Mechanical vibration is measured in three parameters:
** Acceleration (ms-2 where g) measured by accelerator)
** Displacement (µm) measured by (Displacement or proximity sensor)
** Speed (mms-1) measured by (Speed Sensor/ Velocimeter)
Vibration sensors are used for inspection and measurement of machine vibration in service
Several defects such as an alignment defect, an imbalance defect, the resonance phenomenon can be the source of the deterioration of the mechanism for this we resort to the installation of these sensors to control and monitor the machines.
