Abstract

Uklad zawiera zintegrowana glowice pomiarowa z impulsowym wzbudnikiem (1) zmiennego pola magnetycznego i detektorem (2) pola rozproszenia, blok przetwarzania (6), analizator sygnalów (7) oraz nosnik pamieci (8). Wzbudnik (1) i detektor (2) usytuowane sa ponad powierzchnia ciegna (3), rozstawione wzdluz linek (4) oraz w kierunku ruchu (V) kolejno w bezposrednio bliskiej odleglosci (?L).The system includes an integrated measuring head with a pulsed inductor (1) of a variable magnetic field and a detector (2) of a scattering field, a processing block (6), a signal analyzer (7) and a memory carrier (8). The inductor (1) and detector (2) are located above the string surface (3), spaced along the lines (4) and in the direction of motion (V) successively in a close distance (? L).
