What does RTD stand for in relation to temperature measurement?

Resistance Temperature Detector (RTD) is a type of temperature sensor that operates based on the principle that the electrical resistance of certain materials changes with temperature. Unlike some other temperature measurement devices, RTDs provide high accuracy and stability over a wide temperature range, making them ideal for industrial applications and gas turbine systems in particular.

RTDs typically use pure platinum as their sensing element because of its predictable and repeatable resistance-temperature characteristics. They are commonly utilized in various systems for precise temperature monitoring, ensuring efficient operation and safety in machinery such as gas turbines. The other options listed do not accurately describe what RTD stands for or the functions they serve in temperature measurement.
