Metal detector for stone and earth processing

Metal detector QLC/QLCTA

  • Monitors bulk materials in the building materials industry or mining
  • Self-adjusting and extremely easy to install
  • High-quality components ensure reliability and long service life
  • Detects ferrous and non-ferrous metals, iron oxide and ore are ignored
  • Probe and amplifier are immune to vibration and resistant to weather, dirt and stone chips
  • Particularly robust and easy to clean


Metalldetektor QLC für Einsatz im Bergbau oder der Wertstoffverarbeitung


The QLC and QLCTA metal detectors offer good metal sensitivity for monitoring bulk materials in the mining and construction materials industry.

At a belt speed of 0.3 – 6.0 m/s they easily detect metal parts of the size of about M10 nuts and larger.

For higher sensitivity (M6 nuts) at a belt speed of max. 4.0 m/s we recommend the metal detectors SQ and SQTA.
