ideal for early fault detection.

Installation Guide for the 3300 XL Probe

Mount the probe using the 3/8-24 UNF thread into a suitable mounting block. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. The maximum cable length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). Set the recommended gap for radial vibration to -9 Vdc, approximately 1.27 mm (50 mils). Ensure the probe tip is clean and free from debris before installation.

Maintenance & Reliability Tips

Regularly inspect the probe cable and connector for wear, especially in high-temperature environments. The probe operates reliably from -52°C to +177°C, but exposure below -34°C may cause premature pressure seal failure. The Viton O-ring seals differential pressure, but probes are not pressure tested before shipment. For extended temperature ranges, the probe tip can withstand up to +218°C. Periodic verification of the Incremental Scale Factor ensures measurement accuracy.

Compatibility & Integration

The 330101-00-11-10-02-CN integrates seamlessly with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. The ClickLoc connector simplifies cable attachment. Use with standard 5 or 1 meter systems for optimal performance. For extended temperature range systems, the ISF remains within ±6.5%.
