Advantages of Thermistor | disadvantages of Thermistor
This page covers advantages and disadvantages of Thermistor. It mentions Thermistor advantages or benefits and Thermistor disadvantages or drawbacks.
Introduction:
Thermistors are made using semiconductors.
They have negative temperature coefficient i.e. resistance decreases with
increase in the temperature.
The figure-1 depicts resistance versus temperature curve of Thermistor. It can be used for low temperature measurement. It can measure from -1000C to +2600C.
➨Sensitivity order: Thermistor > RTD > Thermocouple
➨Linearity Order: RTD > Thermocouple > Thermistor
