KMU 8/42 CROSS YOKE

Specifications

     The KMU 8/42 Cross Yoke represents a supplement to the HANSA series – the new generation of hand yoke magnetizing devices. The KMU 8/42 consists of two alternating current yokes disposed crosswise with pole spacing of 170 mm. They are fed by 2 equipotent alternating currents with 90° phase shift, thus producing a rotating magnetization vector whose field strength is equal in all directions. This magnetization technique enables the detection of discontinuities of any orientation. In practice it enables: simultaneous indication of longitudinal, transversal and oblique cracks during one operation. Therefore, the KMU 8/42 Cross Yoke is especially appropriate for testing of lengthy welded joints, for example in pipe manufacturing, tank and pressure vessel building or ship building.

The long-duration duty cycle of up to 60 % favourises the application in these production fields. The magnetic field is induced to the part under test over a short air gap. Therefore the yoke poles are equipped with adjustable castors. The castors maintain a constant air gap between the poles and the part surface and make the yoke easily movable. The KMU 8/42 Cross Yoke is completely sealed, powered by an additional transformer with 2 x 42 V alternating voltage and fulfills the IP 54 protection class requirements. The cross yoke and the transformer are coupled with a flexible 5 m cable. The transformer meets the criteria of the IP 23 protection class and requires the primary voltage of 3 x 400 V.
