Bimetallic thermometer can do refrigerator thermometer?

Bimetallic thermometer is a frequently used in industrial equipment the thermometer on the table, its working principle is to put the two pieces of expansion coefficient difference is very big pieces of metal welded together. When the temperature changes, the difference is very big, caused the different expansion coefficient of expansion and contraction, the deformation of sheet metal bending. According to different deformation and produce different momentum, momentum to drive the connection shaft and the other end of the indicating needle, indicate the temperature. So, refrigerator thermometer bimetallic thermometer can do? Refrigerator thermometer has a lot of kinds, we can say today working principle of the use of bimetallic thermometer is made of refrigerator thermometer.
