Bently Nevada 330101-46-65-10-02-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Technical Specifications Breakdown

Key parameters for the 330101-46-65-10-02-CN are listed below for quick reference:

Industry Applications

Its 2 mm linear range and high sensitivity (7.87 V/mm) allow early detection of shaft displacement, enabling predictive maintenance that reduces unplanned outages. The robust PPS tip and stainless steel case withstand harsh conditions, making it suitable for oil and gas, power generation, and petrochemical facilities.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread into a properly tapped hole. Ensure the target surface is clean and within the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration. Use 3-conductor shielded triad cable for field wiring, with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and monitor. Verify the cable capacitance (69.9 pF/m typical) to maintain signal integrity.

Maintenance & Reliability

The patented TipLoc and CableLoc designs provide enhanced mechanical strength, with 330 N (75 lbf) pull strength for the cable. Inspect the probe and cable periodically for physical damage, especially in high-vibration or high-temperature areas. The probe operates reliably from -52°C to +177°C (standard) and can withstand up to 93% humidity with less than 3% change in Average Scale Factor.

Solving Vibration Monitoring Challenges with Precision

In rotating machinery, undetected vibration can lead to catastrophic failure and costly downtime. The Bently Nevada 330101-46-65-10-02-CN 3300 XL 8 mm Probe addresses this challenge head-on, providing accurate, reliable displacement measurements for critical assets like turbines, compressors, and pumps. Designed with a 3/8-24 UNF thread and without armor, this probe is built for demanding industrial environments where precision and durability are non-negotiable.

Compatibility & Integration

This 3300 XL probe is designed for use with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures secure, quick connections. For optimal performance, pair with compatible monitors that accept -1 to -17 Vdc input from the linear range.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF) and total length (1.0 metre) match your application.
