Question 108Gas Turbine - Assistant Engineer70% to pass
The lube oil scavenge pressure on the marine gas turbine shown in the illustration is sensed by which of the following? Illustration GT-0017
AI Explanation
The correct answer is C) Transducer.
The lube oil scavenge pressure on the marine gas turbine is sensed by a transducer. A transducer is a device that converts one form of energy into another, in this case, converting the mechanical pressure into an electrical signal that can be monitored and used for control purposes. This is the standard method for measuring pressures in marine gas turbine systems.
The other options are incorrect because: A) A manometer is used to measure pressure visually, not electronically. B) An RTD (Resistance Temperature Detector) is used to measure temperature, not pressure. D) A probe is a general term that does not specifically indicate the sensing mechanism, which in this case is a transducer.
