Product Overview

The 330101-00-33-05-02-00 is a precision eddy current sensor belonging to the Bently Nevada 3300 XL 8mm series. This transducer is engineered for non-contacting displacement measurements, providing critical data on shaft vibration and axial position for high-speed rotating machinery. By generating a high-frequency electromagnetic field, the probe detects minute changes in the gap between the probe tip and a conductive target. This specific model is built to comply with API 670 standards, ensuring high-tier accuracy, linear range stability, and thermal resistance in demanding industrial environments such as power plants and refineries.

Technical Configuration

This probe is defined by a specific set of mechanical and electrical parameters tailored for localized machine casing mounting:

• Model Number: 330101-00-33-05-02-00

• Thread Type: 3/8-24 UNF standard thread

• Unthreaded Length: 0.0 inches (Fully threaded body)

• Total Case Length: 3.3 inches

• Integrated Cable Length: 0.5 meters (1.6 feet)

• Connector Type: Miniature coaxial ClickLoc connector

• Agency Approval: No specialized hazardous area approvals (standard version)

• Mounting Configuration: Without armor

• Net Weight: 0.06 kg

Advanced Engineering and Integration

The 330101-00-33-05-02-00 is designed for complete interchangeability within the 3300 XL ecosystem. It features a polyphenylene sulfide (PPS) tip that is resistant to corrosive fluids and high temperatures, maintaining a hermetic seal against oil penetration. The ClickLoc connector utilizes a gold-plated interface that resists vibration-induced signal noise and corrosion. This probe is optimized for use with the 3300 XL Proximitor Sensor, but it maintains backward compatibility with legacy 3300 series systems, allowing for cost-effective hardware upgrades without replacing existing cabling infrastructures.

Industrial Applications

As a core element of Turbine Supervisory Instrumentation (TSI), this probe is used for:

• Monitoring radial vibration in fluid-film bearings.

• Measuring axial thrust position to prevent rotor-to-stator contact.

• Detecting eccentricity in large steam and gas turbines.

• Serving as a Keyphasor reference for speed measurement and phase-angle detection.

• Protective monitoring of centrifugal compressors and industrial pumps.
