Description
Product Description
Overview
The Emerson PR6424/000-121 displacement sensor paired with the CON031 signal conditioning module is a high-resolution, compact measurement system engineered for precision monitoring of rotating machinery. Designed for harsh industrial environments, this system delivers accurate non-contact shaft displacement readings and supports both static positioning and dynamic vibration analysis.
Operating Principle
The sensor functions on the principle of electromagnetic induction. The probe generates a high-frequency field at its tip, and changes in proximity to a conductive target modify the eddy-current response. These variations are converted into proportional electrical signals, which the CON031 module linearizes, scales, and translates into standard industrial outputs suitable for machinery protection and control systems.
