ABSTRACT:
A device for simulating a moving test object sensing transducer uses a plurality of individual transducers which are stationary relative to each other (for example eddy-current based surface transducers), and a selector unit. The individual transducers are, for example, mounted in a plane parallel to the surface of the test object to be sensed and scan the test object with respect to a characteristic, for example a crack. The resultant simulated transducer signal is signal processed by means of, for example, automatic compensation and vector transformation techniques. By automatically switching in the individual transducers in succession, for example in a continuously recurrent sequence, signals originating from different individual transducers completely or partially determine different time portions of a resultant signal, and a quantity or combination of quantities is tested and/or measured by means of the transducers which in turn can be identified as deriving from different physical regions of the surface being tested.
