Based on the principle, a Steel material sorting instrument was made to detect the steel permeability level, through the permeability level, combined with the central processing circuit steel hardness values reflect iron parts, materials and the carbon content of steel, mixing nondestructive sorting.
In the production process, the iron and steel materials and components of the mixture have occurred from time to time.
If only the metal material is different, the other parameters are fixed, changes of the coil impedance will be only related to metal materials.
