What is Resistance Temperature Detector (RTD)? Construction, Diagram & Operation
The resistance of conductors changes with change in temperature. This behavior is used for temperature measurement in RTDs. RTDs show Positive Temperature Coefficient (PTC) of resistance as their resistance increases with the increase in temperature. Metals like platinum, nickel and copper are commonly used as RTDs in industry.
