Product Introduction
When machine vibration monitoring demands uncompromising reliability, the Bently Nevada 330141-08-50-02-05 3300 XL 8 mm probe with armor delivers precise measurements in harsh industrial environments. This eddy-current probe is engineered to withstand physical abuse, fluid ingress, and extreme temperatures, ensuring accurate data for predictive maintenance programs.
The 330141-08-50-02-05 features a patented TipLoc molding method that creates a robust bond between the probe tip and body, while the CableLoc design provides 330 N (75 lbf) pull strength. An optional FluidLoc cable prevents oil and liquids from leaking through the cable interior—critical for applications involving lubricated machinery.

Installation and Setup Guidance
Mount the 330141-08-50-02-05 probe in a threaded hole with proper clearance to the target surface. Ensure the probe tip is perpendicular to the shaft and within the specified gap range (typically 0.25–2.5 mm for 8 mm probes). Use the miniature coaxial ClickLoc connector for secure cable attachment; no special tools needed. The 5-meter cable is intended exclusively for use with the corresponding 5-meter Proximitor sensor—do not mix cable lengths. Armor provides extra protection in abrasive environments.
Maintenance and Reliability
Regularly inspect the probe cable for cuts or abrasions, especially near the connector and the probe tip. The patented TipLoc and CableLoc designs reduce the risk of internal breakage, but periodic visual checks are recommended. Avoid exposing the probe to temperatures below –34°C (–30°F) as this may cause premature failure of the pressure seal. In humid or fluid-prone areas, consider the optional FluidLoc cable upgrade to prevent oil wicking. When cleaning, use only mild solvents; avoid abrasive materials that could damage the PPS tip.
Selection Guide and Purchasing Advice
Before ordering the Bently Nevada 330141-08-50-02-05, verify compatibility with your existing 3300 XL system. This probe works exclusively with 5-meter Proximitor sensors. For applications requiring extended temperature ratings or fluid resistance, ensure that the appropriate options are selected.
