PTC Thermistor
Thermistor is a kind of sensitive element, which can be divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC) according to different temperature coefficient. The typical characteristic of thermistor is that it is sensitive to temperature and shows different resistance values at different temperatures.
Both PTC and NTC could be provided.
Advantages:
1. The working temperature range is wide, the normal temperature device is suitable for - 25 ℃ ~ 125 ℃
2. small size and can measure the temperature of voids, cavities and blood vessels in the organism which can not be measured by other thermometers;
3. It is easy to use and the resistance value can be selected from 0.1 to 100 K Ω;
4. easy to process into complex shape and can be mass produced;
5. Good stability and overload capacity.
6. Can be packaged in bulk bags or tape&Reel packaging.
