The METAL SHARK® BIG pba with its rectangular tunnel and its fairly low clearance is specifically designed for the monitoring fiber mats, MDF, OSC or chipboard as well as other panel materials.

It is typically installed with a flat belt conveyor.

Due to its 3D detection technology, the METAL SHARK® BIG pba detects magnetic as well as non-magnetic metal contaminants (iron, stainless steel, aluminum, etc.) accurately and reliably even in challenging conditions.

Delivery Scope

  • BIGpba detection unit (sensor)
  • Control unit electronic control cabinet with current METAL SHARK® electronics


  • Protection of tools and machines from metal objects such as nails, bolts or screws
  • Monitoring of particularly large but flat products e.g. paper, cardboard, paper and related upstream products
