Using the latest image processing techniques, the ColObserver® performs an accurate acquisition and highly sophisticated image treatment to measure the colour of products in real time. Installed above a conveyor, the on-line colorimeter equally controls the colour of big stones at the quarry and smaller ones—down to powders, at the plant. The camera not only measures the colour in real time but also detects, sorts and counts non conformities. The stones can be sorted in various stock piles according to their colour for future blending. Alarms can be set up to divert the off-spec products i.e clay or any coloured stone, avoiding any contamination. At the plant, the ColObserver® manages the blending of various sources to stabilize the inlet feeding. In control room, the system displays the calculated data, the colour trends as well as the video of the on-going production. It records video sequences on events for full traceability and further analysis of the process.

Maintenance can be performed remotely by ITECA engineers using the available customer Internet access, with secure screen sharing software.
