The lube oil scavenge pressure on the marine gas turbine shown in the illustration, is sensed by a ___________. Illustration GT-0017

Correct Answer: Option C — transducer

Pressure transducers convert mechanical fluid pressure into electrical signals for remote monitoring in the engine control room. Unlike manometers or probes, transducers provide the continuous, high-speed data required for modern gas turbine digital control systems to monitor scavenge oil pressure accurately during dynamic operational transients.
