Thermistor - Working, Types - NTC & PTC,Uses,Comparison ...

Another type of sensor, that is made using the PTC Thermistor, is ofcourse the temperature sensor. Here when these PTC are used, only their steep region of R/T characteristic is considered. Also, the resistance is regarded as a function of ambient temperature given that varistor effect is excluded. These sensors come in handy at places where temperature limit is needed for protection purposes.
