A method of path measurement uses eddy current principles and a sensor which interacts with a measuring object. The sensor has an electrical connector and a sensor coil. In accordance with the method, an operating voltage is applied to the sensor such that a magnetic field is built up by an oscillator in cooperation with the sensor coil. A measuring object may be moved in the vicinity of the sensor coil through an opening in the sensor coil to produce field strength changes adjacent to the coil and the oscillator. The field strength changes are detected by an evaluation circuit and transmitted to a microcontroller. The microcontroller processes the signals of the evaluation circuit and provides the evaluation circuit with said signals via an output and protection circuit. The sensor coil consists of a plurality of windings constructed in a planar manner.
