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.

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.

Thermistor curve

➨Sensitivity order: Thermistor > RTD > Thermocouple
