Title (EN) MAGNETORESISTIVE SENSOR BASED EDDY CURRENT CRACK FINDER
(FR) DETECTEUR DE FISSURES A COURANT DE FOUCAULT BASE SUR UN CAPTEUR MAGNETORESISTIF
Abstract: front page image
(EN)An apparatus for nondestructive detecting of cracks in lapped electrically conductive upper and lower plates characterized by a probe having a square shape drive coil and a magnetoresistor sensor aligned with the longitudinal axis of the drive coil. The drive coil is intended to extend across the lap joint above the plates with the sensor mounted between the drive coil and plates. A signal generator applies periodic unipolar pulses to the drive coil.
(FR)L'invention concerne un appareil destiné à la détection non destructive de fissures dans des plaques supérieure et inférieure électroconductrices chevauchantes, caractérisé par une sonde présentant une bobine d'excitation de forme carrée et un capteur magnétorésistif aligné avec l'axe longitudinal de la bobine d'excitation. La bobine d'excitation est conçue pour s'étendre dans le joint à recouvrement au-dessus des plaques, le capteur étant monté entre la bobine d'excitation et les plaques. Un générateur de signaux applique des impulsions unipolaires périodiques sur la bobine d'excitation.
