Description
Overview
The Bently Nevada 330101‑00‑20‑15‑12‑05 proximity probe is part of the 3300 XL 8 mm transducer family, engineered for precise non‑contact measurement of shaft vibration and position in rotating machinery. When paired with its extension cable and Proximitor sensor, it forms a complete measurement chain designed for high‑accuracy monitoring in demanding industrial environments.
Design and Operating Principles
This probe detects the distance between its tip and a conductive target surface, producing a voltage output proportional to both static shaft position and dynamic vibration amplitude. The 330101‑00‑20‑15‑12‑05 is suitable for fluid‑film bearing machines and supports Keyphasor reference and speed measurement applications.
The probe assembly complies with API 670 requirements for linearity, temperature stability, and system configuration. Its mechanical and electrical characteristics ensure consistent performance across a wide operating range.
