Product Overview

The Bently Nevada 330101-00-50-10-02-05 is a high-precision 8mm proximity probe specifically engineered for the 3300 XL series monitoring platform. This non-contacting sensor is a cornerstone of Turbine Supervisory Instrumentation (TSI), designed to measure the minute displacement between the probe tip and a conductive target surface. By utilizing eddy-current technology, it provides continuous, high-fidelity data on shaft vibration and axial position. This specific model features a standard 3/8-24 UNF thread with a compact 5.0-inch case length, allowing for precise gap adjustment in critical machinery housings. As a fully interchangeable component, it integrates seamlessly with 3300 XL Proximitor sensors and extension cables without requiring specialized bench calibration.

Strategic Asset Monitoring and Deployment

The 330101-00-50-10-02-05 is the industry standard for safeguarding high-value rotating equipment across the power generation, oil, and gas sectors. It is primarily deployed on machines utilizing fluid-film bearings—such as centrifugal compressors, steam turbines, and large industrial pumps—to monitor radial shaft vibration and axial thrust position. The inclusion of protective armor ensures that the signal path remains intact even in high-vibration and debris-prone environments. Furthermore, this probe is an essential source for Keyphasor signals, providing the phase-reference data required for advanced machinery diagnostics and balancing. By delivering deterministic measurements to Bently Nevada 3500 series monitoring racks, it enables automated safety shutdowns and prevents catastrophic equipment failure.
