What are the typical features of common universal type of bimetallic thermometer?

Universal type bimetallic thermometer is a member of the bimetallic thermometer, it is the working principle of thermal element is composed of two layers of linear expansion coefficient difference is relatively large pieces of metal welded together, one end of the element as the fixed end, on the other side of the 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. So what are the typical features of common universal type bimetallic thermometer? Common universal type is the main characteristic of the bimetallic thermometer meter and the connection mode of the heat pipe, they are via a can 180 & deg; Rotating metal hose connection, this connection mode will allow universal type bimetallic thermometer meter can be 180 & deg; Rotation, this also is & other; Universal type bimetallic thermometer & throughout; The name of reason.
