Description

Technical Overview

The Bently Nevada 330101-00-32-10-02-00 is a high-precision, industrial-grade proximity probe engineered as part of the trusted 3300 XL family. Manufactured by Baker Hughes (formerly Bently Nevada), a global leader in machinery protection and condition monitoring systems, this 8 mm diameter probe delivers exceptional accuracy, stability, and repeatability for non-contact vibration, displacement, and position measurements in demanding rotating equipment environments. Designed specifically for integration with the 3300 XL monitoring system architecture, the probe operates on eddy-current principles to detect minute changes in the distance between its tip and a conductive target surface—typically ferromagnetic shafts or thrust collars. Its robust construction features a stainless steel housing, PTFE-insulated coaxial cable, and hermetically sealed sensing element, ensuring long-term reliability under extreme thermal, mechanical, and electromagnetic conditions. The probe is supplied new and factory-calibrated to meet API 670 (4th Edition) and ISO 10816 standards for machinery protection systems. Each unit undergoes rigorous performance validation—including linearity verification across its full 2 mm linear range, temperature drift compensation testing from –30 °C to +120 °C, and EMI/RFI immunity certification per IEC 61000-4 series. With its optimized frequency response (0–10 kHz bandwidth), low phase shift, and minimal thermal drift (< ±0.5% FS/°C), the 330101-00-32-10-02-00 serves as a foundational sensor in mission-critical asset health management strategies across oil & gas, power generation, petrochemical, and marine propulsion sectors.
