Discussion: Types And Selection Of Resistance Temperature Detectors (RTDs)
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?
