Metal detector PSQ/RA

  • Resistant to weather, dirt or impact of stones and immune to vibrations
  • Simple and timesaving mounting
  • Can be used in the proximity of frequency converters
  • Low difference in sensitivity on different sensing heights above the belt
  • CE-certified
Metal detector PSQ/RA


  • Average sensitivity (from M40 nuts)
  • Nearly homogeneous sensitivity on the belt and in the upper layers of the product
  • Can be used close to frequency converters, only 3 foot minimum distance between probe and motors or magnets
  • Passage widths from 3 to 8 feet and heights can be adjusted as required
  • Robust design
  • Easy operation 
  • Monitoring and display of internal parameters 


The PSQ RA series of metal detector (operating with a frame-probe) detects all kinds of metal, which means not only iron, but also aluminum, stainless steel, copper or mild steel.

The specialty of this detector is a low difference between edge and center of probe aperture. Therefore it is especially suitable if the depth of burden on the belt is more tan 600 mm. Its frame can be divided and easily be built around the belt.

This metal detector prevents damage, avoids downtimes and produces significant savings on repair costs.

Delivery Scope

  • Detection unit/frame probe
  • Controller in steel or stainless steel housing (wall mounting)


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