What is the different between of rtd and thermocouple ?
Answer Posted / b v s rayudu
RTD works on PTC and exhibits linear characteristics in some region. Platinum material is mostly used, response is slower, high accurate and signal conditioning techniques are bit easier. For RTDs separate excitation required.
Thermo couples (TC) works on Seebeck effect, exhibits exponential characteristics, faster response, cold junction compensation is the disadvantage, separate excitation not required, output signal level is very low.
