Thermistor has a good development prospect
Thermistors are widely used in household appliances, electric power industry, communications, military science, aerospace and other fields, and their applications are so extensive due to their unique properties, which can not only be used as measuring components (such as measuring temperature, flow, Liquid level, etc.), can also be used as control components (such as thermal switches, current limiters) and circuit compensation components. The advantages of thermistors are:
1. Small in size, it can measure the temperature of voids, cavities and blood vessels in living organisms that cannot be measured by other thermometers;
2, easy to use, the resistance value can be arbitrarily selected between 0.1 ~ 100kΩ;
3. Wide operating temperature range, normal temperature devices are suitable for -55°C ~ 315°C, high temperature devices are suitable for temperatures higher than 315°C (currently up to 2000°C) low temperature devices are suitable for -273°C ~ 55°C;
4, good stability, strong overload capacity;
5, high sensitivity, its temperature coefficient of resistance is more than 10 to 100 times larger than that of metal;
6. It is easy to process into complex shapes and can be mass-produced.
These advantages make thermistors should be widely used, and the development prospects are extremely broad.
