An inductive method for monitoring impurities in non-ferromagnetic metals

Abstract

The paper presents a method for electromagnetic measurements of the chemical impurities’ con-centration in samples of non-ferrous metals. The principle of measurements is described and the in-fluence of the inaccuracy in geometric dimensions of the analyzed metal volume on the measure-ment error is established. The proposed measurement method was tested on model samples of a tin-lead alloy with an admixture of copper particles of various mass concentrations. For the select-ed combination of the analyzed metal and impurities a calibration curve of the sensor was ob-tained in the concentration range from 0 to 10%.
