Square Metal Detector SD3-45B Type

For inspection of large bag products and large box products, such as grain

System Square Metal Detector SD3-45B is suitable for inspection of products contained in large boxes and bags, such as rice, wheat flour, and cereals, etc. It copes with conveyance of heavy items (20kg) on the conveyor

System Square Metal Detectors MetaHawk3 has 3 kinds of inspection functions:

  • New System “V Mode Inspection”
    As the product features are visualized using multiple phases, even fine changes are identified to achieve high sensitivity.
  • Advanced ECP Function
    In the MetaHawk3, this ECP function has been further advanced using the leading-edge data analysis technology. Use of this function makes it possible to precisely detect products containing water content or salt content with large effects as well as products with small effects.
  • 2-Frequency Inspection
    Both Fe and SUS foreign objects can be detected with high sensitivity.
