Metal detector for webs and plates


  • Precise metal detection due to multi-segment sensor for particularly flat products
  • Highest sensitivity through 4-quadrant technology
  • Rotating sensor traverse adapts perfectly even to vertical or inclined product flow
  • Freely selectable widths up to 7 m and more
  • Intuitive control and easy installation with auto-calibration and TeachAssistant
  • Maintenance-free due to automatic balance and calibration control


Metalldetektor COMBI mit 4 Sensorplatten


The METAL SHARK® COMBI is a rotatable multi-segment sensor that is typically used over very flat products such as fiber wood, plastic boards, fabric or nonwoven, paper or plastic webs.

It detects the smallest metal particles from 0.5 mm and locates their position in defined segments of the fabric.

The METAL SHARK® COMBI is available for widths up to 7,000 mm and more. It can also be operated without problems in humid workplaces with ambient temperatures from -10˚C to +40˚C and product temperatures up to 90°C.
