Abstract

L'invention est relative à un procédé de réalisation d'un ensemble d'au moins une bobine d'émission (B1) et une bobine de réception (B2) pour contrôle à courants de Foucault, la bobine de réception recevant en l'absence de défaut un signal d'amplitude complexe VR, soumise à une variation deltaVR en présence d'un défaut type à détecter.On choisit la distance DeltaER entre les axes des bobines d'émission et de réception de manière à maximiser le rapport |deltaVR/VR|.
