Measurement Of Temperature By Thermistor

Measurement Of Temperature By Thermistor

A thermistor is a temperature-sensing element composed of sintered semiconductor material which exhibits a large change in resistance proportional to a small change in temperature. Thermistors usually have negative temperature coefficients which means the resistance of the thermistor decreases as the temperature increases.

Thermistor Accuracy

Thermistors are one of the most accurate types of temperature sensors. Thermistors have an accuracy of ±0.1°C or ±0.2°C depending on the particular thermistor model. However thermistors are fairly limited in their temperature range, working only over a nominal range of 0°C to 100°C . 

Thermistor Stability

Finished thermistors are chemically stable and not significantly affected by aging.
