Bently Nevada 330101-16-28-10-12-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread, Without Armor

Product Overview

The Bently Nevada 330101-16-28-10-12-CN is a 3300 XL 8 mm probe with a 3/8-24 UNF thread, supplied without armor. This probe is designed for non-contact vibration and position measurement of rotating shafts. Key features include a patented TipLoc molding method for a robust bond between probe tip and body, and a CableLoc design providing 330 N (75 lbf) pull strength. The probe also offers an optional FluidLoc cable to prevent oil leakage through the cable interior. The 8 mm diameter provides thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged probe compared to smaller sizes.

Technical Specifications Breakdown

Key parameters for the 330101-16-28-10-12-CN are listed below for quick reference:

Industry Applications

The 8 mm rugged design and FluidLoc cable make it suitable for applications where oil mist or liquid ingress is a concern, such as in oil and gas refineries or chemical processing plants. The high pull strength (330 N) ensures reliable operation in high-vibration environments, reducing the risk of cable detachment and unplanned downtime.

Installation & Setup Guidance

When installing the 330101-16-28-10-12-CN, ensure the target surface is clean and free of magnetic irregularities. 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. Maximum field wiring length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). For optimal frequency response, refer to the frequency response graphs in the product manual.

Maintenance & Reliability

The probe's PPS tip and stainless steel case provide chemical resistance and mechanical durability. The patented TipLoc and CableLoc designs enhance long-term reliability. Inspect the probe cable and connector periodically for signs of wear or damage, especially in high-temperature or high-humidity environments. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; contact the custom design department if pressure testing is required for your application.

The Evolution of Precision Vibration Monitoring

Industrial machinery has evolved from simple rotating assemblies to complex, high-speed systems where even micron-level displacements can signal impending failure. Early vibration probes offered basic readings but lacked the robustness and accuracy needed for modern predictive maintenance. The Bently Nevada 3300 XL series represents a significant leap forward, combining patented mechanical designs with proven eddy-current technology. The 330101-16-28-10-12-CN is a direct result of this evolution, engineered for demanding environments where reliability and repeatability are non-negotiable.

Compatibility & Integration

This probe is part of the 3300 XL system and is compatible with Bently Nevada 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures a secure, quick connection.

Selection Guide & Purchasing Advice

When selecting a probe, consider the required unthreaded length, overall case length, and total length. The 330101-16-28-10-12-CN offers a 1.0 meter total length with a 1.6 in unthreaded section and 2.8 in overall case.
