Abstract

A device for measuring a wear condition on the plain bearing surface of a sensor plate comprises a measuring apparatus, which has wear sensors of a sensor plate integrated into the plain bearing surface. To capture the material removal at the plain bearing surface due to wear an evaluation apparatus is in signal connection with the wear sensors. The evaluation apparatus is designed, with respect to programming, in such a way that a change, in particular an increase, in the ohmic resistance value of the electrical conductor of a certain wear sensor can be captured in dependence on its own material removal, in order to thereby ensure that the amount of the material removal at the plain bearing surface and/or the remaining thickness of the plain bearing surface at the location of said certain wear sensor can be inferred from the detected change in the resistance value.
