Magnetic Flux Indicator Type II (Castrol strips type A)

5 pcs. of flux indicator strips – Type II (Castro strips type G) with brass finish.

Type I indicators are typically used for general engineering applications and Type II Indicators are used for aerospace applications. Both types consist of three laminations measuring 50 X 12 mm which are fixed together to form a sandwich structure which is nominally 0.15 mm thick. The outer lamination has 3 interruptions which are parallel to the long side. The width of these interruptions and the material of the outer lamination mean’s that Type I indicators respond to a weaker field than Type II strips. Both types are protected by a polymeric layer and can be differentiated by the Roman numeral next to the logo. Flux indicators have the advantage of being flexible enough so that they can be bent to fit the contours of a work piece, but robust enough to enable them to be used many times. They may also be cut into smaller pieces to allow them to be fixed in recesses and otherwise inaccessible locations on the work piece.
