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.
