Industry Applications
The Bently Nevada 330709-000-050-10-02-05 3300 XL 11 mm Proximity Probes are ideal for monitoring shaft vibration and position in turbines, compressors, pumps, and large electric motors. In refineries, chemical plants, and power generation facilities, these probes help prevent catastrophic failures by delivering real-time data to vibration monitoring systems. Upgrade your legacy Bently Nevada probes with this modern replacement that offers improved reliability and the same form factor.
Installation Guidance
Proper mounting ensures accurate readings. Use the M16x1.5 thread and tighten the probe case to 21.1 N·m (187 in·lb). Do not exceed the 24 mm thread engagement. Connect the mini coaxial ClickLoc connector hand-tight, then torque to 0.565 N·m maximum. Maintain a minimum bend radius of 25.4 mm for the cable to avoid damage. For cross-talk prevention, ensure the target flat surface diameter is at least 30.5 mm and shaft diameter at least 152 mm.
Maintenance & Reliability
These probes are built for long service life. The PPS tip and 304 SST case withstand harsh conditions. However, avoid prolonged exposure below -34°C (-30°F) as it may cause premature seal failure. Periodically inspect the cable for kinks or cuts and verify connector integrity. The 330709-000-050-10-02-05 model's standard cable and ClickLoc connector simplify replacement. Routine resistance checks (5.9 ± 0.5 Ω at 1.0 m) confirm proper coil condition.
Selection Guide
When ordering a replacement or new installation, verify the total probe length (here: 1.0 metre, option 10) and connector/cable type (option 02: miniature coaxial ClickLoc, standard cable). For different lengths or armored versions, consult the full 330709 series options.
