Knowledge is introduced about the bimetallic thermometer

Bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Can be directly measured in the process of various production - 80℃- Liquid + 500 ℃ range steam and gas medium temperature. Bimetallic thermometer is mainly used in industry of element is one with two or more pieces of metal laminate composed of multilayer metal together, using two different metal working in the principle of expansion degree of different temperature changes. 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. Speaking of bimetallic thermometer, the related knowledge about several aspects: 1. Bimetallic thermometer in custody, use and maintenance in the process of installation, use and transportation, should try to avoid collision protection tube, don't make the protection tube bending, deformation. When installation, it is forbidden to twist the instrument shell. The temperature of the instrument often work best to 1/2 to 3/4 in scale range. 2. Use guidelines in order to ensure accurate temperature measurement, insertion depth of the heat pipe must be greater than the length of the temperature sensing element. Thermometer in the case of normal use shall be regular inspection. Is every six months.
