How to make a standard of bimetallic thermometer?

Bimetallic thermometer is more and more widely, the scope of application of demand market is becoming more and more big, but many customers are experts from yes in his field, but for bimetallic thermometer is not so understand. Today we come to share, how to make a standard of the bimetallic thermometer. Before making bimetal thermometer thermometer, we must first understand the working principle of bimetallic thermometer and its composition. 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. And a standard of the structure of the bimetallic thermometer mainly by cover, table, table card, pointer, temperature sensing element, the teeth, heat pipe. Know the above parameters, we can produce standard bimetallic thermometer.
