I am making a report and how does EGT of an aircraft, either turbo or piston engine, work? Can you please give me the procedures... Like where it starts and being transferred to where and stuff. Thank you!
From all the NASA reports I could find they mostly use Thermocouples. They also use RTDs which sometimes are called PT100. I am not sure if termistors are used. There is research on optical measurement, but right now I would say that Thermocouples and RTDs are the common way to measure EGT.
