Basic knowledge of glass liquid thermometer you must know it!

What is the glass liquid thermometer? In circular transparent glass tube filled with different liquids ( Much as mercury or toluene, ethanol and kerosene, etc. ) , using the liquid thermal expansion, realize the temperature measuring instrument, called a glass thermometer measurement. What are the typical features of glass thermometer? Glass thermometer's main features are: simple structure, direct reading and easy to use, cheap, wide measuring range, etc. , are widely used in daily life, industrial and agricultural production and scientific research in the field of temperature measurement. The structure of glass liquid thermometer and the measurement principle is what? Of glass liquid thermometer is the basic structure of inductive temperature filling liquid thermal bag, glass capillary and scale of three parts. It is composed of the basic conditions of a thermometer. Due to the variety of the thermometer, according to different purposes, its structure is not entirely the same, if some have safety glass capillary thermometer bubble, bubble, etc. Liquid thermometer measurement principle is: glass thermometer is a kind of thermometer, it is made according to the substance of the principle of heat bilges cold shrink. When thermal bubble surrounding temperature changes, temperature of the liquid volume is changing, the liquid column within the capillary rise and fall, then through the scale reads different temperature values, in order to achieve the purpose of measuring temperature.
