How does RTD Work

How Resistance temperature detector works?

Post by JG


The most popular RTD is PT-100, Platinum 100 Ohms, As all Metals have a Temperature Coefficient of Resistance. The Resistance of RTD increases with rise in temperature.

Even Copper wire can be used, but you need to have a very thin and long wire to make usable measurements.
