Description
Overview
The Bently Nevada 330101‑00‑18‑20‑12‑05 proximity probe is an 8 mm eddy‑current sensor designed for accurate non‑contact measurement of shaft vibration and displacement. As part of the 3300 XL Proximity Transducer System, it provides stable linearity, long‑term durability, and dependable performance in demanding industrial environments.
Design and Construction
This probe delivers an electrical output proportional to the distance between the probe tip and a conductive target surface, enabling precise monitoring of both static shaft position and dynamic vibration. It is widely used in fluid‑film bearing machines, turbine supervisory systems, and general rotating equipment.
The 330101‑00‑18‑20‑12‑05 is engineered for full compatibility with 3300 XL extension cables and Proximitor sensors. Its interchangeable design eliminates the need for component matching or bench calibration, simplifying installation and maintenance.
A rugged probe body, reinforced cable construction, and high‑quality molded tip ensure long‑term reliability in harsh operating conditions. This model is suitable for applications requiring consistent measurement accuracy and robust mechanical performance.
