A metal impurity in the material flow causes a change of the high-frequency field in the detection coil.
This change is detected by the Control Unit. Since the product flow itself may already have an influence on the field (which is referred to as a product effect), this behaviour can be stored in order to
avoid false activation caused by the product effect. For this purpose the equipment offers 28 storage
places for different products.
