Different lengths of bimetallic thermometer

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. Different lengths of bimetallic thermometer is bimetallic thermometer heat pipe length, SS304 material heat pipe welding in the sump leakage protection, thermal tube length according to the custom. General common bimetallic thermometer heat pipe length is: 50 - 2000 mm is optional. Different lengths of bimetallic thermometer is suitable for different pipe and industrial production, machinery manufacturing, etc. 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.
