NTC thermistors are sensitive to air flow when they are in self-thermal status, so NTC thermistors has potential to measure wind velocity. Under the same temperature and electric condition, such as stable room temperature, provide a constant current to NTC thermistors for self-thermal. Put NTC thermistors in still air, at this time, the terminal voltage is the lowest. Then increase the wind velocity generally, and the terminal voltage increases accordingly. Thats because the flow air decreases t...(more)

Continued from last article. In actual liquid level measurement, the temperatures of the water and air are often not the same. When the air temperature is low and the water temperature is high, we cant judge NTC thermistor is in the water or air according to the voltage. However, if we know a temperature point and also the voltages of the air and the water at this temperature, then we can judge the NTC thermistor is in the air or in the water. That is to say, the liquid level and the temperature...(more)
Continued from last article. We are introducing liquid level measurement for NTC thermistor. In the water and air of the same temperature, and under the same electrical condition, a constant current is provided to NTC thermistor, and make the thermistor produce self-heat. The voltage of NTC thermistor is relatively stable after heat balance. Then put it into the water, the voltage of NTC thermistor rises. Thats because when NTC thermistor enters into the water, the temperature falls, resulting i...(more)
