摘要
A sensor head with multiple sensors for ACFM based crack detection and sizing. An alternating current electromagnetic yoke is used to induce a uniform magnetic field on the surface of the test piece. A reference coil in the sensor head detects the background field strength of the magnetic field. Multiple sensors, the axis of each of which is in an angled relationship to the reference coil, detect variations in the magnetic field. The sensor coil axes can be chosen to detect and size both angled and straight cracks.
