MG-ST-200

Industrial FRF testing system


The MG-ST-200 is the evolution of MG-ST-100 that allows to make a double test on same part, usable on two different machines.
It is the fast and cost effective FRF solution for verifying voids, cracks, geometry, density or other kind of variations on parts.


Every part, product or component has its unique acoustic resonant signature that reflects its composition, dimensions and stiffness. The resonant frequencies (eigen-frequencies) are almost exactly the same from good part to part, however they will change when internal or external changes occur . Any deviation from the expected signature indicates a variation of the part characteristics or in the manufacturing process.

The testing procedure consists of acquiring the sound response of the excited part and analyse a predefined set of selected frequencies. The test takes less than 1 second, allowing cost-effective and efficient quality control.
