Do you know how a bimetallic thermometer is made?

As is known to all, the working principle of bimetallic thermometer is the 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 the use of the bimetallic thermometer is very broad, so you know how a bimetallic thermometer is made? Today we have in our T300C, for example, to explain to you a pair of metal thermometer production process? Structure: the axial type cover circle: flange type, full stainless steel material: stainless steel SS304 tooth head: 1/2 & quot; NPT other optional surface diameter: 80 mm heat pipe diameter: 6. 35 mm heat pipe length: 150 mm ( 50 - Optional) around 2000 mm. Temperature range: 0 - 150° C ( Can be customized) Accuracy: & plusmn; 1. Table: 5% glass protection grade: IP65 ( Dust, water) With the above parts, we can produce a bimetallic thermometer. Temperature adjustment and trial and leak in the production process is a very important link, also should especially take note.
