NOME STRUMENTO<\/strong><\/p>\n

Gradiometro fluxgate Bartington 601<\/p>\n

 <\/p>\n

INFORMAZIONI GENERALI<\/strong><\/p>\n

Lo strumento gradiometro disponibile nel MOLAB \u00e8 utilizzato per le indagini in situ essendo estremamente maneggevole, veloce e completamente non invasivo. Lo scopo di un rilievo di tipo magnetico \u00e8 quello di investigare la struttura del sottosuolo sulla base delle anomalie del campo magnetico terrestre prodotte dalle differenti propriet\u00e0 magnetiche dei materiali presenti nel sottosuolo. Il campo magnetico che si pu\u00f2 misurare sulla superficie terrestre varia in modo sensibile in funzione dello spazio e del tempo. Vengono quindi misurati valori numerici riferiti ad una precisa coordinata spaziale. Senza tale riferimento, un gruppo di valori non ha alcun significato. Lo strumento viene normalmente spostato lungo linee di misura equidistanti, note come traverse, separate da una distanza fissa, \u0394y. Il dato viene acquisito sopra tali traverse a specifici intervalli di campionamento, \u0394x. Si definisce gradiometro uno strumento mediante il quale si campiona il valore del gradiente del campo magnetico, dB\/dz. Il gradiometro non \u00e8 altro che un magnetometro differenziale, ovvero \u00e8 dotato di due sensori separati da una distanza fissa e piccola rispetto alla distanza delle sorgente di cui si vuole misurare il gradiente. Per operare in questa configurazione i due sensori devono procedere al campionamento di B simultaneamente.<\/p>\n

DETTAGLI TECNICI<\/strong><\/p>\n

Lo strumento gradiometro fluxgate portatile \u00e8 il Bartington 601 dotato di 4 sensori fluxgate che consentono di acquisire il gradiente magnetico contemporaneamente su due linee distanziate di un metro.<\/p>\n
