Eddy current inspection apparatus and probe. |
| 摘要 |
<p>©7 An eddy current inspection probe includes a bobbin (22) housing a central ferrite rod (24). Two coils (26, 28) are wound around one end of the ferrite rod (24). The coils (26, 28) 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.</p> |
