Example Embodiment

[0023] The following further description with reference to the drawings does not limit the scope of the present invention.

[0024] See Figure 1 to Figure 6 As shown, the present invention includes a metal cylindrical conductor 1 and a saddle-shaped probe 5. The saddle-shaped probe 5 includes a housing 6, a signal wire 4 and an excitation coil 3. The housing 6 is arc-shaped and is located at the bottom of the housing 6. Two base chucks 7 are respectively provided on both sides. The base chucks 7 are used to fix the saddle-shaped probe 5, and a detection coil 2 is provided on the upper part of the two base chucks 7. There are two detection coils 2 connected in series therebetween. There are four detection coils 2 in total. Two excitation coils 3 are provided on the upper part of the detection coil, and a signal line 4 is provided between the two excitation coils 3. . The saddle-shaped probe 5 has an arc shape. The number of the saddle-shaped probes 5 is four, which are arrange...

Abstract

The invention relates to a novel eddy-current sensor probe which comprises a metal cylindrical conductor and a saddle-shaped probe. The saddle-shaped probe comprises a square shell, a signal line and excitation coils. Two base chucks are disposed on two sides of the bottom of the shell respectively. A detecting coil is disposed on the upper portion of each base chuck. Two detecting coils which are in series connection are disposed between the detecting coils on the upper portions of the base chucks. Two excitation coils are disposed on the upper portions of the detecting coils. The signal line is disposed between the two excitation coils. The novel eddy-current sensor probe is advanced in circuit design and manufacturing process, reliable in performance and stable in operation, and can detect broken strands of non-ferromagnetic aluminum stranded conductors well.
