Do you know the electric contact bimetallic thermometer electric contact role?

A lot of people know, in instruments and meters, electric contact bimetallic thermometer is more and more get the welcome of people, because it has many kinds of structure form, can satisfy the different demands of people, but the electric contact bimetallic thermometer electric contact what role? To introduce the following specific, electric contact bimetallic thermometer, divided into double upper and lower limit and lower limit, the shifter lever is adjusting the position of the temperature ( Such as dial rod in 60 degrees) , when the temperature more than 60, the shifter lever and the pointer will contact, then alarm effect. Bimetallic thermometer temperature sensing element is composed of two layers of different linear expansion coefficient of metal stitch welding together, made the big pieces of metal linear expansion coefficient is called the active layer, the other one is called passive layer, one end of the element is fixed, the other end of the free end, when the measured temperature changes, as a result of the two layers of metal linear expansion coefficient is different, the free end by the combination of torque and bending ( Or deformation) , the change of curvature and physical properties of the bimetallic strip material, length, the thickness of each layer, temperature, and has nothing to do with the width. When temperature is designed, the bimetallic strip of material and geometry size, so the change of curvature is only related to temperature, if on the free end is equipped with drive mechanism, pointer and dial indication in temperature, so you can directly show the temperature value. People often use electric contact bimetallic thermometer can know, electric contact bimetallic thermometer with live display temperature, intuitive and convenient; With functions of automatic cut off power and alarm; Safe and reliable, long life and other characteristics, so, in industrial production, electric contact bimetallic thermometer will be more and more get the welcome of people.
