Bently Nevada 330104-08-14-10-02-05 3300 XL 8 mm Proximity Probe with CSA, ATEX, IECEx

Product Overview

When reliable vibration monitoring is critical, the Bently Nevada 330104-08-14-10-02-05 3300 XL 8 mm proximity probe delivers precise measurements in demanding industrial environments. This metric-threaded probe, part of the trusted 3300 XL series, features an M10 x 1 thread with armor for enhanced durability. Designed for radial vibration and position sensing, it offers a linear range of 2 mm (80 mils) starting at approximately 0.25 mm (10 mils) from the target. The probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel (SST), ensuring long-term reliability.

Technical Specifications Breakdown

Understanding key parameters helps you select the right probe for your application. The 330104-08-14-10-02-05 includes an unthreaded length of 80 mm, an overall case length of 140 mm, and a total length of 1.0 meter (3.3 feet). It uses a miniature coaxial ClickLoc connector with standard cable. The nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 m length. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). Temperature range for the standard probe is -52°C to +177°C (-62°F to +350°F). The probe also meets agency approvals including CSA, ATEX, and IECEx.

Industry Applications

This proximity probe excels in rotating machinery monitoring, such as turbines, compressors, and pumps. In oil and gas facilities, the 330104-08-14-10-02-05 provides accurate shaft vibration and position data, helping prevent unplanned downtime. Its robust construction withstands harsh conditions, including high humidity—less than a 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC standard 68-2-3 for up to 56 days. For safety-critical zones, the probe supports intrinsically safe installations when used with zener barriers or galvanic isolators, making it suitable for Class I, Zone 0 environments.

Installation & Setup Guidance

Proper installation ensures optimal performance. The probe case thread is M10x1, with a maximum thread engagement length of 15 mm. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) wire, preferably a 3-conductor shielded triad cable with tinned ends. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Be aware that exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Always follow the manufacturer's guidelines for gap setting and wiring.

Maintenance & Reliability

Routine inspection of the probe and cable connections helps maintain measurement accuracy. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring, but it is not pressure tested before shipment. If your application requires a pressure seal test, contact the custom design department. The probe's PPS tip and stainless steel case resist corrosion and wear, contributing to a long service life. For extended temperature ranges, the probe tip can operate up to +218°C (+425°F), and the cable up to +260°C (+500°F).

Buying Guide & Selection Advice

Before purchasing the 330104-08-14-10-02-05, verify your system requirements: thread type (M10x1), cable length (1.0 m), connector style (miniature coaxial ClickLoc), and agency approvals (CSA, ATEX, IECEx). Ensure compatibility with your 3300 XL Proximitor Sensor and monitor. For current lifecycle status and availability, please verify with plcmatrix.com before ordering.
