TEMATE ST-LA is designed for volumetric inspection of thin laminated products such as coin stock and bearings. Well suited for steel, copper, brass, aluminum and other multi-layered materials.


  • Non-contact EMAT technique.
  • Guided wave technique capable of detecting surface and sub-surface invisible lamination defects.
  • Detects defects along the rolling direction (longitudinal and oblique).
  • Permits inspection of rough and dirty materials.
  • Not affected by changes in color or reflectivity.
  • Requires minimum amount of sensors to cover large spans of material.
  • Available for ferrous and non-ferrous materials.
  • Exclusive flexible sensor technology that conforms to the surface of the material.
  • Easy to install, simple to operate with very low maintenance and operating costs compared to other methods.
  • Completely automated operation. Easy to program and interpret results.
