Abstract

"APARELHO E PROCESSO DE GRADIOMETRIA MAGNéTICA". Um processo e aparelho para detectar campos magnéticos no qual um cordão (1) conduz uma corrente alternada. O deslocamento do cordão de sua posição não perturbada devido a um gradiente magnético através do cordão é detectado por bobinas captoras (L1, L2). Os sinais das bobinas captoras são demodulados usando um sinal derivado da corrente alternada para produzir uma saída.
