Product Overview
This proximity probe is part of the Bently Nevada 3300 XL series, designed for non-contact measurement of shaft position and vibration. The 330102-00-80-10-02-00 features a 1.0 meter (3.3 feet) total length, a miniature coaxial ClickLoc connector with standard cable, and a probe case made of AISI 303 or 304 stainless steel. The probe tip is constructed from polyphenylene sulfide (PPS) for durability. It uses a 3/8-24 UNF thread with armor and has an unthreaded length of 0.3 inches and an overall case length of 8.0 inches. Agency approval option is not required for this configuration.

Industry Applications
This probe is well-suited for radial vibration and thrust position monitoring in steam turbines, centrifugal compressors, and large pumps. Its 2 mm linear range and -9 Vdc recommended gap setting enable precise measurement of shaft motion within tight clearances. The stainless steel case and PPS tip provide corrosion resistance in harsh environments.
Installation & Setup Guidance
When installing, ensure the probe tip is positioned within the linear range (0.25 to 2.3 mm from the target). Use the recommended gap setting of -9 Vdc for radial vibration applications. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned wiring. Maximum cable length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). Note the thread engagement limit: maximum 0.563 inches for the 3/8-24 thread.
Maintenance & Reliability
Inspect the probe cable and connector periodically for wear or damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe is designed to seal differential pressure between tip and case using a Viton® O-ring; contact Bently Nevada if pressure testing is required.
Why Do Unplanned Downtime Events Persist in Rotating Machinery?
Many plant engineers face unexpected vibration-related failures that could have been detected earlier. The Bently Nevada 330102-00-80-10-02-00 3300 XL 8 mm Proximity Probe offers a proven solution for continuous shaft displacement and vibration monitoring in critical turbomachinery.
Compatibility & Integration
This probe works with Bently Nevada 3300 XL Proximitor Sensors and monitors. For intrinsically safe installations, use with approved zener barriers per drawing 141092 or galvanic isolators (Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga). For non-incendive circuits, follow drawing 140979 (Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc).
Selection Guide & Purchasing Advice
When selecting a replacement probe, verify the thread size, cable length, and connector type match your existing system. The 330102-00-80-10-02-00 is a standard configuration with 1.0 meter cable and ClickLoc connector. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
