Product Overview

The Bently Nevada 330104-00-10-10-11-00 is a high-precision eddy current proximity probe belonging to the industry-leading 3300 XL 8 mm transducer family. This non-contacting sensor is engineered to measure the gap between the probe tip and a conductive target, typically a rotating shaft. It is a fundamental component for monitoring radial vibration and axial position in machinery equipped with fluid-film bearings. By providing a voltage output proportional to the distance from the target, it allows for the detection of minute mechanical changes, ensuring the operational integrity of high-speed industrial assets. This specific model features a metric M10 x 1 thread and is designed for seamless integration with 3300 XL Proximitor sensors and extension cables.

Operational Use Cases and Industrial Applications

As a primary sensor for Turbine Supervisory Instrumentation (TSI), the 3300 XL 8 mm probe is utilized across various sectors to prevent catastrophic machinery failure.

• Radial Shaft Vibration Monitoring the dynamic oscillation of shafts in turbines and compressors to detect unbalance, misalignment, or bearing degradation.

• Axial Thrust Position Measuring the longitudinal movement of the rotor relative to the thrust bearing to prevent internal mechanical rubs.

• Keyphasor Reference Providing a once-per-turn pulse for phase angle measurements, essential for balancing and sophisticated diagnostic analysis.

• Eccentricity Measurements Detecting rotor bow or thermal warping in large steam turbines during slow-roll startup conditions.

• Critical Asset Protection Implementation on high-pressure pumps, gearboxes, and electric motors in power generation, oil and gas, and petrochemical facilities.
