Zusammenfassung:	A capacitive sensor device configured for being connected to at least one electric heating member serving as a capacitive antenna electrode. The capacitive sensor device includes a common mode choke connected between the heating current supply and the electric heating member, a capacitive sensing circuit configured to determine a complex electrical impedance between the electric heating member and a counter electrode, an electric measuring shunt for providing a voltage that is representative of an electric current flowing through the electric heating member, and a remotely controllable source of direct current electrically connected in parallel to the heating current supply. The remotely controllable source of direct current is configured to provide, upon receiving a remote control signal, an electric pulse having a predetermined amount of electric charge to the at least one electric heating member.
