Question 153Gas Turbine - Assistant Engineer

The correct answer is D) Accelerometers. On marine gas turbines used aboard ships, vibration sensors are typically accelerometers. Accelerometers are devices that measure the acceleration of a structure, which can be used to detect and monitor vibration levels. This information is crucial for maintaining the health and performance of the gas turbine machinery. The other answer choices are not correct: A) Resistance temperature detectors measure temperature, B) Frequency synthesizers generate specific frequencies, and C) Transducers convert one form of energy to another, but they are not specifically used as vibration sensors on marine gas turbines.
