Question 1 of 27070

Accelerometers are generally used on gas turbine engines to sense which of the following?

🔍 Key Concepts

• Accelerometer function – what physical quantity does an accelerometer actually measure? • Differences between speed, rate of change of speed (acceleration), and vibration in rotating machinery. • Common monitoring points on gas turbine engines for protection and condition monitoring.

💭 Think About

• Which option describes something related to acceleration or vibration, rather than just speed or control logic? • On a rotating shaft, what does a sensor mounted to the casing typically detect when the shaft is out of balance or a bearing is failing? • If you had to protect a gas turbine from mechanical damage due to imbalance or resonance, which type of measurement would be most useful?

✅ Before You Answer

• Confirm what an accelerometer measures in basic physics terms. • Check which choices describe a control or speed signal versus a mechanical condition (vibration/acceleration) measurement. • Eliminate any options that do not directly involve acceleration or vibration of the engine structure or rotor.
