Claes Fredö at Qring Technology International AB shows a high performance vibration isolation setup at MaxLAB IV.

Vibration Isolation Things you need to know truly to get effective isolation

Torsion Vibration Measurement and Analysis of Flue Gas Fan Typically, torsion vibration is weakly coupled (in the XYZ direction) with axial vibration when the drive system is straight. It can be nearly impossible to detect torsion vibration from axial vibration measurement because of this weak coupling.

How a Piezocable is built up and some of the Piezocable merits.

Piping Vibration Fatigue Risk Assessment Risk assessment criteria, application and limitations

Site Survey A Site Survey should be made before a laboratory decides on the best site. This example demonstrates how different ways of analysing a signal may affect the outcome of the survey .
