Zusammenfassung
(EN)

A device for monitoring a product stream for undesired inclusions wherein, in a section of the product stream which is to be monitored, a material-specific detection signal is derived by means of a sensor system comprising a plurality of sensors arranged in a staggered manner under formation of a sensor row in the direction of transport of the product stream and by means of an evaluation circuit associated with said sensor system, by simultaneously adding the output signals of the individual sensors in an addition circuit in a correlated manner, said output signals originating from single products with regard to metal particles in the product stream to be checked, and using the output signal of the addition circuit as a detection signal for a metal particle to be discovered. At least one sensor of a sensor row, the output signals of which are added in an antiphase manner to the output signals of other sensors for difference-taking purposes, is provided for the compensation of interfering magnetic fields. The resulting difference signals are evaluated in an addition circuit in a correlated manner, said addition circuit being provided for forming the detection signal.
