Introduction and usage occasions of common contact temperature sensors
The contact temperature sensor reaches a state of thermal equilibrium through conduction or convection, so that its display value can directly represent the temperature of the measured object. Generally speaking, its measurement accuracy is relatively high. Within a certain temperature, it can even measure the temperature difference inside the object.
However, if the measurement is a moving object, an object with a small heat capacity or a small target, the measurement result will have a relatively large error. The commonly used thermometers include pressure thermometers, resistance thermometers, bimetallic thermometers and liquid-in-glass thermometers, etc. wait. They are widely used in business, agriculture and industry, even in daily life, people often use these thermometers. In the departments of electronics, medicine, metallurgy, national defense engineering and food, the application of cryogenic technology is becoming more and more extensive, and there is also vigorous research on superconducting technology. Now the cryogenic thermometer to measure the temperature below 120K has been well developed. The development of, for example: acoustic thermometer, low temperature thermal thermometer, vapor pressure thermometer and low temperature gas thermometer and so on.
