Protection for crushers, grinders and other machines

Metal detector PSQ RA

  • Extremly resistant to weather, dirt or impact of stones and also immune to vibration
  • Simple and timesaving mounting: belt must not be devided due to a devidable probe
  • Can be used in the proximitry of frequency converters
  • Low difference in sensitivity on different sensing heights above the belt
  • CE-certified


Metalldetektor PSQ im Einsatz in der Recyclingindustrie


The PSQ RA series of metal detector (opterating with a frame-probe) detects all kinds of metal, which means not only iron, but also aluminium, 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. It’s frame can be devided and easily be built around the belt.

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