According to the direction of connection for bimetallic thermometer are classified

The principle of the bimetallic thermometer is based on solid heat expansion principle, bimetallic thermometer is a kind of measurement in the field of low temperature measuring instrument, measuring temperature is usually put the two pieces of expansion coefficient difference is relatively large pieces of metal stitch welding together, constitute a bimetallic temperature sensing element. When the temperature changes, because the bimetallic strip of the materials of the two different linear expansion coefficient is relatively large, produce different expansion and contraction, leading to the curving deformation of bimetallic strip. As there are different according to different deformation amount of momentum transfer, the amount of rotation drive connection shaft, shaft drive at the other end of the indicating needle, when bimetallic strip feel the temperature change, Pointers can be on a circular dividing scale to indicate the temperature.

common bimetallic thermometer: according to the bimetallic thermometer pointer to the connection with the protection tube direction bimetallic thermometer can be divided into axial, radial and 135 ° to the model and universal model. 1. Axial type bimetallic thermometer: pointer vertical connection tube plate and protection. 2. Radial type bimetallic thermometer: pointer GuanPing line connection plate and protection. 3. Type 135 ° to the bimetallic thermometer: pointer plate connected to protection tube into 135 °. 4. Universal type bimetallic thermometer: pointer plate connected to the protecting tube Angle can be arbitrary adjustment. Hangzhou bimetallic thermometer manufacturers instrument co. , LTD. Is a bimetallic thermometer manufacturers, professional production of bimetal thermometer, brought a lot of industry test is convenient, can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature.
