Bently Nevada 330101-10-27-05-02-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Product Overview

The Bently Nevada 330101-10-27-05-02-05 is a 3300 XL 8 mm probe designed for reliable vibration and position measurement in critical rotating machinery. This probe features a 3/8-24 UNF thread, without armor, making it suitable for standard mounting configurations. Its robust construction includes a patented TipLoc molding method for a stronger bond between the probe tip and body, and a CableLoc design providing 330 N (75 lbf) pull strength. The 8 mm probe offers a thicker encapsulation of the probe coil in molded PPS plastic, resulting in enhanced ruggedness against physical abuse. With a linear range of 2 mm (80 mils) and an incremental scale factor of 7.87 V/mm (200 mV/mil) ±5% (standard 5 or 1 meter system), this probe delivers precise measurements for machinery protection and condition monitoring.

Technical Specifications Breakdown

Key parameters for the 330101-10-27-05-02-05 are listed below for quick reference:

Industry Applications

Compared to smaller 5 mm probes, the 8 mm design offers greater robustness and resistance to physical damage, reducing downtime in harsh environments. The CSA, ATEX, and IECEx approvals allow deployment in hazardous areas, ensuring compliance with international safety standards.

Installation & Setup Guidance

When installing, ensure the probe case thread (3/8-24 UNF) is engaged correctly. Maximum thread engagement length is 0.563 in. For standard forward mounted probes, apply recommended torque of 11.2 N•m (100 in•lbf) for the probe case, and 7.5 N•m (66 in•lbf) for the first three threads. 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. Recommended gap setting for radial vibration is -9 Vdc (approximately 1.27 mm or 50 mils).

Maintenance & Reliability

The probe is designed for long-term reliability. The patented CableLoc design provides 330 N (75 lbf) pull strength, reducing cable failures. The Viton® O-ring seals differential pressure between the probe tip and case. For extended temperature range probes, the tip can withstand -52°C to +218°C (-62°F to +425°F). Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure. Periodic inspection of the cable and connector is recommended.

Compatibility & Integration

This probe is part of the 3300 XL system and is compatible with 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures secure, quick connections. The system supports standard 5 or 1 meter configurations, with incremental scale factor accuracy of ±5%. For 9 meter systems, accuracy is ±6.5%. The probe works with most Bently Nevada monitors and can be integrated into existing machinery protection systems.

Selection Guide & Purchasing Advice

When selecting a probe, consider the required cable length, thread type, and environmental approvals. For armored versions or different cable lengths, consult AutoDCSTech for alternatives. We recommend verifying current lifecycle status and availability before ordering. AutoDCSTech offers genuine Bently Nevada parts with expert support to ensure correct selection.
