Circograph Rotating Heads for Fast Applications

Contactless eddy current testing of bright steel

High Throughput Speed for Higher Productivity

Applications such as the rewinding of tubes in copper tube production or wire drawing require a rotating sensor system that can cope with the high throughput speed. The rotating heads Ro 20 F and Ro 40 F were specially developed for such applications. The powerful, multi-channel rotating heads are designed for tubes, rods and wires with a material diameter of 2 – 40 mm. They allow for sensitive detection of longitudinal defects in the material surface. Defects starting with a depth of approx. 30 μm can be displayed in their full length and with high resolution.
