A New Method of Eddy Current Impedance-Extracting and Hardness-Classifying for Valves

This paper describes a new method of eddy current impedance extraction and hardness classification for valves, which is used in online classification. A finite element simulation is conducted to estimate the base magnetic response in specimens with various initial permeabilities, and a scatter diagr...
