In our daily life, in fact, it is more or less connected with the temperature sensor all the time. It can be said that life is completely inseparable from the NTC temperature sensor. Basically, all small and small appliances involving temperature control will be applied to NTC temperature sensors. For example, the most commonly used smart rice cookers, microwave ovens, washing machines, air conditioners, refrigerators, etc.

The maximum temperature of the commonly used rice cooker is generally controlled at 103 ° C, the thermal insulation temperature is controlled at 65 ° C, and there is a temperature control device inside.
 
It is mainly composed of heating disk, temperature limit, insulation switch, leverage switch, current limiting resistance, indicator lights, sockets, etc. It is divided into two processes. When cooking After cooking, use the preheating rice of the electric heating dish after power off, and then the thermal insulation is 65-70 ° C.
 
The temperature control of the rice cooker is detected by metal slices. The metal sheet is made of two different metal slices. It is installed on the heating plate to feel the temperature of the heating disc. The heating temperature is to heat up by heating plates. The heating disk is equipped with a temperature control component temperature sensor. Through the control of the temperature sensor, it is specifically pointed out why the temperature sensor should be controlled. For 100 ° C, increase the increase in gas pressure. When cooking rice cookers with rice cookers, when covering the top cover, a relatively sealing space is formed in the rice cooker. During the heating process Ascending, the boiling point of the water rises, and the rice cooker does not have a temperature sensor element to control the temperature, which can easily cause the rice cooker to explode and cause danger. When the power supply is reduced, the metal piece will restore the original state to continue to power, and the characteristics of the temperature sensor are exactly suitable for the temperature control of the rice cooker.
