Intelligent Coating Thickness Gauge

【Unraveling Thickness Measurement: Principles and Classification of Key Tools​】 Thickness measurement plays a significant role in industrial quality control, and dry film thickness gauge, thickness tester and coating thickness measurement are important components of thickness measurement. For cured coatings, a dry film thickness gauge is chosen, while for a wider range of materials, a thickness tester is selected. Both are used to meet the requirements of coating thickness measurement. Technically, of magnetic induction and eddy current. For instance, coating thickness measurement in car painting, magnetic induction acts on the magnetic substrate: a dry film thickness gauge uses it to emit a magnetic field, and the coating thickness measurement changes the flux. For instance, in the measurement of coating thickness in aerospace, the eddy current principle is applicable to non-magnetic metals: the thickness tester generates eddy currents, and the presence of the coating causes it to…
