Abstract
An assembly, especially for a beverage-vending machine with a container for the storing, cooling and carbonating of water including two measuring electrodes arranged in the container at differing horizontal and vertical distances from an electrically conductive inner wall of the container connected to ground, one of these in the area of the ice layer under formation. The measuring electrodes obtain resistance values for the ice and/or water that arise between the electrode and the inner wall of the container. In order to cool the water independently from its physical-chemical composition, potentials corresponding to the resistances are derived and are supplied to a differential amplifier. Depending on a size comparison of the two resistance values, a cooling apparatus that affects the contents of the container is switched on or off.
