What does ntc mean in the experiment

NTC is the abbreviation of negative temperature coefficient, which translates to "negative temperature coefficient". In experiments, NTC is often used as a sensor and rheostat in temperature measurement and control circuits. The working principle of NTC is that with the increase of temperature, the resistance value will decrease; conversely, with the decrease of temperature, the resistance value will increase. Therefore, the temperature variation characteristics of NTC can be used for temperature measurement and control.

NTC sensors are widely used in industrial fields, such as automobiles, household appliances and life sciences. In the field of automotive electronics, NTC sensors can be used to detect the temperatures of engines, water tanks, exhaust pipes, brakes and heaters. In household appliances, NTC sensors can be used for temperature detection and control in washing machines, stoves, refrigerators and other electrical appliances. In life science, NTC sensors can be used in medical equipment, such as thermometers, thermometers and temperature controllers.

Difference between NTC sensor and PTC sensor

Both NTC sensor and PTC sensor are components for temperature detection and control based on the temperature-sensitive characteristics of materials. However, their resistance values change in opposite directions. The resistance of NTC sensor decreases with the increase of temperature, while the resistance of PTC sensor increases with the increase of temperature. Therefore, in practical application, the choice of NTC sensor and PTC sensor depends on the temperature change direction that needs to be controlled actually.
