Description

Technical Overview

The Bently Nevada 330102-04-16-10-02-00 is a high-precision, non-contact eddy-current proximity probe engineered for continuous, real-time monitoring of shaft vibration, axial position, and differential expansion in critical rotating machinery. Manufactured by Baker Hughes (formerly Bently Nevada), a global leader in condition monitoring and predictive maintenance solutions, this probe is part of the industry-standard 3300 XL series—renowned for exceptional stability, repeatability, and immunity to environmental interference. Designed specifically for integration with the 3300 XL 8 mm sensor system architecture, the probe delivers linear output over its calibrated range with minimal temperature drift and robust electromagnetic compatibility (EMC). Its stainless steel housing, hermetically sealed construction, and optimized coil geometry ensure long-term reliability in harsh industrial environments—including high-vibration zones, elevated ambient temperatures (up to +121 °C), and exposure to oil, steam, and corrosive process media. The probe operates on the fundamental principle of eddy-current displacement measurement: as the target shaft (typically 4140 or 4340 steel) moves relative to the probe tip, changes in the magnetic field induce proportional variations in impedance, which are converted into a highly accurate DC voltage signal (−2 to −18 V DC) via the associated 3300 XL extension cable and monitor. This model is supplied new and factory-certified, meeting all applicable IEC 61000-4, ISO 10816, and API 670 (4th Edition) standards for machinery protection systems. Backed by a comprehensive 24-month limited warranty, it guarantees performance consistency across its entire service life.

Detailed Specifications
