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 |
Inexpensive to moderate |
