How is Vibration Measured
2021 10 26 It is a measure of how quickly the velocity of the component is changing The acceleration signal produced by the accelerometer is passed on to the instrument that in turn converts the signal to a velocity signal Depending on the user s choice the signal can be displayed as either a velocity waveform or a velocity spectrum.
