Conveyor mounted needle detector for wide products -

Two models are available to detect metal contamination in wide products.

  • Flat search coil.
    Search coil is mounted under the conveyor belt. this type of detector will detect needle contaminations in the product passing on conveyor.
  • Tunnel type search coil.
    Product is passed through the needle detection unit (search coil) mounted on the conveyor belt. Detection sensitivity of this type of metal / needle detector is very high not only for needles (made of ferrous material) but as well to contaminations made of stainless steel and variety of alloys, brass, aluminum, etc.


  • Reliable detection.
    Stable, high sensitivity reliable detection.
  • Easy operation.
    Detection is carried out just by placing fabric on the conveyor belt.
  • Self calibrating electronic control unit.
    ND-820u evaluation electronics, include self calibration functions, this mean metal / needle detector will initially scan few times each product, analyze product characteristics, and automatically calibrate metal detector for the most optimum set-up.
    Each setup is stored in separate memory location, and can be recalled during product change over.
    Up to 200 product set-ups can be stored.
  • Automatic Reporting. Each routine manual test of the needle / metal detector can be documented, and automatic report can be printed by the ND-820 control electronics.
