Bently Nevada 330102-00-50-10-02-05 3300 XL 8 mm Proximity Probe

Evaluating the Bently Nevada 3300 XL Proximity Probe for Your Vibration Monitoring Needs

When selecting a proximity probe for critical rotating machinery, the Bently Nevada 330102-00-50-10-02-05 offers a specific configuration designed for reliable shaft vibration and position measurement. This guide helps you assess its suitability based on your application requirements.

Product Overview

The 330102-00-50-10-02-05 is a 3300 XL 8 mm proximity probe from Bently Nevada, a trusted brand in industrial vibration monitoring. It features a polyphenylene sulfide (PPS) probe tip and an AISI 303 or 304 stainless steel case. This model includes a 1.0 meter (3.3 feet) cable with a miniature coaxial ClickLoc connector and is approved for hazardous areas with CSA, ATEX, and IECEx certifications. The probe is designed for differential pressure sealing with a Viton O-ring.

Technical Specifications Breakdown

Key parameters for the 330102-00-50-10-02-05 are listed below for quick reference:

Industry Applications

This probe is commonly used in turbomachinery, compressors, and pumps where precise shaft vibration monitoring is critical. The 2 mm linear range and recommended -9 Vdc gap setting make it suitable for radial vibration measurements. The CSA, ATEX, and IECEx approvals allow installation in hazardous environments, reducing the need for additional barriers in many cases. When evaluating cost-benefit, the robust stainless steel case and PPS tip offer long service life in demanding conditions, potentially lowering total ownership costs.

Installation & Setup Guidance

For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) wire with a 3-conductor shielded triad cable. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and the mounting surface is free of debris. The thread engagement limit is 0.563 inches for the 3/8-24 UNF thread. The probe weighs 323 g/m (11.4 oz).

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage. The probe is designed to seal differential pressure with a Viton O-ring; however, it is not pressure tested before shipment. If pressure seal integrity is critical, contact the custom design department. The probe can operate in up to 93% humidity with less than 3% change in Average Scale Factor (ASF) per IEC 68-2-3. For extended temperature range applications, the probe tip can withstand up to +218°C (+425°F) and the cable up to +260°C (+500°F).

Compatibility & Integration

The probe is part of the 3300 XL system and works with compatible Bently Nevada Proximitor sensors and monitors. The miniature coaxial ClickLoc connector ensures secure and quick installation. For intrinsically safe installations, use with approved zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, follow drawing 140979.

Selection Guide & Purchasing Advice

When selecting the 330102-00-50-10-02-05, verify that your application requires an 8 mm probe with a 1.0 meter cable and CSA/ATEX/IECEx approvals. If your needs differ, AutoDCSTech offers a range of Bently Nevada probes with various lengths and connector options.
