Bently Nevada 330101-00-24-10-01-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Selecting the Right Vibration Probe for Your Machinery

When protecting critical rotating assets, choosing the correct proximity probe is essential for accurate vibration and position monitoring. The Bently Nevada 330101-00-24-10-01-CN offers a proven solution for demanding industrial environments. This 3300 XL 8 mm probe, with its 3/8-24 UNF thread and robust design, provides reliable performance for continuous machine protection.

Technical Specifications Breakdown

Key parameters for the 330101-00-24-10-01-CN are listed below for quick reference:

Application-Specific Benefits for Rotating Machinery

The 8 mm diameter provides a thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged probe that withstands physical abuse. The patented TipLoc molding method ensures a robust bond between the probe tip and body, while the CableLoc design delivers 330 N (75 lbf) pull strength for secure cable attachment. These features reduce the risk of probe damage during installation or operation, lowering total cost of ownership.

Installation and Setup Guidance

For optimal performance, mount the probe using the 3/8-24 UNF thread into a suitable mounting fixture. The recommended gap setting for radial vibration is -9 Vdc (approximately 1.27 mm or 50 mils). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and the target surface is smooth and free of electrical runout.

Maintenance and Reliability Considerations

Inspect the probe and cable periodically for signs of wear or damage. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring; avoid exposing the probe to temperatures below –34°C (–30°F) to prevent premature failure of the pressure seal. For applications with high humidity, note that the probe shows 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 series and is compatible with 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector simplifies field installation and provides a secure connection. The standard cable length of 1.0 meter (3.3 feet) allows flexible routing to the extension cable.

Purchasing Advice from AutoDCSTech

When selecting a probe, verify the total length, thread size, and connector type match your system requirements. The 330101-00-24-10-01-CN is a standard configuration without armor, suitable for most industrial environments. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
