Abstract
In this paper, a magnetic non-destructive system was constructed to detect surface cracks on a ferromagnetic materials. An analog-dijital converter interface board has been designed for a magnetic non-destructive system, to collect data by using a personel computer. The electronic circuit and operating principles of board will be given in detail.

Abstract
Bu çalışmada ferromanyetik malzemelerde herhangi bir sebeple oluşan çatlakların belirlenebilmesi için, üç boyutta hareket edebilen bilgisayar kontrollü 3D tarayıcı sistem geliştirilmiştir. Sistemin değişik bölgelerine üç farklı değişkeni ölçen algılayıcılar yerleştirilmiştir. Bu algılayıcılardan gelen analog veriler değişik elektronik kartlardan geçerek bilgisayarın paralel portuna verilmiş Visual Basic’te yazılan programla bir text dosyasına aktarılmıştır. Bu makalede 3D tarayıcı sistemde üç farklı algılayıcıdan gelen analog verilerin bilgisayara aktarımının nasıl yapıldığı ayrıntılı olarak tartışılmıştır.
