Bently Nevada 330101-00-39-15-11-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Robust Vibration Monitoring with the Bently Nevada 330101-00-39-15-11-CN

Industrial rotating machinery demands precise and reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 330101-00-39-15-11-CN is a 3300 XL 8 mm probe designed for eddy-current displacement measurement in harsh environments. This probe, featuring a 3/8-24 UNF thread and without armor, provides the accuracy and durability needed for critical asset protection.

Technical Specifications Breakdown

Key parameters for the 330101-00-39-15-11-CN are listed below for quick reference:

Industry Applications for the 3300 XL Probe

The 8 mm diameter provides enhanced robustness against physical abuse compared to smaller probes. The patented TipLoc and CableLoc designs ensure a secure bond and high pull strength (330 N / 75 lbf), reducing the risk of signal loss in high-vibration environments. The FluidLoc cable option prevents oil leakage through the cable interior, making it suitable for lubricated machinery.

Installation and Setup Guidance

When installing the 330101-00-39-15-11-CN, ensure the probe tip is clean and the mounting surface is free of debris. The recommended gap setting for radial vibration is -9 Vdc (approximately 1.27 mm / 50 mils). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable, keeping the maximum length between the Proximitor Sensor and monitor at 305 meters (1,000 feet). For optimal performance, avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.

Maintenance and Reliability

Periodically inspect the probe cable and connector for signs of wear or damage. The probe is designed to seal differential pressure using a Viton O-ring; however, it is not pressure tested before shipment. If your application requires pressure seal verification, contact the custom design department. The probe operates reliably in high humidity environments (less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3).

Compatibility and Integration

This probe is part of the 3300 XL system and is compatible with 3300 XL Proximitor Sensors and extension cables. The miniature coaxial ClickLoc connector ensures a secure, quick connection. For extended temperature range applications, the probe tip can withstand up to +218°C (+425°F) and the cable up to +260°C (+500°F).

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF) and cable length (1.5 meters). The 330101-00-39-15-11-CN is available from AutoDCSTech, a trusted supplier of industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
