Abstract (en)
[origin: WO2006082334A1] The invention concerns a method for producing an assembly of at least one transmission coil (B<SUB>1</SUB>) and one reception coil (B<SUB>2</SUB>) for eddy current testing, the reception coil receiving in the absence of fault a complex amplitude signal V<SUB>R</SUB>, subjected to a variation dV<SUB>R</SUB> in the presence of a characteristic fault to be detected. The method consists in selecting the distance ?<SUB>ER</SUB> between the axes of the transmission coil and the reception coil so as to maximize the ratio I dV<SUB>R</SUB>/V<SUB>R </SUB>I.
