The prospects and state-of-the art related the development of automated non-destructive testing systems are considered. The formation of the tendency concerned with creation of the adaptive automated systems for complex testing based on the application of various physical principles to obtain a synergistic effect is indicated. The factors affecting the variability of eddy current probe signals during the manual and automated eddy current testing were analyzed. The advantages of selective probes of double differential type for automated systems development are indicated. Features of the design and characteristics of multichannel automated systems based on the eddy current method application developed in Ukraine are presented, in particular: a robotic eddy current testing system for detection and identifying of in-service defects in the tubes of secondary reforming furnaces; the eddy current unit of the multi-channel system of complex testing of railway axles during their production; automated system of complex testing of wheel pairs in the conditions of repair plants; eddy current block of the system for complex inspection of railway rails during their production. 30 Ref., 1 Tabl., 12 Fig.
Keywords: automated system, complex non-destructive testing, eddy current defectoscopy, eddy current probe of double differential type
