Commonly used type of universal bimetallic thermometer is how to use code?

Universal type bimetallic thermometer is one of the bimetallic thermometer, it for its header and heat pipe by a May 180 & deg; Turn the metal hose connection. We all know, bimetallic thermometer is also called the WSS thermometer, so common universal type bimetallic thermometer is how to use the code? We can through the following naming convention to understand this problem. According to this model, named after the logo, we can easily give all sorts of bimetallic thermometer naming. The bimetallic thermometer works by thermal element is composed of two layers of linear expansion coefficient difference relatively large pieces of metal welded together, one end of the element as the fixed end, the other end to free end. When the temperature changes, because the bimetallic strip of material is different, linear expansion coefficient of relatively large differences, and produce different expansion and contraction, leading to the curving deformation of bimetallic strip, equipped with actuator (at the free end Dial pointer and temperature) So that it can directly show the temperature value.
