Description

Technical Overview

The Bently Nevada 330103-00-04-20-02-05 is a high-precision, industrial-grade proximity probe engineered for continuous, non-contact vibration and displacement monitoring in critical rotating machinery applications. Manufactured by Baker Hughes (under the Bently Nevada brand—a globally recognized leader in condition monitoring and predictive maintenance solutions), this probe belongs to the trusted 3300 XL 8 mm series, renowned for its exceptional stability, repeatability, and immunity to environmental interference. Designed specifically for integration with the 3300 XL 8 mm Proximitor® transducer systems, the probe delivers linear output proportional to target displacement within a calibrated range of ±2.0 mm (±0.079 in), enabling accurate shaft position, vibration amplitude, and gap voltage measurements essential for asset health assessment. The probe features a robust stainless steel housing with a chemically resistant PTFE-insulated coaxial cable, ensuring long-term reliability in harsh environments—including exposure to oil, steam, high temperatures (up to +121°C / +250°F at the probe tip), and electromagnetic noise. Each unit undergoes rigorous factory calibration against NIST-traceable standards and is supplied with full certification documentation, including sensitivity (7.87 V/mm or 200 mV/mil), linearity error (<±0.5% FS), and thermal drift performance (<0.05%/°C). As a new, factory-fresh component, the 330103-00-04-20-02-05 is backed by a comprehensive 24-month limited warranty covering material defects and workmanship—affirming Bently Nevada’s commitment to operational integrity and lifecycle support. Originating from the United States, this probe adheres to ISO 9001:2015 certified manufacturing protocols and complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emissions) standards, making it suitable for global deployment across energy, power generation, petrochemical, aerospace, and marine propulsion sectors.
