Embodiments of the present invention provide a measuring device with a receiver coil array and evaluator. The receiver coil array is configured to detect three magnetic field components of a magnetic field of a conductor loop array generated by an electric alternating current signal and to provide a magnetic field component signal for each of the detected three magnetic field components. The evaluator is configured to evaluate the magnetic field component signals in order to determine the phase relation to the electric alternating current signal allocated for the magnetic field component signals, wherein the phase relations each include coarse position information of the conductor loop array relative to the conductor loop array and wherein the evaluator is configured to determine a resulting intersection of the coarse position information, wherein the resulting intersection includes or results in fine position information of the receiver coil array relative to the conductor loop array.
