The mode of operation of the Yoke is based on electromagnetic principle: when a coil (or solenoid) is crossed by electricity, a magnetic field is generated. The coils are wrapped on a laminated magnetic nucleus, which forms the body of the yoke. The magnetic core is provided with “contacts” having a possibility to be orientated on the inspection surface thanks to specific junctions. Feeding the coils of the yoke, the generated magnetic field generates two opposite polarities on the extremities of the nucleus which produce a magnetic field flux on the area to be checked.

Leaning these expansions on the part under inspection and activating simultaneously the “Yoke” and the application of the magnetic powder (wet or dry), it is possible to highlight cracks having orthogonal direction +/- 45° with reference to the direction of the magnetic field between expansions. It’s relevant to underline that at the same conditions the current passes through the piece, the magnetic field intensity is inversely proportional to the distance between the expansions on board the yoke and the surface

CGM CIGIEMME S.P.A. produces and supplies the full range of yokes: permanent magnets, 220 V, 48 V, in AC and/or DC. In addition, a battery powered version is available.

Lightweight, manageable, CE marked, realized in accordance with the rules in force.
