The lube oil scavenge pressure on the marine gas turbine shown in the illustration is sensed by which of the following? Illustration GT-0017

Correct Answer: Option C — Transducer.

Modern marine gas turbines utilize electronic pressure transducers to monitor scavenge oil pressure. These devices convert mechanical pressure into electrical signals, allowing the control system to provide real-time data to the engine monitoring console, ensuring immediate detection of scavenge pump failure or oil system blockages during high-speed operation.
