CUP200/400 is an automatic measurement system for board cross profile.

The measurement principle of CUP 200/400 is non-contact laser triangulation. Measurement accuracy is, unlike cameras, independent of variations in ambient light conditions and wood surface reflection.

CUP200 is a single sensor system where CUP400 contains two sensors to measure both upper and lower board profiles for increased reliability. The system gives a turning signal if board after drying or cutting is convex and with the convex profile on lower side.
