Bimetallic thermometer working principle diagram

Bimetallic thermometer is indispensable in our life and work. Bimetallic thermometer working 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. A bimetallic thermometer principle diagram ( Induction flat shape figure) : the bimetallic thermometer sensors have linear spiral and plane spiral. Bimetallic thermometer principle diagram 2: ( Heating principle diagram) Three: (bimetallic thermometer principle diagram Working principle diagram) Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature.
