Automated Tile Flatness Inspection Using Laser Displacement Sensors

Industry pain points and demands

In tile manufacturing, flatness directly affects installation quality and visual appearance. Even small bends or surface unevenness can lead to rejection after delivery. Manufacturers need a stable inspection method that works at production speed, avoids surface damage, and delivers consistent results for quality control.

SinceVision Solution: SD33-50 Laser Displacement Sensor

01Non Contact Inline Measurement: The SD33-50 laser displacement sensor performs non contact flatness inspection, preventing surface wear while supporting fixed installation on the production line.
02High Measurement Accuracy: With 5 µm repeatability and up to 0.02 mm inspection accuracy, the sensor reliably detects tile warping, bending, and uneven surfaces.
03Stable Performance in Continuous Production: With a 50 mm reference distance, ±10 mm measurement range, and ±0.1 percent full scale linearity, the system delivers consistent and reliable results during ongoing production.
