Three laser triangulation displacement sensors measure the deflection of ceramic wall tiles during production with an accuracy of 0.1 μm to inspect for flatness. The sensors can specify separate acceptable values for concave or convex deflections. The laser-based optical displacement sensors are mounted in the production environment and interfaced with a microcomputer system to acquire measurements and check tiles against quality standards.

Flatness inspection on ceramic wall tiles
In the production of ceramic wall tiles or similar Technical details
products, a one hundred percent quality inspection - Measuring range 20 mm
is essential. Three laser triangulation displacement - Reference distance 50 mm
sensors measure the deflection of tiles with an - Accuracy ± 0.1 mm
accuracy of 0.1 µm. Separate specification values - Fast adaptation to varying surface conditions
can be entered for concave or convex deflections.
Ambient conditions
- Production envirmonment
- Temperature range + 10 to 35 °C dust
