The fourth chapter, temperature detection technology Four The fourth chapter, temperature detection technology 4.1 temperature and detection technology overview 4.2 thermocouple temperature detection technology 4.3 thermal resistance temperature detection technology resistance temperature detection technology The fourth chapter, temperature detection technology Four 4.1 temperature and detection technology overview of temperature and detection technology 4.1.1 the concept of temperature is the physical quantity indicating the temperature of an object. From the point of view of heat balance, the temperature is a sign of internal molecular object random thermal motion intensity: the high temperature of the object, the internal molecular average kinetic energy; low temperature small objects, its internal molecular average kinetic energy. The relationship between physical quantities of the fourth chapter the 4.1.2 temperature detection technology is the 1. scale based on the scale of experience of a certain substance and the change of temperature, which is determined by experimental method and empirical formula is called a scale, experience, Fahrenheit, Celsius, Langmuir, Reaumur etc.. Four (1) the Celsius scale: it is 0 degrees to the freezing point, boiling point positioning water 100 degrees, the distance between two fixed points is divided into 100 equal parts, each one is 1 degrees, denoted as C. The The fourth chapter temperature detection technology (2) Fahrenheit: 1714 German Fall Hite (Fahrenheit) in the 1714 German Fall Hite (Fahrenheit) water with mercury for the medium temperature, made of glass mercury thermometer: according to Fahrenheit, is the freezing point of water is 32 degrees Fahrenheit, the boiling point of 212 degrees Fahrenheit in Fahrenheit, w
