Do you know how to named WSS bimetallic temperature is?

WSS bimetallic thermometer, with its high precision, long service life, get the favour of to many industrial equipment manufacturers. Its working principle is its working principle is to put 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 you know how WSS bimetallic thermometer is named after? Today we talk about the naming WSS bimetallic thermometer. Finish see this picture, is clear?
