Industrial Instrumentation Tutorial 27 - Temperature Measurement 7 - Thermistor
In this tutorial, we will discuss the basics and operational principles of Thermistor. We will see their characteristic features, range of measurement, material composition, advantages and limitations. The thermistor is one of the three main types of electrical type temperature measurement method where change in temperature leads to change in the electrical parameter of the sensor, which is the resistance in this case. The thermistor generally has negative temperature coefficient, i.e. the resistance decreases with increase in temperature, but a handful of thermistors have positive temperature coefficient as well.
The thermistors are generally made up of semiconductor materials, oxides of pure metals.
