How do temperature sensors work in automatic cookers?
A temperature sensor, as found in autommatic cookers, toasters, and coffee makers, etc. is simply a switch which cuts the power when a given temperature is achieved. A common switch is one constructed of two dissimilar metal such as copper and nickel. When bonded together and heated, the different linear expansion rates of the two metals causes the bimetal switch to bend, thus breaking the electrical contact in the appliance. When the temperature begins to drop, the bimetal switch begins to straighten out and thus closes the switch re-establishing electrical contact. This sequence is repeated constantly while the appliance is in use.
