Description:
NTC Temperature Sensor is a detection element that feeds back the results to the system. It is also called thermistor or probe. Its principle is the resistance decreases rapidly when the temperature rises. NTC(Negative Temperature CoeffiCient)refers to thermistor phenomenon and material with negative temperature coefficient, and the resistance decreases exponentially when the temperature rises. NTC temperature sensor is mainly used in household air conditioner, auto air conditioner, refrigerator, stove, deep fryer, induction cooker, soybean milk machine, electric oven, kitchen utensils and appliances, floor heating,3d printers etc. temperature measurement and control.
