FRF System

The MG-ST-100 is designed to provide a rapid, simple and cost-effective NDT analysis. Based on the principle of acoustic signature, MG-ST-100 is the right solution for quality inspection and for dynamic measurement of parts integrity.

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, transform it in the frequency domain, and analyze a predefined set of selected frequencies. The test takes less than 1 second, allowing cost-effective and efficient quality-control.
