Classification and Main Use of the temperature and humidity monitoring device
The temperature and humidity monitoring device is a sensor that can sense temperature and convert it into an output signal. Classification of the device to measure temperature and humidity 1. Contact type The detection part of the contact the temperature and humidity monitoring device has good contact with the measured object, also known as the thermometer. Thermometer achieves thermal equilibrium by conduction or convection, so that the thermometer indication can directly represent the temperature of the object under test. They are widely used in industry, agriculture, commerce and other sectors. These thermometers are also often used in daily life. With the application of cryogenic technology in national defense engineering, space technology, metallurgy, electronics, food, medicine and petrochemical industry, and the research of superconducting technology, cryogenic thermometers for measuring temperatures below 120K have been developed, such as cryogenic gas thermometers, steam pres...
