摘要

In order to detect and, as the case may be, display metal bodies in material being processed, conveyed or stored, in particular in harvested stalk/stem material, the device contains in a measuring space 1 at least two secondary coils 4 of a high-reactance transformer 5. At least one primary excitation coil 9 is connected to an AC voltage source 16 and the taps 13 of the secondary coils 4 are connected to an amplifier 20. <IMAGE>
