    NTC temperature sensor is a kind of thermistor and probe. Its principle is: the resistance value drops rapidly as the temperature rises. It usually consists of 2 or 3 metal oxides, mixed in a fluid-like clay, and calcined in a high-temperature furnace to form a dense sintered ceramic. Actual size is very flexible, they can be as small as 0.010 inches or very small diameter. There is almost no limit to the maximum size, but usually under half an inch applies.

    ►Different NTC thermistor using in the NTC temperature sensors with the following different operating temperature:


    Chip or MF52A,MF51E,MF55: temperature resist grade 125℃,actual temperature resist grade 150℃
    MF58: temperature resist grade 200℃,actual temperature resist grade 250℃
    MF51: temperature resist grade 200℃,actual temperature resist grade 250℃
    Special MF51: temperature resist grade 250℃,actual temperature resist grade 300℃
    Weldless chip:temperature resist grade 450℃,actual temperature resist grade 500℃


    ►Operating environment


    In the environment of high temperature,high humidty and high corrosion,we suggest to use glass sealed type thermistor as the core element.And MF51 type will be the best NTC thermistor in high humidity environment.


    ►Design considerations and procedure of temperature sensor:


    1. Choose the shape acoording to customer's design or assemble requirements, and confirm the thermistor.
    2. Confirm the thermistor element and other materials according to customers' requirement
    3. Choose the suitable resistance,B value and tolerance
    4. Choose suitable moisture-proof and insulation technology to meet customer's requirement
    5. Choose suitable encapsulation structure to meet performance requirements of mechanical shock resistance
    6. Meet customer's special requirements.



    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.
