RTDs and thermocouples are typical analog sensing devices that measure what in a process?

Explanation:
RTDs and thermocouples are used to measure temperature in a process. RTDs detect temperature by the change in resistance of a metal with temperature, while thermocouples generate a small voltage that varies with the temperature difference between their junctions (the Seebeck effect). Their analog signals are fed to controllers to monitor and regulate heating or cooling. Other variables like pressure, flow, and humidity require sensors designed to respond to those specific physical properties, not temperature.
