Product Overview: Bently Nevada 330707-00-62-50-11-05 3300 XL 11 mm Proximity Probe
The Bently Nevada 330707-00-62-50-11-05 is a precision 3300 XL 11 mm proximity probe designed for critical rotating machinery monitoring. This probe offers robust construction with a 1/2-20 UNF thread, armor protection, and a 5.0-meter total length. Its miniature coaxial ClickLoc connector with protector and FluidLoc cable ensure reliable signal transmission in harsh environments. Built for durability, it features a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case, operating across a wide temperature range of -52°C to +177°C. This model is engineered to prevent common failure modes such as pressure seal leaks and cable damage, making it a trusted choice for vibration and position sensing.

Real-World Applications and Failure Prevention
The Bently Nevada 330707-00-62-50-11-05 is ideal for monitoring shaft vibration and position in turbines, compressors, pumps, and motors. Its armored cable and FluidLoc design resist abrasion and fluid ingress, preventing early failures common in high-vibration environments. The Viton O-ring pressure seal maintains integrity against differential pressure, avoiding costly unplanned downtime. For example, in a steam turbine application, this probe's wide temperature range and robust materials ensure accurate data even near hot casings.
Installation Guidance for Reliable Operation
When installing the Bently Nevada 330707-00-62-50-11-05, follow these best practices. Use the recommended torque of 15.2 N·m for the probe case to avoid thread damage. Ensure thread engagement does not exceed 0.750 in for 1/2-20 threads or 24 mm for M16x1.5. Connect the ClickLoc connector finger tight to 0.565 N·m maximum. Observe the minimum bend radius of 25.4 mm to prevent cable kinking. For probes used below -34°C, note potential pressure seal issues; pre-condition if possible.
Maintenance and Reliability Tips
To maximize the service life of your Bently Nevada 330707-00-62-50-11-05, inspect the cable and connector for wear during routine maintenance. Verify resistance values periodically: expect 7.2 ± 0.8 Ω from center to outer conductor for a 5m probe. Replace if readings drift beyond tolerance. The PPS tip resists chemical attack but avoid contact with concentrated acids. The stainless steel case handles most industrial environments, but in highly corrosive areas, additional shielding may be considered.
Selection Guide for the Bently Nevada 330707-00-62-50-11-05
When selecting this probe, verify your system's total length requirement—the 5.0-meter version is matched with a 5-meter Proximitor sensor. Ensure the thread type (1/2-20 UNF or M16x1.5) fits your mounting. If your application demands higher temperature or pressure, consult the custom design department.
