The flexible chains align themselves optimally to the surfaces of all relevant object diameters. The arrangement of the probes in circumferential direction also provides extremely short untested end zones and guarantees overlapping of the identical probes. Overlap is achieved at low speed and also at full motion speed in axial direction of the component. The ultrasound is coupled by means of a water gap between probe and object surface. A motorized gap adjustment allows for convenient operation of the testing system with respect to gap optimization according to different surface curvatures or object diameters.
