Structure and Dimensions：

These sensors are used to measure motor coil temperature. This kind of high quality MFP temperature sensor makes the measurement error further reduced, so generally does not need to be modulated. The design and material of the sensor determine all the technical parameters. The design of its structure makes the reaction time much shorter and more durable.

The NTC temperature sensor is a thermistor with a negative temperature coefficient and a significant decrease in resistance as the temperature rises. It is made of manganese (Mn), cobalt (Co), nickel (Ni), iron (Fe), copper (Cu) and aluminum (Al) and other metal oxides as the main material, and is made of ceramic process.

NTC thermistor is the relationship between resistance and temperature approximation in conformity with the law of exponential function, and can make the resistance temperature characteristic curve, into a one-to-one relationship between resistance and temperature, using a resistance temperature characteristic of the NTC thermistor, temperature can be calculated by measuring resistance value of high and low, it is the foundation of the NTC thermistor temperature measurement.

The main characteristics of NTC thermistor application in temperature measurement are: (1) high sensitivity, the resistance temperature coefficient is 10 ~ 100 times larger than the resistance temperature coefficient than the metal, the temperature coefficient is -3% ~ -6%, can easily detect the temperature change of 0.1℃; ② wide operating temperature range, room temperature device is suitable for -55℃ ~ 350℃ temperature range; Small size, the chip can be 0.3*0.3*0.2mm below or even smaller, can measure other thermometers can not measure the space, cavity and biological blood vessel temperature; (4) Easy to use, resistance value can be arbitrary choice between 0.1 ~ 1000kΩ; ⑤ easy to process into complex shapes, can be mass production; ⑥ low price, high cost performance.

As an enterprise focusing on the research and development and production of NTC thermistor in the industry, the production of temperature measurement type NTC thermistor has the characteristics of high reliability, high accuracy, good consistency, good stability, strong interchangeability, strong versatility, low annual drift rate.
