Bimetallic thermometer diameter as small as possible?

Bimetallic thermometer is applied in chemical and petrochemical industry; Power engineering; Field of food. Construction machinery and general factory. Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Bimetallic thermometer can be directly measured in the process of various production - 80 ℃ ~ + 500 ℃ within the scope of liquid, steam and gas medium temperature. Those metal thermometer diameter as small as possible? Instrument to solve for you: no, she isn't. Bimetallic thermometer pipe diameter is according to use demand to decide, not as small as possible, in order to meet the characteristics of different devices, the diameter of the heat pipe are commonly used: phi is 6 mm, 6. 35 mm, 8 mm and 10 mm, 12 mm, SS304 material heat pipe heat pipe welding in the sump leakage protection, heat pipe length and diameter can customize according to the customer. Bimetallic thermometer is a 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.
