Vibration measurement

Initial unbalance is measured indirectly. A rotating unbalance generates a centrifugal force acting at the bearings. This results in vibration which is measured. For each plane an accelerometer is mounted in radial direction and connected to the inputs of the InnoBeamer device.
Vibration measurement

Vibration measurand

1. Vibration measurand
Vibration can be displayed as acceleration, velocity or displacement. Most common in the machine building industry is vibration velocity which is also used in machine condition monitoring to ISO 10816.


2. Characteristic
RMS or peak values can be measured to characterize vibration.

Signal source

3. Signal source
Selects the physical signal input for vibration of the USB device InnoBeamer.


4. Gain
Selects the physical gain of the USB device InnoBeamer for vibration. Auto ranging must not be used for balancing.
