Description

The Bently Nevada 330709-000-050-10-02-00 is a 3300 XL 11 mm Proximity Probe designed for high-precision, non-contact vibration and position measurements in rotating machinery. As a critical component of the 3300 XL Transducer System, it provides a linear output signal proportional to the distance between the probe tip and the observed conductive surface. This probe is engineered to replace legacy 7200-series 11 mm and 14 mm transducer systems, offering improved RFI/EMI immunity and robust signal integrity.

Features

• Nominal Scale Factor: 3.94 V/mm (100 mV/mil).
• Long linear range of 4.0 mm (160 mils).
• M16 x 1.5 thread configuration for standard mounting.
• Miniature coaxial ClickLoc connector for secure, tool-free installation.
• Advanced RFI/EMI immunity for reliable operation in high-frequency radio environments.
• Compatible with 3300 XL Proximitor Sensors and extension cables.

Applications

• Oil & Gas Refineries and Petrochemical Plants: Monitoring compressors, pumps, and fluid-film bearings.
• Power Generation: Axial and radial vibration monitoring for steam, gas, and hydro turbines.
• Pulp and Paper: Monitoring large rolls and pulp refiners.
• Mining and Metal Processing: Heavy equipment monitoring including ball mills and crushers.
• Water and Wastewater: Critical pump and blower monitoring.

Installation Guidelines

• System Upgrade: When replacing 7200-series systems, all components (probe, extension cable, and Proximitor sensor) must be replaced with 3300 XL 11 mm components.
• Connector Handling: For 3300 XL to 3300 XL connections, tighten finger-tight until a click is felt.
• Mixed Connections: When connecting to non-XL stainless steel connectors, tighten finger-tight and apply an additional 1/8 turn with pliers.
• Torque Limit: Do not exceed 0.565 N-m (5 in-lb) of torque to prevent damage to gold-plated contacts.
• Electrical Health: Verify probe health by measuring DC resistance between center and outer conductors (typically 5.9 ± 0.5 ohms for a 1.0m probe).

FAQs

What is the linear range of this system?

The 3300 XL 11 mm system provides a linear range of 4.0 mm (160 mils).

Does this probe require an extension cable?

Yes, this 1.0-meter probe is designed to be used with a compatible 4-meter or 8-meter extension cable to form a complete, calibrated 5-meter or 9-meter transducer system.
