FOERSTER has developed the multi-channel rotating heads Ro 40 F

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.

Your advantages at a glance

  • Max. throughput speed 6 m/s (Ro 20 F) Sensitive detection of longitudinal surface defects starting from a depth of approx. 30 μm
  •  Sensor system consisting of four sensors offset by 90°
  • For testing ferromagnetic, austenitic and nonferromagnetic round material (tubes, rods, wires)
  • Test heads available with 1.5 mm / 2.5 mm / 5 mm track width (analogous to sensor system Ro 20 P)
  • Modular design enables easy replacement in existing lines
