Abstract
Un Metal Detector con trasduttori elettromagnetici sfalsati e circuito correttore delle disuniformità, rivolto alla rivelazione del passaggio di masse metalliche ed in particolare di armi attraverso accessi controllati.Consiste in due trasduttori Tx e Rx, ciascuno formato almeno da due avvolgimenti fra loro sfalsati in altezza ed in una circuiteria elettronica mediante cui i segnali in ricezione vengono analizzati, poi confrontati fra loro e con i valori memorizzati in una tabella per dedurre il coefficiente correttivo con cui il segnale predeterminato fra quelli ricevuti deve essere amplificato per compensare e quindi correggere la disuniformità di rivelazione in altezza del pavimento del Metal Detector.
