Optical measurement of drive shaft, brake disc and wheel tires

Tread surfaces of wheel tires are exposed to enormous loads. In order to determine the overall condition, to detect defects and to take timely repair measures, the wheel discs must be inspected regularly. The wheel sets are first tested in measuring machines with optical sensors from Micro-Epsilon. 

The rotating wheelset is measured with laser distance sensors, which determine the axial and radial runout. Laser profile scanners also detect the complete profile at selected measuring points.
