PROVHUVUD FOR INDUKTIV YTPROVNING AV METALLISKA ARBETSSTYCKEN |
摘要 |
A test head for the inductive surface testing of metallic workpieces is provided with eddy-current probes respectively disposed in a plurality of holes in a holder. Each eddy-current probe is part of an individual resonant circuit and formed of coil with a ferrite core, the axis of the coil extending substantially at right angles to the workpiece surface. The holder comprises an electrically or magnetically conductive material, thereby increasing the area over which the field of each said probe is effective. |
