Bimetallic thermometer of axial and radial direction is how to return a responsibility?

Speaking of bimetallic thermometer, we all know that it works on the basis of the principle of the expansion of the solids, the two pieces of expansion coefficient difference is very big pieces of metal welded together. When the temperature changes, the difference is very big, caused the different expansion coefficient of expansion and contraction, the deformation of sheet metal bending. According to different deformation and produce different momentum, momentum to drive the connection shaft and the other end of the indicating needle, indicate the temperature. So the axial and radial bimetallic thermometer is how to return a responsibility? Radial and axial actually refers to the bimetallic thermometer is the header and the connection mode of the heat pipe. If the header and the heat pipe is horizontally, we call this kind of connection thermometer radial type bimetal thermometer; If header and heat pipe into vertical, we call this kind of connection thermometer type axial bimetallic thermometer. Two different connection just in order to meet the needs of different installation environment.
