Arrangement for characterizing the level of an electrically conductive material in a container

The invention relates to an arrangement for characterizing the level of an electrically conductive material in a container comprising a side of the container inner space arranged sensor element with an excitation coil and two gradiometrisch interconnected receiver coils, the arrangement for applying the exciting coil with an alternating current, for detecting the on the gradiometrisch interconnected receiver coils resulting output voltage is formed based thereon for determining the proportion of the output voltage with no phase shift to the alternate current and / or the proportion of the output voltage with a phase shift of 90 ° with the alternating current, and for characterizing the filling level.
