Aircraft Engine Thermocouple Segment and Pickups
Where is the thermocouple segment located, and how many pickups per segment?
a) Located in the exhaust, with one pickup per segment.
b) Located in the intake, with one pickup per segment.
c) Located in the APU, with multiple pickups per segment.
d) Located in the accessory drive gearbox, with no pickups.
Final answer:
Answer:
A thermocouple segment is located in the engine's exhaust system, with one pickup per segment used to measure temperature and manage engine performance.
The thermocouple segment mentioned in the question is typically located in the exhaust system of engines, such as those in airplanes or power generation systems. It is part of a thermocouple assembly, which is used to measure temperature and provide this information for engine management purposes.
Generally, for each thermocouple segment in the exhaust, there is one pickup, also known as a thermocouple junction. This pickup is responsible for detecting the temperature change and converting it into an electrical signal.
The correct answer to this question is option a) Located in the exhaust, with one pickup per segment. This placement allows for accurate measurement of the high temperatures produced by the engine exhaust, which is crucial for monitoring and controlling engine performance.
