Launch of new In-Line system GrindoSonic® IL for 100% production QA-QC

The GrindoSonic® IL System is designed to integrate and fully automate the quality control process of objects in a production line.
As soon as for instance a braking pad, a ceramic tile or a grinding disk is in a defined location of a production line, the vibration measurement probe will be positioned against the object by means of a measurement arm. The impulse excitation device will hit the object with a small steel projectile, causing the natural frequency to be excited.

This frequency is measured and immediately displayed on the touch screen. Acceptance limits can be set up per batch and statistics can be done. An average of the accepted pieces and of the total number of pieces is calculated immediately.

Material properties such as elasticity, E- or G-modulus can also be measured.


  • non-destructive 100% Quality Assurance by measurements of elastic properties of materials in the production line
  • fully automated
  • OEM equipment can be integrated by line-builders
  • calculation of E- and G-modulus and Poisson’s ratio
  • an alternative to destructive testing as excellent correlations exist between breaking load and natural frequency
  • production process monitoring for launch and QA-QC
  • widest range of materials: ceramic, wood, composites, brick, concrete, ...
  • widest range of sizes from less then 100mg to 100ton
