In accordance to the proposed block-schemes, electric principle circuits as well as developed algorithms a specialized device prototype for non-destructive control by means vibration diagnostic is created. The proposed vector approach allows usage of invariant quantities which characterize the state of an observed object. The usage of such quantities makes it possible to investigate the spatial properties of vibrations and thus increase the efficiency of the diagnosis. On the basis of the analysis of the vibrations of centrifuge bearing using the methods of the vectorial PCRP the local defect,which has an impact character, is detected and described.
