WSS in the bimetallic thermometer WSS what do you mean?

WSS bimetallic thermometer, bimetallic thermometer is we used to say, it is a common used to measure the - 50 to 500 c temperature instrument, widely used in petroleum chemical industry, industrial equipment, hvac, nuclear power, and Marine and other fields. 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 a transmission mechanism on the free end pointer and dial temperature labeling) So that it can directly show the temperature value. Then you know WSS represent what meaning be? Actually W represents temperature instrument, metal expansion type S representative, after a representative S thermal bimetal element. After buying the bimetallic thermometer should pay attention to timely cleaning and inspection, and testing its accuracy on a regular basis.
