The Bently Nevada 330101-00-15-10-02-05 is a high-precision 3300 XL 8 mm proximity probe engineered for non-contact measurement of shaft vibration, position, and eccentricity in industrial rotating machinery. As a core component of the 3300 XL transducer system, this probe utilizes eddy-current technology to provide reliable, continuous monitoring of shaft motion, supporting critical machinery protection and diagnostic functions.

Features

• Eddy-Current Sensing: Provides accurate, non-contact measurement of dynamic (vibration) and static (position) parameters.
• Robust Construction: Features a 3/8-24 UNF threaded body with a 1.5-inch case length and a 1.0-meter integrated cable.
• Advanced Design: Incorporates TipLoc and CableLoc technologies to ensure a secure, durable bond between the probe tip, body, and cable.
• Interchangeability: Fully compatible with other 3300 XL series components and backward compatible with non-XL 3300 series 5 mm and 8 mm systems.
• System Integration: Designed for use with 3300 XL Proximitor sensors and extension cables to form a complete, calibrated transducer loop.

Applications

• Gas & Steam Turbines: Monitoring shaft vibration, thrust, and differential expansion.
• Centrifugal Compressors: High-speed monitoring for refinery and pipeline operations.
• Hydroelectric Generators: Tracking rotor movement and vibration.
• Industrial Pumps & Motors: Detecting mechanical seal or bearing wear in critical process equipment.
• Gearboxes: Monitoring shaft alignment and vibration in heavy-duty drive trains.

Technical Specifications

Installation Guidelines

• Handling: Ensure the probe tip is protected from impact. Use ESD-safe practices during installation.
• Mounting: Maintain a minimum side-view clearance (counterbore) of 13 mm (0.5 in) to prevent interference from housing walls.
• Gap Setting: For radial vibration, set the initial gap to 1.27 mm (50 mils), corresponding to approximately -9 Vdc.
• Connections: Use finger-tight torque for ClickLoc connectors; do not over-tighten with tools.
• Environment: Ensure the installation area is free from excessive metallic debris that could interfere with the eddy-current field.

FAQ

What is the primary function of this probe?

It measures the displacement and vibration of rotating shafts, providing essential data for machinery health monitoring and protection systems.

Is this probe compatible with older 3300 series systems?

Yes, the 3300 XL series is designed to be electrically and physically interchangeable with non-XL 3300 series 5 mm and 8 mm transducer components.

What is the standard operating gap voltage?

When properly installed within its linear range, the probe typically operates at a DC gap voltage between -9 V and -11 V.
