Способ относится к неразрушающему контролю и может найти применение при контроле толщины гальванических покрытий, в частности при измерении толщины немагнитных электропроводных покрытий ферромагнитных изделий. Изобретение повышает точность контроля и расширяет функциональные возможности. Для этого преобразователь питают напряжением низкой и высокой частот, на низкой частоте индукционным методом измеряют расстояние между преобразователем и основой изделия (расстояние A), на высокой частоте вихретоковым методом измеряют расстояние между наружной поверхностью покрытия и преобразователем (расстояние B), а о толщине покрытия судят по разности этих расстояний.The method relates to non-destructive testing and can be used when controlling the thickness of electroplated coatings, in particular when measuring the thickness of non-magnetic electrically conductive coatings of ferromagnetic products. The invention improves the accuracy of control and extends the functionality. To do this, the converter is supplied with low and high frequency voltages, at a low frequency the distance between the transducer and the product base is measured by an induction method (distance A), the distance between the outer surface of the coating and the transducer is measured at a high frequency, and the thickness of the coating is measured by the difference of these distances.
