Capacitor and filling-level signal indicator for filling element of

Abstract

A filling element, used for dispensing non-carbonated or carbonated liquids having a high, a low, or no electrolytic conductivity includes a signal emitter embodied in the form of a cylindrical capacitor having an inner and an outer cylindrical electrode. The filling element is usable for single or multi-chamber counterpressure filling machines having a lower valve housing which is provided with a pressurized gas chamber, and having a filling tube which is held by a contact pin for a filling height signal emitter, which contact pin is longitudinally movable in the valve housing. The signal emitter is essentially formed in that the liquid conveying part of the filling tube is insulated relative to the valve housing, and is embodied as an inner cylindrical electrode which is in contact with the contact pin. The outer cylindrical electrode, which is connected with a further contact pin, is arranged on the outer periphery of the inner cylindrical electrode, and an insulation is interposed between the two electrodes. The upper end of the outer cylindrical electrode extends into the pressurized gas chamber, and the lower end thereof extends beyond the pressurized gas chamber to below the level of the liquid rising in the container which is to be filled to the predetermined filling height.
