RTDs are more accurate and reliable than thermocouples

  RTDs are more accurate and reliable than thermocouples. You should also understand that RTD's sensing element is a resistor that changes resistance with temperature and it is connected to the control circuitry through a wire. Answer the following: In order to select the suitable detector, what materials should be used as sensing elements and wire materials for RTDs? How are thermocouples types and temperature ranges involved?
