  • Temperature limiter for a glass-ceramic cooking unit
    Patent number: 4633238
    Abstract: A temperature sensor for a temperature limiter is made up of an outer tube and a number of inner component rods. The temperature sensor extends transversely over the top side of a moulding of a heating system for a glass-ceramic cooking unit. The heating system comprises a central heating surface and an outer connectable heating surface disposed in a circle therearound. Disposed in the zone of the central heating surface is an inner component rod whose coefficient of expansion is lower than that of the outer tube, while in the zone of the connectable heating surface the component rods have a higher coefficient of expansion than the outer tube.
