The purpose of this document is to familiarize the reader with the resistance temperature detector (RTD) as a method of temperature measurement in real-time control applications, as well to introduce possible sources of error and how to correct them. There is an extensive portfolio of semiconductor sensing technologies that allow for new capabilities in efficiency, performance, and low-latency response in real-time control systems. Therefore, alternative temperature measurement methods and their corresponding advantages are discussed in this document.
