Vibration upto 100 kilo hertz can be most accurately measured by a ________________ type accelerometer ?
Correct answer: A. Piezoelectric
- A. Piezoelectric
- B. Preloaded spring
- C. Bonded strain gauge
- D. None of these
Explanation
Piezoelectric accelerometers are well suited to very high-frequency vibration because their stiff sensing elements have a broad high-frequency response, extending toward 100 kHz. Strain-gauge and spring-based types are generally less suitable at such frequencies.
