The main types of vibration signals used in the systems for equipment vibration analysis are the signals of vibration acceleration, vibration velocity, and vibration displacement. The parameters of these signals (RMS value, peak value) are in common use in different diagnostic and vibration-survey systems for equipment condition control.
In order to receive the required signal it is allowed to use appropriate sensor as an end device: piezoaccelerometer – for vibration acceleration parameter, inductive sensor of vibration velocity - for vibration velocity, displacement sensor – for vibration displacement.
But most devices and systems for vibration measurement use vibroaccelerometer as an end device, and the integration operations are used for acquisition of the signal of vibration velocity and vibration displacement.
