The temperature coefficient is divided into a positive temperature coefficient thermistor and a negative temperature coefficient thermistor. The positive temperature coefficient thermistor (PTC) has a higher resistance value at higher temperatures, and the lower the resistance value of the negative temperature coefficient thermistor (NTC) at higher temperatures, they belong to the semiconductor device. This article talks about the thermistor in the rice cooker, let's take a look!
The new rice cooker is made of a thermistor, and the old-fashioned rice cooker is made of magnetic steel. The new type of rice cooker is generally computer type, with light touch buttons or touch buttons. The old-fashioned Mechanical button. In general, the NTC-negative temperature coefficient thermistor sensor is in the bottom or part of the pot and is now popularly covered inside the sensor.
Can the thermistor in the rice cooker be removed? This is not to be used, because the thermistor is to control the temperature of the rice cooker. On the one hand, it will not overheat, and the other is convenient for it to jump to the heat preservation state when it reaches the cooked rice, so it must be used. When choosing a thermistor, the life is guaranteed. The purpose is not to be damaged, but also to use it correctly!
