Industry Applications for the 330102-00-68-05-02-05
This proximity probe is engineered for continuous vibration monitoring on steam turbines, centrifugal compressors, and large pumps. The 2 mm linear range and -9 Vdc recommended gap setting ensure accurate shaft displacement readings. With CSA, ATEX, and IECEx approvals, the probe suits hazardous environments such as oil & gas refineries and chemical processing plants.

Installation & Setup Guidance
Mount the probe using the 3/8-24 UNF thread with a maximum thread engagement of 0.563 inches. Connect field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) using a 3-conductor shielded triad cable. The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For high-frequency applications, refer to frequency response graphs for signal rolloff. The probe seals differential pressure between tip and case via a Viton O-ring; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.
Maintenance & Reliability
Inspect the probe cable and connector periodically for wear or damage. The PPS tip and stainless steel case resist corrosion in harsh environments. When installed with intrinsic safety barriers per drawing 141092 or with galvanic isolators, the probe meets Class I, Zone 0 requirements. For non-incendive installations, follow drawing 140979.
Precision Vibration Monitoring with the Bently Nevada 3300 XL 8 mm Probe
The Bently Nevada 330102-00-68-05-02-05 is a 3300 XL 8 mm proximity probe designed for reliable shaft vibration and position measurement in critical rotating machinery. This model features a 0.5 meter (1.6 feet) total length, a 6.8 inch overall case length, and a 3/8-24 UNF thread with armor. It comes with a miniature coaxial ClickLoc connector and standard cable, plus agency approvals including CSA, ATEX, and IECEx.

Compatibility & Integration
The 330102-00-68-05-02-05 integrates directly with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures secure signal transmission. The probe is compatible with standard 3-conductor shielded triad cable for field wiring.
Selection Guide & Purchasing Advice
When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), overall case length (6.8 in), and total length (0.5 m). The 330102-00-68-05-02-05 is available now from AutoDCSTech. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
Troubleshooting & Common Issues
If readings are erratic, check the field wiring connections and cable integrity. Ensure the probe gap is set to approximately -9 Vdc (1.27 mm). For high-temperature applications, confirm the extended temperature range cable is used. If the pressure seal fails, contact Bently Nevada custom design department for testing options.
