The main features of the thermistor are:
①High sensitivity, its temperature coefficient of resistance is more than 10 to 100 times larger than that of metal, and it can detect temperature changes of 10-6 °C;
② Wide operating temperature range, normal temperature devices are suitable for -55℃～315℃, high temperature devices are suitable for temperatures higher than 315℃ (currently up to 2000℃), and low temperature devices are suitable for -273℃～-55℃;
③Small size, able to measure the temperature of voids, cavities and blood vessels in living organisms that cannot be measured by other thermometers;
④Easy to use, the resistance value can be arbitrarily selected between 0.1 ~ 100kΩ;
⑤It is easy to process into complex shapes and can be mass-produced;
⑥ Good stability and strong overload capacity.
