Copper nickel plated glass rod thermometer casing

Glass rod thermometer working principle: using thermal bubble in a transparent glass and heat within the capillary liquid varies with temperature measured medium heat bilges cold shrink to measure the effect of temperature. Industrial liquid thermometer with a glass rod according to the thermal bubble and thermal fluid column assumes the Angle can be divided into straight and Angle thermometer; According to the structure can be divided into rod thermometer and internal standard thermometer. Common glass rod thermometer for straight rod thermometer. Due to the glass rod thermometer is made of glass, brittle faults, in the process of industrial use, often can add casing outside thermometer. Glass rod thermometer casing material for copper plating nickel material commonly, the length of the six & throughout; ，8” ，10” ，12” ，16” And so on. Set of outside the root glass rod, glass rod thermometer wrap up, resist the measured medium pressure, corrosion and protection, make the thermometer can work normally.
