Negative temperature coefficient thermistor use common sense

Negative temperature coefficient thermistor is a kind of commonly used type thermistor, mainly by manganese, cobalt, nickel, copper and other metal oxides as element, electronic ceramics craft process of a kind of sensitive element. When we were in the use of negative temperature coefficient thermistor for its use knowledge to understand? The following projects to detailed introduce for everybody.

NTC (negative temperature coefficient thermistor is the most important performance life

long-life NTC thermistor, is the understanding of NTC thermistor, emphasized the importance of life of resistance. NTC thermistor is the most important is the life, in stand up to all kinds of high precision, high sensitivity, high reliability, super high temperature, high pressure after the test, it is still a long time and stable work.

life is an important performance of NTC thermistor, and there is a dialectical relationship, the sensitivity of other parameters, such as precision. A NTC resistance, long service life, must first to ensure the performance of other play; And other excellent performance, depends on the production process to achieve a certain technical level, this may make the NTC's long life.

a lot of high-tech electronic products, in the ultra high temperature, super high and other harsh conditions, need thermistor play a stable temperature control, temperature measurement function, most manufacturers devotion to the precision of the NTC thermistor, sensitivity, drift value such as the stability of the conventional performance, ignore the life span of the resistance, the cause for the NTC unable to work long hours and affects the use of electronic products. In this way, all the accuracy, sensitivity, high temperature resistant, etc. , all become meaningless.

NTC (negative temperature coefficient thermistor history

the NTC thermistor has experienced a long development stage. In 1834, scientists found for the first time the characteristics of the silver sulfide has negative temperature coefficient. In 1930, scientists found that the cuprous oxide - Copper oxide also has a negative temperature coefficient of performance, and successfully applied in the aviation instrument of temperature compensation circuit. Then, due to the continuous development of the transistor technology, major progress was made in the study of the thermistor. NTC thermistor is developed in 1960.

NTC (negative temperature coefficient thermistor temperature range

its measuring range is commonly - 10 ℃ ~ + 300 ℃, also can do 200 ℃ ~ + 10 ℃, and even can be used to + 300 ℃ ~ + 1200 ℃ environment for temperature measurement.

negative temperature coefficient thermistor thermometer precision can reach 0. 1 ℃, the temperature time can be as little as 10 s. It is not only applicable to the granary temperature measuring instrument, and can be applied to food storage, medicine and health care, scientific farming, Marine, deep well, high temperature measurement, glacier, etc.
