Thermistor temperature sensor

What is Thermistor?

What is a thermistor temperature sensor? 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. For the most part, thermistors  have negative temperature coefficients which means the resistance of the thermistor decreases as the temperature increases.

Thermistors are one of the most accurate types of temperature sensors out on the market today. Depending on the particular thermistor they typically have an accuracy of ±0.1°C or ±0.2°C. However thermistors are fairly limited in their temperature range, working only in the range of 0°C to 100°C. The thermistor element is the simplest form of thermistor and is commonly used when space is very limited.

For applications requiring thermistors with linear response to temperature change, Thermometrics provides linear components. These applications consist of a thermistor composite for temperature sensing and an external resistor composite for linearizing. The standalone thermistor element is somewhat fragile and should not be used in a rugged environment. Thermometrics also offers thermistor probes which are thermistor elements embedded in metal tubes. Thermistor probes are much more suitable for industrial environments than thermistor elements.
