Testing device for ferromagnetic tubes and/or rods

摘要

In a testing device for ferromagnetic tubes and/or rods having one or more direct current magnetic field magnetic yokes, through whose pole shoe regions the tubes/rods are transported along their longitudinal axis, and having one or more testing probes in the region of the tube surface/rod surface, it is proposed to arrange the testing probes in such a way that they are passed by a specimen section before and/or after the magnetic yoke. By this means, the rotation of the yoke or the specimen is dispensed with. <IMAGE>
