CASSEL Metalldetektor BIG pba

Metal detector for wide but thin products


  • Specially designed for the monitoring of wood, fibre boards or any wide but thin product
  • AutoSens technology for automatic adjustment of the sensitivity to the mat height
  • Maintenance-free with automatic balance and calibration control
  • Durable aluminium design: particularly robust and easy to clean
  • Highest sensitivity with 4-quadrant technology
  • Autocalibration and Teach Assistant for intuitive control and easy installation


Metalldetektor BIG pba in der Spanplattenverarbeitung


The METAL SHARK® BIG pba with rectangular opening at a rather low opening height is especially designed for monitoring fibre mats, MDF, OSC or chipboard as well as other panel materials.

The typical installation takes place around a conveyor belt with flat belt.

Using 3D detection technology, it detects magnetic and non-magnetic metal contaminants (iron, stainless steel, aluminium etc.) precisely and reliably even under difficult conditions.

Accessories & Extras

The METAL SHARK® BIG pba can be perfectly adapted to your production with various special designs and accessories.

Different temperature requirements are taken into account as well as complicated product requirements for metal detection.

The SHARKNET® software connects METAL SHARK® metal detectors with a central computer, providing centralized storage of all operating data plus batch and alarm documentation for HACCP and IFS compliance.
Super Power Drive (SPD)
Improves metal detection by -0.5 to -1 mm in industrial environments that do not meet electromagnetic compatibility standards, with different IP protection classes and ATEX Zone 22.
Temperature extension cold
Temperature range extended to -40°C / -40°F, resin seals remain elastic at low temperatures; special insulation, heated enclosure and other features.
Temperature extension hot
