Features and Benefits

The Oretroni Oretronicc II IIII iiss de signe d es pec ially ially for belt conveyors moving coal, iron pellets, minerals, aggregates and other bulk materials. It can detect all types of metallic scrap including: bucket teeth, manganese steel mantles, bore crowns, bar scrap chains, tools, etc. It can even detect tramp metal when b ur uriied in we t co nductiv nductivee materials. And, because it is insensitive to materials with high magnetic permeability and electri electrica ca l cond uctivity, uctivity, the Oretr Oretronic onic II IIII can be used in applications where conven-
