    High Precision NTC Temperature Sensor High Thermal Conductivity Alumina Shell Seal

    High Precision NTC Temperature Sensor High Thermal Conductivity Alumina Shell Seal

    NTC temperature sensor is a commonly used temperature measuring instrument. It is generally composed of NTC thermistor, probe (metal shell or plastic shell, etc., extension lead, and metal terminal or connector). Its main feature is that the temperature within the working temperature range- The voltage relationship is a straight line. This second development of temperature measurement and temperature control circuit design can complete the temperature measurement or temperature control circuit design without linearization processing, simplifying instrument design and debugging.

    What is the principle of the ntc temperature sensor?

    The principle of the ntc temperature sensor is to use the NTC thermistor to drop rapidly as the temperature rises under a certain measurement power. 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.


    Negative temperature coefficient thermistors are made of metal oxides such as manganese, cobalt, nickel and copper, and are manufactured by ceramic technology. These metal oxide materials all have semiconductor properties, because they are completely similar to semiconductor materials such as germanium and silicon in terms of conductivity. When the temperature is low, the number of carriers (electrons and holes) in these oxide materials is small, so its resistance value is high; as the temperature increases, the number of carriers increases, so the resistance value decreases. The variation range of NTC thermistor at room temperature is 100~1,000,000 ohms, and the temperature coefficient is -2[%]~-6.5[%]

    (Highest tolerance can be reach ±0.02℃) (Years of drif rate ≤1‰)
