Bently Nevada 330101-29-52-10-02-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Product Overview

The 330101-29-52-10-02-05 is a 3300 XL 8 mm probe with a 3/8-24 UNF thread, supplied without armor. It is manufactured by Bently Nevada in the U.S.A. The probe uses a patented TipLoc molding method for a stronger bond between the probe tip and body, and a CableLoc design provides 330 N (75 lbf) pull strength to secure the cable and tip. An optional FluidLoc cable option prevents oil leakage through the cable interior. The 8 mm probe body offers a thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged sensor suitable for demanding industrial applications.

Technical Specifications Breakdown

Key parameters for the 330101-29-52-10-02-05 are listed below for quick reference:

Industry Applications

The 2 mm linear range and high sensitivity (7.87 V/mm) enable precise detection of shaft displacement, helping operators avoid unplanned downtime. The rugged 8 mm design withstands physical abuse in heavy industrial environments, reducing replacement frequency and total cost of ownership.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread into a suitable mounting 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 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).

Maintenance & Reliability

Inspect the probe cable and connector 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 pressure seal failure. The probe exhibits less than a 3% change in Average Scale Factor when tested in 93% humidity per IEC standard 68 2 3 for up to 56 days.

The Evolution of Precision Vibration Monitoring

Industrial machinery has grown more complex over the decades, demanding sensors that keep pace with tighter tolerances and harsher environments. The Bently Nevada 330101-29-52-10-02-05 represents a significant step forward in eddy-current probe technology, building on decades of field experience to deliver reliable shaft vibration and position measurements. This 3300 XL 8 mm probe is engineered for robustness without compromising accuracy, making it a trusted choice for critical rotating equipment.

Compatibility & Integration

The 330101-29-52-10-02-05 is compatible with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. It uses a miniature coaxial ClickLoc connector for secure attachment. The probe is approved under CSA, ATEX, and IECEx schemes, making it suitable for hazardous area installations.

Selection Guide & Purchasing Advice

When selecting a replacement probe, verify the unthreaded length (2.9 in), overall case length (5.2 in), and total cable length (1.0 metre). The 330101-29-52-10-02-05 is available from AutoDCSTech. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
