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
Lead resistance effect Short cable runs satisfactory 3 & 4 wire – low.       2 wire – high Low
Electrical “pick-up” susceptible Rarely susceptible Not susceptible
Interface Potentiometric input. Cold junction compensation required Bridge
2,3 or 4 wire
2 wire resistance
Vibration effects/ shock Mineral insulated types suitable wirewound – not suitable. Film – good Suitable
Output/ characteristic From 10µV/°C to to 40µV/°C depending on type
approx. 0.4 W/°C -4% / °C
Extension Leads Compensating cable Copper Copper
Cost Relatively
low cost
Wirewound – more expensive
Film – cheaper
to moderate
