Metal detector QLC/QLCTA


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

  • Good sensitivity (M10 nuts) at belt speed of 0.3 – 6 m/s
  • Very simple operation
  • Can be used close to frequency conver-ters, only 2 m minimum distance between probe and motors or magnets
  • Belt widths from 500 mm to 2,000 mm
  • Monitoring and display of internal para-meters
  • Optional: Realization as tandem for higher debris heights
  • Optional: complete suppression of magnetite Fe3O4


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.


  • Sensor and coaxial cable
  • Metal alarm relay with 2 potential-free changeover contacts, switching capacity 230V/6A
  • Iron, non-ferrous (e.g. aluminium or copper), largely ignores ores Optional: complete blanking of magnetite Fe304
  • 500 – 2,000 mm
  • 0.3 – 6.0 m/s
  • IP55
  • -20° C up to +55° C
  • 230V 15 Hz +/- 15%, typ. consumption 15 VA
  • Sheet steel housing, prepared for wall mounting, 9 kg
  • Mono (QLC) for lower debris heights, tandem (QLCTA) for higher debris heights
  • From steel nuts M10

Delivery Scope

  • Detection unit QLC (single probe) or QLCTA (tandem probe)
  • Control unit in sheet steel housing, prepared for wall mounting, 9 kg


  • Protection of tools and machines from metal parts such as machine parts or screws
  • Monitoring of particularly large and heavy products in recycling, mining or slag processing
