Device for testing and/or measuring test objects such as rolled wire (1) with respect to quantities, e.g. dimension, form, etc. The invention illustrates how quantity can be calculated via a reverse procedure of distance measurement. By measuring the distance between the surface of the test object, or a part therefor, and reference points (RP), often fictive, pertaining/reference to the eddy current transducer, a quantity such as diameter (D) can be calculated/measured since the distance (A) between e.g. diametrically located reference points or the like is known. By combining the invention with a crack-detecting device, the same transducer arrangement, for instance, can be used to detect both cracks and dimension. |
