Product Introduction
When machinery vibration monitoring demands consistent accuracy and durability, the Bently Nevada 330708-00-24-10-02-00 3300 XL 11 mm Proximity Probe delivers. This non-contact sensor measures shaft displacement and vibration in rotating equipment, providing critical data for predictive maintenance. Designed with a Polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case, the Bently Nevada 330708-00-24-10-02-00 withstands harsh industrial environments.

Industry Applications
The Bently Nevada 330708-00-24-10-02-00 3300 XL 11 mm Proximity Probe is ideal for monitoring steam turbines, compressors, pumps, and large electric motors. In a typical turbine train, the probe mounts near the bearing housing to detect shaft orbit and eccentricity. Its wide temperature range (-51°C to +177°C) suits both cold start-ups and high-heat areas. The PPS tip resists chemical attack from lubricants and process fluids, making the Bently Nevada 330708-00-24-10-02-00 suitable for oil & gas and petrochemical applications.
Installation & Setup Guidance
Install the Bently Nevada 330708-00-24-10-02-00 with care. The 5/8-18 UNF thread requires a matching mounting hole. Use the recommended torque of 15.2 N·m (133 in·lb) for the probe case—do not exceed 45.2 N·m (400 in·lb) to avoid thread damage. The miniature coaxial ClickLoc connector (option 02) secures the cable; tighten finger-tight only (max 0.565 N·m / 5 in·lb). Ensure the probe tip does not contact the rotating shaft; maintain the proper gap per the 3300 XL system guidelines. The cable must have a minimum bend radius of 25.4 mm (1.0 in) to prevent internal damage.
Maintenance & Reliability
To extend the life of your Bently Nevada 330708-00-24-10-02-00, inspect the cable and connector periodically. The Viton® O-ring pressure seal can degrade if exposed to temperatures below -34°C (-30°F) for long periods; avoid such conditions to prevent premature seal failure. Check the probe DC resistance at 5.9 ± 0.5 ohms (1m length) as a quick health check. Any deviation may indicate cable damage or moisture ingress. The stainless steel case resists corrosion, but verify that the mounting area stays clean. Following these steps reduces unplanned downtime—a key ROI consideration for continuous processes.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 330708-00-24-10-02-00, verify the total probe length (1.0 meter in this option), connector type (miniature coaxial ClickLoc), and that no special agency approval is needed. This model is unarmored; if your environment has high vibration or sharp edges, consider the armored version. For OEM replacements, cross-check the thread length and case length (2.4 inches overall case length). UBEST Automation stocks genuine Bently Nevada parts to ensure compatibility.
