GrindoSonic Impulse Excitation Technique

GrindoSonic Impulse Excitation Technique

Rapid and Simple; An alternative to destructive testing with excellent correlations existing between breaking load and natural frequency.

With Impulse excitation flaws such as cracks, density changes, tensile strength, changes in bulk properties become detectable in otherwise difficult to test materials.

GrindoSonic MK-7

for non-destructive measurements of Material Characteristics based on Impulse Excitation Technique (IET).

Grindosonic MK-7

Materials like:

  • Grinding wheels
  • Refractory bricks
  • Brake linings
  • Ceramics
  • Composites
  • Concrete
  • Wood 
  • Cast iron and other coarse-grained metals
