Bently Nevada 330102-00-36-05-02-05 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330102-00-36-05-02-05 is a 3300 XL 8 mm Proximity Probe designed for non-contact measurement of shaft position and vibration. It features a 3/8-24 UNF thread with armor, a 0.5 meter cable, and a miniature coaxial ClickLoc connector. The probe tip is made of Polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel. It carries CSA, ATEX, and IECEx approvals for hazardous area use.

Technical Specifications Breakdown

Key parameters for the 330102-00-36-05-02-05 are listed below for quick reference:

Industry Applications

Its 2 mm linear range and -9 Vdc recommended gap setting provide consistent performance for critical machinery protection. The CSA, ATEX, and IECEx approvals allow installation in hazardous areas, making it suitable for oil and gas, petrochemical, and power generation facilities.

Installation & Setup Guidance

When installing the 330102-00-36-05-02-05, ensure the probe tip is clean and the target surface is smooth. The maximum thread engagement length is 0.563 in. Use 3 conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² / 16 to 24 AWG). The maximum field wiring length between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). Refer to frequency response graphs for signal rolloff at high frequencies with longer wiring.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage or contamination. 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 (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days.

The Evolution of Precision Monitoring

Industrial machinery monitoring has advanced from simple vibration checks to sophisticated, continuous condition-based maintenance. The Bently Nevada 3300 XL 8 mm Proximity Probe represents a key component in this evolution, enabling precise shaft displacement and vibration measurements in critical rotating equipment. For engineers tasked with maximizing uptime and avoiding catastrophic failures, this probe offers reliable performance in demanding environments.

Compatibility & Integration

This probe is part of the 3300 XL system and works with compatible Proximitor Sensors and monitors. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, connect per drawing 140979. The probe is rated for Class I, Zone 0 and Zone 2 environments as specified.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size, cable length, and agency approvals match your application. The 330102-00-36-05-02-05 is available from AutoDCSTech, your trusted source for industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If readings are erratic, check the cable and connector for damage or loose connections. Verify the gap voltage is set to the recommended -9 Vdc. Ensure the target material is compatible and the probe tip is not contaminated. For pressure seal concerns, contact the custom design department for testing.
