SenseDisc Surface Temperature

The sensing component of Surface Temperature Sensor is NTC thermistor. It is sealed with an empty metal container. When it touches to object need to be measured, it has very quick response. NTC thermistor consists of manganese, cobalt, nickel and copper. It is manufactured by ceramics. All those metallic oxide are semiconductors because they are same as germanium and silicon in conducting modes. When the temperature is low, the quantity of carrier on those materials is low. Thus, its resistance is high. When temperature rises up, quantity of carrier increases and resistance drops. NTC thermistor can be widely used to measure, compensate temperature and restrain surge current.
