Bently Nevada 330101-39-63-10-02-CN 3300 XL 8 mm Probe without Armor

Technical Specifications Breakdown

Key parameters for the 330101-39-63-10-02-CN are listed below for quick reference:

Industry Applications

This probe is ideally suited for monitoring radial vibration in steam turbines, compressors, pumps, and electric motors. Its 8 mm diameter provides a thicker encapsulation of the probe coil in molded PPS plastic, offering enhanced robustness against physical abuse. The 1.0 metre cable with miniature coaxial ClickLoc connector simplifies installation in confined spaces. For applications where oil or liquid leakage through the cable interior is a concern, the optional FluidLoc cable variant can be specified.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread into a drilled and tapped hole per manufacturer guidelines. 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 measurements. Field wiring should use 3-conductor shielded triad cable with tinned conductors, sized 0.2 to 1.5 mm² (16 to 24 AWG). Maximum field wiring length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). Refer to frequency response graphs for signal rolloff at high frequencies when using longer cable runs.

Maintenance & Reliability

The probe’s stainless steel case (AISI 303 or 304) resists corrosion in industrial environments. The patented CableLoc design provides 330 N (75 lbf) pull strength, securing the cable and tip. For standard probes, the operating and storage temperature range is -52°C to +177°C. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Inspect the probe and cable periodically for physical damage and ensure connectors are clean and tight.

Robust Vibration Sensing for Critical Machinery

Industrial rotating machinery demands precise, reliable vibration monitoring to prevent costly downtime and catastrophic failures. The Bently Nevada 330101-39-63-10-02-CN is a 3300 XL 8 mm probe designed to deliver accurate displacement measurements in harsh environments. This probe features a 3/8-24 UNF thread and is supplied without armor, making it suitable for applications where direct mounting is preferred. Its patented TipLoc and CableLoc technologies enhance mechanical integrity, ensuring consistent performance over extended periods.

Compatibility & Integration

This probe is part of the 3300 XL system and is compatible with Bently Nevada Proximitor Sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure, quick connection. The probe is designed for use with extension cables that have a typical capacitance of 69.9 pF/m (21.3 pF/ft).

Selection Guide & Purchasing Advice

When selecting a vibration probe, consider the machine’s operating temperature, required cable length, and mounting thread. The 330101-39-63-10-02-CN offers a 1.0 metre cable and standard temperature range. For extended temperature applications (probe tip up to +218°C), order the ETR version.
