<p>Device for measuring and/or testing of test objects (1), for example rolled wire, rods, tubes, round billets, etc., with respect to a variable or a combination of variables, for example surface cracks (2), dimensional changes. The device comprises at least one transducer (3), which oscillates backwards and forwards over the surface of the object by means of a motor, the oscillation taking place in the form of a curved path transversely of the longitudinal direction of the object. </p> |
