FIELD: flaw detection by magnetic means. SUBSTANCE: device has flexible substrate with at least one or array of eddy-current transducers; substrate is, essentially, flexible film or rectangular net; transducers are mounted on substrate for displacement over it or fixed on substrate for retaining orientation of normal axis to perpendicular to substrate surface at point of location of transducer. Computer 1 can determine position coordinates of respective inspection point by sequence of time steps and process, together with check signal, image in covering plane. EFFECT: improved accuracy. 8 cl, 11 dwg
