Bimetallic thermometer dial diameter is introduced

Dial bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Dial bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Bimetallic thermometer is applied in chemical and petrochemical industry; Power engineering; Field of food. Construction machinery and general factory. Instrument bimetallic thermometer dial to share with you today introduced the commonly used bimetallic thermometer dial diameters are: 50 mm and 63 mm, 80 mm, 100 mm, 125 mm and 150 mm optional, have special dial can be customized, dial according to the actual size order to select the site using the environment and requirements. Dial temperature range: ‐ 80 ~ 550 c is optional. Table card calibration: ℃ and scale ℉ optional. Principle structure of bimetallic thermometer is round shape into threaded heat bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial.
