Bimetallic strip in thermostat stops too fast

WebThe difference in the coefficients of expansion of two metals explains that the bimetallic strip curves on the side where the coefficient of expansion is the smallest. This property is exploited in many devices like the thermosensitive switch (see animation fire alarm ). This twisting is all the more important as the bimetallic strip is long. WebAug 10, 2015 · heat. Assuming the ambient temperature doesn't change, the bimetal strip now drops in temperature to again something less than the hysteresis. It sits there forever, or until the device temperature drops the remaining difference. The bimetal strip then trips, opens the contacts, and the cycle repeats. Looks like it needs more than just a resistor:
