Basic knowledge of the belt far eastone bimetallic thermometer

Take far eastone bimetallic thermometer and bimetallic thermometer is very similar, you can distinguish between far eastone bimetallic thermometer and bimetallic thermometer? In order to facilitate everyone to distinguish, the following to introduce everyone to take away the basic knowledge of the bimetallic thermometer. With remote transmission of bimetallic thermometer temperature sensing element is a bimetallic strip. Take far eastone bimetallic thermometer bimetallic strip is the difference of expansion coefficient is larger of the two kinds of metal welded together double metal plates, fixed at one end, for a period of freedom. When the temperature rises, the big pieces of metal elongation of expansion coefficient, and the bimetallic strip bending to the side of the small pieces of metal expansion coefficient. The higher the temperature, the bigger the degree of bending. That is to say, with far eastone bimetallic thermometer bimetallic strip bending degree have corresponding relationship with temperature, which can be used to indicate that the bending degree of bimetallic strip temperature. Typically, small expansion coefficient in the bimetallic strip layer called the passive layer, called big expansion coefficient of a layer of active layer. With remote transmission of bimetallic thermometer calibration project ( 1) A visual inspection; （ 2) Value for verification; （ 3) Pointer balance; （ 4) Return error; （ 5) Repeatability; （ 6) Value for stability.
