ABSTRACT:
An arrangement for measuring the distance between a metallic workpiece and a processing tool includes, in addition to a sensing device having a reactance, a compensation sensing arrangement having a reactance with one of the reactances being inductive and the other capacitive and with the reactances being dimensioned and connected in opposition in such a way that by a predetermined lateral approach of the workpiece to the electrodes the tool can be compensated by changes in the reactances.
