Bently Nevada 330101-00-50-20-02-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Optimized Vibration Monitoring with the Bently Nevada 3300 XL 8 mm Probe

For engineers tasked with protecting critical rotating machinery, the Bently Nevada 330101-00-50-20-02-CN provides a proven solution for accurate and reliable vibration measurement. This 3300 XL 8 mm probe, featuring a 3/8-24 UNF thread and designed without armor, is engineered for direct installation into bearing housings and machine casings. Its robust construction minimizes the risk of physical damage, ensuring consistent performance in demanding industrial environments.

Technical Specifications Breakdown

Key parameters for the 330101-00-50-20-02-CN are listed below for quick reference:

Industry Applications for the 3300 XL Probe

Its 2 mm linear range and 7.87 V/mm scale factor provide precise displacement data for predictive maintenance programs. In petrochemical and power generation facilities, the probe's robust PPS tip and stainless steel case withstand harsh conditions, reducing unplanned downtime. The 330101-00-50-20-02-CN is particularly suited for installations where space is limited, thanks to its compact 8 mm diameter.

Installation & Setup Guidance

Proper installation is critical for accurate readings. The 3/8-24 UNF thread allows secure mounting into standard tapped holes. Use the recommended torque values to avoid damaging the probe or housing: for forward mounted probes, apply 11.2 N•m (100 in•lbf) for the case, and 7.5 N•m (66 in•lbf) for the first three threads. The recommended gap setting for radial vibration is -9 Vdc, corresponding to approximately 1.27 mm (50 mils). Ensure the target surface is clean and within the specified linear range.

Maintenance & Reliability

The patented TipLoc and CableLoc designs enhance mechanical integrity, providing 330 N (75 lbf) pull strength. For extended life, avoid exposing the probe to temperatures below –34˚C (–30˚F) to prevent premature pressure seal failure. Periodically inspect the cable and connector for wear. The probe's Viton® O-ring seals differential pressure, but it is not pressure tested before shipment; contact the manufacturer if your application requires a pressure seal test.

Compatibility & Integration

This probe is designed for use with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures a secure, noise-resistant connection. Field wiring between the Proximitor and monitor can be up to 305 meters (1,000 feet) using 3-conductor shielded triad cable. The system delivers a standard incremental scale factor of 7.87 V/mm, ensuring interchangeability with other 3300 XL components.

Selection Guide & Purchasing Advice

When selecting a vibration probe, consider the thread size, cable length, and environmental conditions. The 330101-00-50-20-02-CN offers a 2.0-meter cable and country-specific approvals. For applications requiring higher temperature tolerance, consider the extended temperature range probe option.
