An inductive measurement is carried out of the distance between a workpiece ( ) and a working head ( ), which bears an induction coil ( ), through which an alternating current flows and which is part of a resonance circuit whose oscillation frequency is monitored for changes which occur as a consequence of changes in the distance between the workpiece ( ) and working head ( ). In this case, the working head ( ) acts on the workpiece ( ) with a material ( ) having a dielectric constant greater than 1. The frequency of the alternating current is in the megahertz region or just therebelow. Last but not least, the induction coil is screened from external electric fields in order to avoid the influence of parasitic capacitances.
