Bently Nevada 330102-24-72-10-02-00 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330102-24-72-10-02-00 is a 3300 XL 8 mm Proximity Probe with a 3/8-24 UNF thread and armor. It features a 2.4-inch unthreaded length, 7.2-inch overall case length, and a 1.0-meter (3.3 feet) total length with standard cable. The connector is a miniature coaxial ClickLoc type, ensuring secure and quick installation. The probe tip is made of Polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel, providing durability in harsh conditions.

Technical Specifications Breakdown

Key parameters for the 330102-24-72-10-02-00 are listed below for quick reference:

Industry Applications

This probe is commonly used for radial vibration and position monitoring in turbines, compressors, pumps, and other rotating machinery. Its 2 mm linear range and recommended -9 Vdc gap setting make it suitable for detecting shaft displacement and vibration in high-speed equipment. The PPS tip and stainless steel case resist corrosion and wear, extending service life in petrochemical and power generation plants.

Installation & Setup Guidance

For best performance, ensure the probe is installed with the correct gap setting. The recommended gap for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils) from the target. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Note that longer wiring may cause signal rolloff at high frequencies; refer to frequency response graphs for your application.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage. The probe is designed to seal differential pressure between 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. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal.

Choosing the Right Proximity Probe for Critical Machinery Monitoring

When selecting a proximity probe for vibration and position monitoring in rotating machinery, reliability and accuracy are non-negotiable. The Bently Nevada 330102-24-72-10-02-00, a 3300 XL 8 mm Proximity Probe, is engineered to deliver precise measurements in demanding industrial environments. This buyer's guide helps you evaluate whether this probe meets your application requirements.

Compatibility & Integration

The 330102-24-72-10-02-00 is part of the 3300 XL series and works with Bently Nevada Proximitor Sensors and monitoring systems. When installed with intrinsically safe zener barriers or galvanic isolators, it can be used in hazardous locations (Class I, Zone 0, Groups A-G). For non-incendive installations, follow drawing 140979 for Class I, Zone 2 applications.
