Abstract

En fremgangsmåte for å overføre signaler gjennom et metallrør omfatter trinnene med å overføre modulerte elektromagnetiske signaler gjennom en ikke-magnetiske metallseksjon av metallrøret, påvise signalene eller et felt tilknyttet signalene, og regulere eller overvåke innretninger eller drift tilknyttet metallrøret som svar på signalene. Et materiale, en geometri, en behandling og legering av den ikke-magnetiske metallseksjon velges for å optimalisere signaloverføringen derigjennom. Et system for å utføre fremgangsmåten omfatter metallrøret og den ikke-magnetiske metallseksjon. Systemet kan også omfatte en senderanordning konfigurert for å beveges gjennom metallrøret og sende ut de elektromagnetiske signaler, en antenne på utsiden av den ikke-magnetiske metallseksjon konfigurert for å påvise de elektromagnetiske signaler, og en mottakerstyrekrets konfigurert for å generere styresignaler som svar på de elektromagnetiske signaler.
