Abstract
A measuring device for contactless determination of condition of screw shaped structural elements comprises two oppositely located coils supplied with an alternating current spaced from one another so that an electrically conductive structural element passes therebetween, and transporting elements formed so that the structural element is guided on an edge so that a distance between the structural element and at least one of the coils remains constant during a measuring process.
