Ya i am agree with 2one but the the measure difference
between RTD & Thermocouple on their working principle.
1)RTD is limited up 500-700 degree celcius it is
manufactured up to 1000 degree celcius on special cases.
2)It is mainly used for measurement up to 500 degree
celcius.
3)It is available in 2,3 or 4 wire configuration.
4)We can use transmitter or card when we are interfacing
the RTD with DCS.
5)It's accuracy is good in comparision of Thermocouple on
small Temperature ranges.
Thermocouple
1)It is based on seeback effect.
2)It is generaly use for higher Temperature ranges up to
3000 degree celcui(ceramic type thermocouple in special
case)
3)It is not a 3,4 wire device.
4)Grounded thermocouples are used where fast response is
required.(Thermocouple tip is welded with thermowell.
5)O/P is mV.
