The temperature sensor is filled with a platinum thermistor.
Platinum resistance temperature sensor is the use of metal platinum when the temperature changes its own resistance value also changes characteristics to measure the temperature, the display instrument will indicate the resistance value of the platinum resistance corresponding to the temperature value. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the medium layer within the range of the temperature sensing element.
Temperature sensor is one of the most widely used sensors, generally made of semiconductor material thermistor, it can convert the heat signal into electrical signal, automatic control, rice cooker, rice cooker automatic heating and insulation is accomplished with the help of temperature sensor.
