Comparison of Sensor Types

	Thermocouple	Platinum Resistance Thermometer	Thermistor
Sensor	Thermoelement, two dissimilar metals/alloys	Platinum-wire wound or flat-film resistor	Ceramic (metal oxides)
Accuracy (typical values)	0.5 to 5.0°C	0.1 to 1.0°C	0.1 to 1.5°C
Long term Stability	Variable, Prone to ageing	Excellent	Good
Temperature range	-200 to1750°C	-200 to 650°C	-100 to 300°C
Thermal response	Sheathed – slow Exposed tip – fast 0.1 to 10 secs typical	Wirewound – slow Film – faster 1-50 secs typical	generally fast 0.05 to 2.5 secs typical
Excitation	None	Constant current required	None
Characteristic	Thermovoltage	PTC resistance	NTC resistance (some are PTC)
Linearity	Most types non-linear	Fairly linear	Exponential
