<p>A circuit arrangement has a field producing electrode device which is connected in an LC network and exposed to a spatial area of the field such that the capacity of the capacitor system with the electrode device alters according to dielectric properties of material present in the spatial area, an insulating layer extending on a rear side of the field electrode device which is oriented away from the spatial area, a screening electrode device which extends on the rear side of the insulating layer which is oriented away from the field electrode device and a field extinction electrode device which has an electrode surface which is oriented towards an extinction area. The field expansion electrode device and the field extinction electrode device are arranged such and impinged upon by a voltage that the spatial area of the field and the extinction area are superimposed on each other in sections.</p> |
