Installation & Setup Guidance
Install the Bently Nevada 330709-000-030-50-01-00 3300 XL 11 mm Proximity Probe using a torque wrench set to 21.1 N•m for the M16x1.5 thread. Apply the connector only finger tight; do not exceed 0.565 N•m. Maintain a minimum bend radius of 25.4 mm on the cable to prevent internal damage. Ensure the threaded hole engagement does not exceed 24 mm to avoid binding.
Maintenance & Reliability
Regularly inspect the probe cable and connector for cuts or kinks. Avoid exposing the probe to temperatures below -34°C (30°F) as this may cause premature seal failure. The probe operates reliably across a wide temperature range of -52°C to +177°C. For hazardous locations, follow the temperature classification schedules provided in the datasheet.
Troubleshooting & Common Issues
Cross-talk problems: Ensure the target and shaft diameters meet the recommended minimums (30.5 mm target and 152 mm shaft). Incorrect readings: Verify that the probe is used only with a 5-meter Proximitor sensor – the 330709-000-030-50-01-00 is designed specifically for this pair. Over-torquing: Exceeding the recommended 21.1 N•m can strip the threads; always use a calibrated torque wrench.
Selection Guide & Purchasing Advice
Before purchasing the Bently Nevada 330709-000-030-50-01-00 3300 XL 11 mm Proximity Probe, confirm that your existing Proximitor sensor is the 5-meter model. This probe includes a miniature coaxial ClickLoc connector with connector protector and a standard cable.
