    Application

    ● Air conditioners, refrigerators, freezers, water heaters, water dispensers, heaters, dishwashers, disinfection cabinets, washing machines, dryers and other home appliances.
    ● Automobile air conditioner, water temperature sensor, intake air temperature sensor, engine
    ● Switching power supply, UPS uninterruptible power supply, frequency converter, electric boiler, etc.
    ● Intelligent toilet, electric blanket, etc.


    Working principle of temperature sensor
    Using the NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
