In terms of temperature measurement, what does RTD stand for?

In the context of temperature measurement, RTD stands for "Resistance Temperature Detector." This type of sensor operates on the principle that the resistance of certain metals changes in a predictable way with temperature. Typically made from pure platinum, RTDs are known for their accuracy and stability, which makes them suitable for a wide range of industrial and laboratory applications.

RTDs deliver precise temperature readings over a wide range and their resistance increases proportionally to an increase in temperature. This relationship allows for accurate transformations of resistance measurements into temperature values. When implementing your temperature sensing applications, understanding the workings and correctly identifying RTDs is crucial, particularly because they represent one of the most reliable and repeatable temperature measurement technologies in use today.
