Description

Technical Overview

The Bently Nevada 330103-00-05-20-02-00 is a high-precision, industrial-grade proximity probe engineered for continuous, non-contact vibration and displacement monitoring in mission-critical rotating machinery. Manufactured by Baker Hughes under the globally recognized Bently Nevada brand—a leader in asset condition monitoring since 1961—this probe is part of the trusted 3300 XL series, specifically designed to deliver exceptional stability, repeatability, and immunity to environmental interference. As a calibrated 8 mm diameter eddy-current sensor, it operates on the principle of electromagnetic induction to measure dynamic shaft motion relative to a fixed reference point with sub-micron resolution. The probe is supplied as new, factory-fresh inventory with full traceable calibration documentation compliant with ISO 17025 standards. Each unit undergoes rigorous performance validation—including temperature cycling, linearity verification, and frequency response testing—prior to shipment. Backed by a standard 24-month limited warranty covering material defects and workmanship, the 330103-00-05-20-02-00 ensures long-term reliability across demanding operational environments. With its compact cylindrical housing (12.7 mm diameter × 63.5 mm length), lightweight construction (115 g), and robust stainless steel 316L body, the probe is optimized for installation in space-constrained bearing housings and turbine casings. Originating from the United States—Bently Nevada’s primary manufacturing and calibration facility in Minden, Nevada—the probe meets stringent export compliance requirements (EAR99) and adheres to RoHS 3, REACH, and UL 61010-1 safety directives. Its seamless integration with 3300 XL 200/210/220 series monitors, 3500 system racks, and System 1™ diagnostic software enables real-time data acquisition, spectral analysis, and predictive maintenance workflows essential for Industry 4.0 readiness.

Detailed Specifications

Key Features
