Reading the DOT code on tires

When manufacturing automobiles for the American market, the DOT numbers of the tires must be stored. Vision systems are not suitable for reading the code, due to the poor contrast involved (black letters on a black background). The scanCONTROL 2750-100 measures the distance from the surface with the aid of triangulation. The sensor transmits a height profile of the tire wall directly to the software application.
