Bimetallic thermometer shell have a requirement

Bimetallic thermometer shell have a requirement? Instrument to answer for you today. Because of the 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. So shell for bimetallic thermometer is a requirement, for the best is full of SS304 stainless steel material, because SS304 material corrosion resistance, high temperature resistance, never rust, never break, use full of SS304 stainless steel material can ensure the bimetallic thermometer use safe and reliable, long service life. 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.
