DEVICE AND METHOD FOR NON-DESTRUCTIVE AND CONTACTLESS DETECTION OF DEFECTS IN A TESTPIECE

摘要

The device has a stationary measuring unit (16) for carrying an eddy current measurement or a magnetic leakage flux measurement at a relative test item (10). A monitoring unit (20) has three spacer sensors (22) arranged in circumferential direction around test item. An independent claim is also included for a method for damage- and contact free recording of errors in a test item.
