发明名称 Electromagnetic-acoustic transducer and ultrasonic test system having the same
摘要 An electromagnetic-acoustic transducer for ultrasonic testing of test objects which are composed substantially of an electrically conductive material includes a magnet system that produces a magnetic field intended to penetrate into the test object, and an inductive coil arrangement that produces an electromagnetic alternating field superimposed on this magnetic field in the test object, and that detects electromagnetic alternating fields emitted from the test object, wherein magnet system is arranged in a magnetization unit, the coil arrangement is arranged in a probe unit separate from the magnetization unit, the probe unit is mounted such that it can move relative to the magnetization unit in the area of the magnetic field.
