ABSTRACT:
A device for sensing the number of items (14) consecutively disposed in a compartment (12), preferable bottles or cans disposed in a beverage magazine (13) in a refrigerator (10). At each item (14) at opposite sides of said item electric conducting areas (20a,b,c;21a,b,c) are provided which form a capacitor (22a,b,c). The capacitors formed in each compartment are interconnected to form a circuit (C.sub.k) the capacitance of which depends on the number of items (14) in the compartment (12).
