Abstract

L'invenzione concerne un Metal Detector perfezionato a passaggio, provvisto di avvolgimenti trasmettitori-ricevitori Tx-Rx connessi, attraverso adatti amplificatori A, D, ad un Gruppo Logica di Analisi e Controllo LAC nel quale i segnali vengono comparati, nonché provvisto di almeno un avvolgimento ricevitore ausiliario CC da ciascun lato del passaggio controllato atto a fornire informazioni al gruppo LAC su masse metalliche transitanti lungo traiettorie ad esso prossime, allo scopo di uniformare la sensibilità di intercettazione sull'intero varco di transito, anche al passaggio simultaneo di più masse metalliche.
