Application Scenarios
In steam turbines, compressors, and large motors, the 330709-000-080-50-11-05 provides accurate shaft vibration data. Its M16x1.5 thread and 24 mm engagement length allow secure mounting in standard probe holders. The fluid-resistant cable and connector protector minimize signal degradation in wet or corrosive environments. This probe is also suitable for axial position monitoring in gearboxes and pumps.
Installation & Setup Guide
Ensure probe tip clearance meets recommended minimum shaft diameter of 152 mm for flat surfaces. Use recommended torque values: 21.1 N·m for case mounting and finger tight for the connector. Avoid bending the cable beyond a 25.4 mm radius. For optimal performance, maintain operational temperature within -52°C to +177°C and avoid exposure below -34°C to prevent pressure seal failure. The five-meter probe must be used with a compatible five-meter Proximitor sensor.
Maintenance & Reliability
Inspect the connector and cable regularly for wear or damage. The 304 stainless steel case and PPS tip resist corrosion in demanding environments. The 330709-000-080-50-11-05 comes with multiple agency approvals, ensuring compliance with international standards. For long-term reliability, follow the temperature schedules for EPL Ga/Gc and Dc classifications to avoid thermal stress.
Selection Guide & Purchasing Advice
When ordering, verify that the probe length (5.0 meters) matches your system requirements. The 330709-000-080-50-11-05 includes a miniature coaxial ClickLoc connector with protector and FluidLoc cable. For consistent performance, pair it with a Bently Nevada Proximitor sensor of the same length. UBEST Automation (ubest101) offers this genuine Bently Nevada probe with full traceability.
