The Tui Technology Acoustic Grader is the modern technology for measuring stiffness of boards in a sawmill by tapping the end of a board and measuring resonant frequency.

Tui Technology can also tailor the solution to:
  • Add a separate weigh station from one of our partners.
  • Add our board measurement systems for width, thickness and length.
  • Provide Tui sorting software with Rockwell and Siemens PLC options.
  • Provide a marking system if the grade or density needs to be marked on the boards.

The benefits

  • Tui Technology is able to provide a complete solution with integration to your existing control and measurement systems.
  • Streamlining sorting for density and stiffness in green mills, saving drying capacity downstream.
  • Can be used on its own or combined with Machine Stress Graders in dry mills.
  • Easy to install.
  • Uses readily available parts, including National instruments.
  • Built on the Labview software platform (industry standard).
