Industry Applications
The Bently Nevada 330707-00-62-50-11-00 3300 XL 11 mm Proximity Probes is widely used in turbomachinery, compressors, and large pumps for real-time shaft vibration and position monitoring. Its PPS tip and stainless steel case withstand corrosive atmospheres and high temperatures found in oil & gas refineries and power generation. The 5-meter cable and ClickLoc connector simplify installation in tight cable trays.
Installation & Setup Guidance
Mount the Bently Nevada 330707-00-62-50-11-00 probe in a 1/2-20 UNF tapped hole. Ensure thread engagement does not exceed 0.750 in to avoid binding. Apply the recommended 15.2 N•m torque to the case; never exceed 45.2 N•m. For the ClickLoc connector, use only finger-tight torque (max 0.565 N•m) to prevent connector damage. Maintain a minimum bend radius of 25.4 mm for the cable to avoid internal strain. The probe must be paired with a compatible 5-meter Proximitor sensor only.
Maintenance & Reliability
Routine inspection of the probe cable and connector for cuts or corrosion extends service life. Avoid exposing the probe to temperatures below -34°C (-30°F), as premature pressure seal failure may occur. The Viton O-ring seals the probe tip from the case; verify seal integrity during each maintenance cycle. The armored FluidLoc cable reduces wear from vibration, aligning with a failure-prevention strategy.
Selection Guide & Purchasing Advice
Before ordering, confirm that your system requires a 5-meter total probe length and a miniature ClickLoc connector. The 330707-00-62-50-11-00 is designed for use with the 5-meter Proximitor sensor only; do not mix cable lengths.
