Detektor metala s impulsnom pobudom

Detektori metala s impulsnom pobudom su uređaji koji rade na principu mjerenja vremenskog odziva napona promatranog na prijamnoj zavojnici koji nastaje nakon naglog pada strujne pobude na odašiljačkoj zavojnici. U prisutnosti metalnog predmeta, sami predmet će spremiti dio energije reflektiranog imp...
