Tunnel metal detector heads are designed for installation on conveyor belts. They are used particularly often during the modernization of existing installations to meet the standards applicable to the given products. For this purpose, they are designed in a way that allows for trouble-free connection with already functioning and new automation systems, as well as with a computer network, enabling keeping production statistics.
As a basic component of metal detection systems as well as devices offered together with transfer and rejection mechanisms, tunnel heads have the same computer-based learning algorithms for good and defective products, with the possibility of saving them for reuse. Tunnel heads can also function in tandem with visual inspection performed by employees as a verification means facilitating correct inspection.
