The temperature measurement is mandatory in any industrial process. Now-a-days, PT100 is very common type temperature sensor. Through this lesson we'll learn the pt100 sensor in details.

9. Difference between pt100 and k type thermocouple.
- PT 100 is a types of RTD that means resistance temperature detector.
- Platinum resistance temperature detector is a device with a typical resistance of 100 Ω at 0°C
- That's why it is called Pt100.
- It changes resistance value as its temperature changes following a positive slope (resistance increases when temperature is increasing).
- A RTD can typically measure temperatures up to 850 °C.

The relationship
between resistance and temperature is relatively linear as shown above.
