The Metcorr 117C industrial metal detector is able to detect both ferrous and non-ferrous metals over a wide spectrum of applications from magnetite mines to wood chip conveyors. The dual sensing technique employed by the Metcorr 117C ensures a uniform response from rod- or bar-shaped objects irrespective of their orientation. The Metcorr 117C can also be used on conveyors with steel corded belts.
