MAGNETORESISTIVE SENSOR BASED EDDY CURRENT CRACK FINDER
摘要
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.
