The main features of thermistors.Microwave Sensor Module

　　① The sensitivity is high, and its temperature coefficient of resistance is more than 10 to 100 times larger than that of metal;

　　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℃) 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.

　　Due to the unique properties of semiconductor thermistors, in terms of applications, it can not only be used as a measuring element (such as measuring temperature, flow, liquid level, etc.), but also as a control element (such as thermal switches, current limiters) and circuit compensation element. Thermistors are widely used in household appliances, electric power industry, communications, military science, aerospace and other fields, and the development prospects are extremely broad.
