- Vibration meter or analyzer is an electronic device that is able to process vibration signals. The sensor is generating a Voltage signal while it is shaking on the machine. This voltage signal is transferred through the cable to your vibration device. But your vibration device will not show you volts.
- A seismometer is a device that is sensitive to vibrations. It works on the principle of a pendulum: a heavy, inert mass with a certain resistance to movement (i.e. inertia) due to its weight is suspended from a frame by a spring that allows movement.

Understanding Amplitude Measurement Instruments
When discussing instruments that measure the amplitude of a vibrating body, both vibrometers and seismometers play crucial roles. Let's break down their functions:
1. Vibrometers
- Vibrometers are specifically designed to measure the vibrations of a body.
- They quantify the amplitude of vibration, which is essential for assessing structural integrity and mechanical performance.
- Commonly used in engineering applications, they can provide real-time data on vibration levels.
2. Seismometers
- Seismometers are used primarily to detect and measure seismic waves produced by earthquakes or other ground motions.
- They also measure the amplitude of these vibrations, providing crucial data for geologists and engineers.
- The amplitude readings from seismometers help in understanding the energy released during seismic events.
3. Combined Functionality
- Both instruments serve the purpose of measuring amplitude, albeit in different contexts—vibrometers in mechanical systems and seismometers in geological phenomena.
- Their ability to measure the vibrations and associated amplitudes makes them essential tools in their respective fields.
Conclusion
Given that both vibrometers and seismometers measure the amplitude of vibrating bodies, the correct answer to the question is indeed option 'C', indicating that both instruments are capable of this measurement. Understanding their unique applications enhances our ability to analyze and interpret vibrational data effectively.
