Height measurement of axle journals – How can castings be measured reliably and precisely?

Uneven castings are often a challenge when measuring the height of axle journals, as point-based sensors can lead to measurement deviations on rough surfaces. The article shows how a 2D/3D profile sensor with line measurement and integrated evaluation captures the entire surface and thus transmits a stable, highly accurate height measurement directly to the controller.
