Abstract:
1. A device for non-destructive testing of an electrically conductive part comprising: an induction portion; a receiving portion; and processing means; wherein the induction portion comprises an inductor dissociated into n elementary inductors of layer type supplied at different frequencies f wherein the receiving portion comprises n′ magnetic receivers distributed over m columns, each column comprising at most n receivers, the magnetic receivers being connected to one another over each column, the m columns of receivers being supplied by electrical signals v wherein the processing means comprises, for each column of receivers of row i with 1≦i≦m, means of measuring the signal at terminals of this column of receivers followed by means of demodulating this signal at the frequencies f wherein the magnetic receivers are directed according to an axis of sensitivity, a main direction of currents of these elementary receivers being directed according to a perpendicular axis.
