Abstract
The invention concerns a method for producing an assembly of at least one transmission coil (B1) and one reception coil (B2) for eddy current testing, the reception coil receiving in the absence of fault a complex amplitude signal VR, subject to a variation δVR in the presence of a characteristic fault to be detected. The method consists in selecting the distance ΔER between the axes of the transmission coil and the reception coil so as to maximize the ratio IδVR/VRI.
