Comparison between RTD and thermistor

Difference between RTD and Thermistors are given in the table below

RTD	Thermistor
It is made up of metals.	Thermistor is made up of semiconductor materials.
Since metals have a positive temperature coefficient (PTC) of resistance, its resistance is directly proportional to temperature	Since semiconductor materials have a negative temperature coefficient (NTC) of resistance, it’s resistance is inversely proportional to temperature.
Has linear resistance temperature characteristics	Has non-linear resistance temperature characteristics
Less sensitive to temperature	Highly sensitive to temperature.
Has wide operating range i.e., –200°C to 650°C	Has a narrow operating range i.e., –100°C to 300°C
Larger in size	Smaller in size.
Costlier when compared to a thermistor.	Cheaper when compared to RTD
Has low self-resistance.	Has high self-resistance.
Provides high degree of accuracy and long-term stability.	Provides an accuracy of ± 0.01°C.
Used in laboratory and industrial applications	Used in dynamic temperature measurement
