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.
