Temperature society, you should know some knowledge!

Humans would have the temperature different feeling of nature: summer heat and winter cold; Hot fire, ice freezing & hellip; … However, when people tell about temperature does not have a standard. But at the time, the doctor can only touch the patient, with feeling to speculate about temperature of the body. This method obviously prone to error, is not accurate. With the development and the progress of the society, people increasingly need a measuring temperature & other; A ruler & throughout; 。 According to plan, during the warring states period, our people will know that the water in the bottle, by observing the water freezes whether to estimate the degree of drop in temperature; In the early han dynasty, had to ice temperature measuring method, namely, by observing the state of ice, to know the temperature. Invention of thermometer, however, is the Italian scientist Galileo. Galileo was born on February 15, 1564 in Pisa, Italy. He showed a strong desire for knowledge at an early age. Objects in nature, the stars in the sky, the sun, can arouse his curiosity greatly, so, just had such an achievement! As science and technology developed today, we should be more as time progress! Now is the rapid development of industrial society, we should know some industrial 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. Industrial bimetallic thermometer is widely used in petroleum, chemical, metallurgical, textile, food and other industries. The scene display temperature, intuitive and convenient safe and reliable, long life; Core-pulling thermometer can not stop short time machine maintenance or replacement. The axial, radial and 135 & ordm; Type, universal type, such as complete varieties, suitable for all kinds of the needs of the installation. So, according to need, you can customize various types of thermometer. Industrial bimetallic thermometer still has a lot of kinds, and with the need to constantly produce new thermometer of the society, should choose to suit his needs when using a thermometer.
