Eddy current testing apparatus including a two coil probe having sandwiched windings |
| 摘要 |
An eddy current inspection probe includes a bobbin housing a central ferrite rod. Two coils are wound around one end of the ferrite rod. The coils form two legs of a bridge circuit driven at 1.5 to 2.0 MHz. Defects are located by detecting phase shift in the bridge output.
