Industry Applications
The Bently Nevada 330708-00-24-50-02-05 excels in critical rotating machinery monitoring, including turbines, compressors, and pumps in oil & gas, power generation, and chemical processing. Its wide temperature tolerance allows deployment in outdoor or high-heat zones, while the pressure-sealed design prevents contamination ingress. The miniature ClickLoc connector simplifies installation in tight spaces.
Installation & Setup Guidance
Install the probe with a thread engagement of no more than 0.938 inches for 5/8-18 threads. Tighten the probe case to 15.2 N·m (133 in·lb) using a torque wrench. For the connector, use only finger-tight torque (max 0.565 N·m). Avoid bending the cable beyond the 25.4 mm radius to prevent damage. Ensure the target surface is clean and non-magnetic for accurate eddy-current sensing.
Maintenance & Reliability
The 3300 XL probe is designed for long-term reliability. Inspect the cable and connector periodically for wear, especially in high-vibration environments. The Viton O-ring pressure seal minimizes leakage, but avoid exposing the probe to temperatures below -34°C (-30°F) to prevent seal failure. If pressure testing is required, contact UBEST Automation for custom solutions.
Selection Guide
When choosing the Bently Nevada 330708-00-24-50-02-05, verify compatibility with your Proximitor sensor (5-meter only). This probe suits applications needing a 5/8-18 thread and no armor. For different cable lengths or armor options, consider other 3300 XL variants.
