WSS bimetallic thermometer temperature measuring principle is what?

WSS bimetallic thermometer is also called the bimetallic thermometer, the temperature measurement principle is to round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. Below to introduce a universal type of bimetallic thermometer.
