IPC: G01N27/90
Filed: 1987-03-20
Abstract: PURPOSE:To enable the attainment of reliable inspection by constructing the probe of an eddy-current flaw detector of two sets of coils each of which is composed by combining four 1/4 circuit coils. CONSTITUTION:The probe of this eddy-current flaw detector is constructed of two coils 4A and 4B which are composed by combining 1/4 circular coils P1-P4 and Q1-Q4 arranged on planes P and Q respectively. In each these coils 4A and 4B four 1/4 coils are so arranged that they form one circle. The coil 4A is composed by connecting the coils P1-Q2-P3-Q4 in series and the coil 4B by connecting the coils Q1-P2-Q3-P4 in series. Each of the coils 4A dn 4B forms one circle when the respective 1/4 circular coils are projected onto a plane parallel to the plane P or Q. Since the probe of the eddy-current flaw detector is constructed of two coils disposed on the planes P and Q being perpendicular substantially to the axis of a tube 1, in this way, the effect of a tube plate or the like is removed and reliable inspection can be executed by using a differential amplifier, even when a tube end part wherein the tube 1 is expanded is inspected.
