Arrangement for the contactless detection or the contactless measurement of mechanical stress states of machine parts

摘要

A layer of amorphous, magnetostrictive material is arranged on the machine part, for example a shaft (1). This layer (2) changes its magnetic permeability under the influence of mechanical stresses, so that, in turn, there is a change in the inductance of a sensor (3) arranged in the vicinity of the machine part (1).
