EDDY CURRENT SENSOR AND TUBE TESTING TOOL HAVING AT LEAST ONE SUCH SENSOR |
摘要 |
For the nondestructive testing of an electrically conductive part (T), an eddy current sensor (22a) is proposed comprising two transmitter windings (26) and one receiver winding (28). These three windings are arranged symmetrically with respect to a reference plane (P1) oriented perpendicular to the surface of the part (T). The receiver winding (28) is placed between the active portions (26a) of the emitter windings (26) and perpendicular to the plane (P1), whereas the transmitter windings (26) are substantially parallel to said plane. The coils and connections of the transmitter windings are such that the receiver winding is not traversed by any current in the absence of a fault. A tool for testing a tube (T), such as a steam generator tube, has two sensors oriented at right angles to one another.
