FIELD: measuring equipment.
SUBSTANCE: invention can be used for nondestructive testing of pipes. Essence of the invention lies in the fact that the eddy current flaw detector measuring circuit for the pipes inspection contains the eddy current converter and the generator connected to the flaw detector signal processing and control unit, generator is connected to the first converter coil, phase shifter – to the second one, adjacent to which the non-magnetic current-conducting ring is coaxially located, and the converter is connected by one measuring channel to the signal processing and control unit.
EFFECT: possibility of simplifying the circuit diagram.
