Bently Nevada 330102-36-80-10-02-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330102-36-80-10-02-05 are listed below for quick reference:

Industry Applications and Use Cases

The 8 mm diameter and 2 mm linear range make it suitable for measuring radial vibration and axial position in machines with tight clearance requirements. With CSA, ATEX, and IECEx approvals, it is certified for use in hazardous areas (Class I, Zone 0 and Zone 2) when installed with appropriate intrinsic safety barriers or non-incendive circuits. The PPS tip withstands harsh process conditions, while the stainless steel case resists corrosion.

Installation and Setup Guidance

Proper installation is critical for accurate readings. The probe uses a 3/8-24 UNF thread with a maximum thread engagement of 0.563 inches. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. The maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Set the initial gap to -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration measurements. Always consult the installation manual for specific mounting instructions.

Maintenance and Reliability

This probe is designed for long-term reliability. The Viton® O-ring provides a pressure seal, but probes are not pressure tested before shipment. If your application requires a pressure seal test, contact Bently Nevada's custom design department. The probe operates reliably in up to 93% relative humidity with less than 3% change in Average Scale Factor. For extended temperature ranges, the probe tip can withstand up to +218°C (+425°F) and the cable up to +260°C (+500°F). Periodically inspect the cable and connector for damage, especially in high-vibration environments.

Selecting the Right Proximity Probe for Critical Machinery Protection

When monitoring rotating machinery, the probe is your first line of defense against costly unplanned downtime. The Bently Nevada 330102-36-80-10-02-05 is a 3300 XL 8 mm Proximity Probe designed for reliable, continuous vibration and position measurement in demanding industrial environments. This article helps you evaluate whether this probe meets your application requirements.

Compatibility and Integration

The 330102-36-80-10-02-05 is part of the 3300 XL system and works with Bently Nevada 3300 XL Proximitor Sensors and monitors. The miniature coaxial ClickLoc connector ensures a secure, quick connection. When used with intrinsic safety zener barriers (per drawing 141092) or galvanic isolators, it is suitable for Class I, Zone 0 applications. For non-incendive circuits (per drawing 140979), it can be used in Class I, Zone 2 areas. Always verify compatibility with your existing monitoring system.

Selection Guide and Purchasing Advice

When selecting a proximity probe, consider the required cable length, thread type, and agency approvals. The 330102-36-80-10-02-05 offers a 1.0-meter total length, 3/8-24 UNF thread, and global certifications. For longer cable runs or different connector types, other part number options are available.
