Abstract

PURPOSE: To prevent errors from occurring due to the relative position relationship between the coil and the flaw by arranging three coils in the same form and the electric characteristics so that the central points of the coils are positioned at the respective apexes of a false triangle.
CONSTITUTION: The other ends of the coils 31W33 are grounded through the resistance 5 with the common connection while the detection signal S is extracted at the connection point of these coils and the resistance. Otherwise, the other ends of the coils 31W33 are grounded with a common connection while the detection signal S is extracted from another coil 4 provided surrounding the coils 31W33. In this manner, the three coils 31W33 in the same form and the electric characteristics are so arranged that the central points of the coils 31W33 are positioned at the respective apexes of a false triangle T. As a result, since the three coils undergo the same condition simultaneously, any flow can be detected even if caused in any form.
