Metal detection for textiles, fleece and webs

METAL SHARK® FL & FL compact

  • Reliably detects magnetic and non-magnetic metals in fabrics and webs
  • Particularly flat for optimal approach to ascending or descending product paths, FL compact additionally rotatable
  • Highest sensitivity with 4-quadrant technology
  • Intuitive control and easy installation with autocalibration and TeachAssistant
  • Maintenance-free with automatic balance and calibration control


Flachplatten-Metalldetektor METAL SHARK FL, senkrecht installiert für Metallinspektion von Vlies


The METAL SHARK® FL and FL compact metal detectors are usually used for the inspection of nonwovens, textiles and films.

Both detectors are particularly flat and available in widths of 1,000 – 4,000 mm. The FL compact is rotatably mounted so that it can also be adapted to sloping webs.

Due to the high sensitivity of the FL models, tiny magnetic and non-magnetic metal particles (e.g. iron, aluminium and stainless steel) are detected over the entire width.
