Description
Overview
The Emerson PR6426/000‑121 CON031 is an eddy‑current vibration and displacement sensor designed for high‑accuracy, non‑contact monitoring of rotating machinery. As part of the PR6426 series, it provides stable, real‑time measurement of shaft movement, supporting machinery protection and predictive maintenance programs in demanding industrial environments.
Functional Characteristics
This sensor operates as a core component of an eddy‑current measurement chain, detecting minute changes in shaft position and vibration amplitude. Its fast response and high sensitivity enable early identification of mechanical issues such as imbalance, misalignment, and bearing degradation.
The PR6426/000‑121 CON031 is engineered for long‑term reliability. Its rugged construction withstands extreme temperatures, oil contamination, corrosive atmospheres, and continuous mechanical vibration. When paired with the CON031 signal converter, it delivers conditioned output signals compatible with AMS 6500 Classic and EPRO monitoring systems.
