#1

Advantages of Thermocouple

1.Very wide temperature range (1.2 K to 2300 deg C)
2.Fast response time
3.Available in small sheath sizes
4.Low initial cost
5.Durable

Disadvantages of Thermocouple

1.Decreased accuracy comparing to RTD
2.More susceptible to RFI/EMI
3. Recalibration is difficult
4.Requires expensive TC wire from sensor to recording device
5.Difficult to verify
6.Not as stable as RTD

EMI/RFI?
What is the full form


#3

A thermocouple measurement requires two temperature measurements: the hot junction measurement and the cold junction measurement. The reported temperature is the addition of the two measurements. Each has an accuracy uncertainty.

Electromagnetic interference ( EMI ), also called radio-frequency interference ( RFI )
