Installation & Setup Guidance
Proper installation of the Bently Nevada 330708-00-24-90-12-00 3300 XL 11 mm Proximity Probe ensures optimal performance. Engage the 5/8-18 thread to a maximum depth of 0.938 inches. Apply the recommended probe case torque of 15.2 N·m (133 in·lb) to avoid damaging the probe. For the coaxial ClickLoc connector, tighten finger tight only; do not exceed 0.565 N·m (5 in·lb). Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable to prevent internal damage. Note that the probe is not pressure tested before shipment; contact our custom design department if pressure sealing verification is required.
Maintenance & Reliability
The Bently Nevada 330708-00-24-90-12-00 3300 XL 11 mm Proximity Probe operates reliably in temperatures from -51°C to +177°C. However, exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Store the probe within the specified range of -52°C to +177°C. The Viton O-ring provides a differential pressure seal between the tip and case. Regular inspection of the cable and connector for wear is recommended to maintain measurement integrity. Choose this probe as an upgrade from older models for extended service life and consistent accuracy.
Selection Guide & Purchasing Advice
When selecting the Bently Nevada 330708-00-24-90-12-00 3300 XL 11 mm Proximity Probe, verify that the required total length matches your application—this unit comes with a 9.0-meter cable. The 5/8-18 UNF thread is standard for many mounting configurations. Ensure your monitoring system accepts the miniature coaxial ClickLoc connector.
