The Ramsey Oretronic IV tramp metal detector has increased sensitivity for improved detection capabilities. It is designed to work with belt conveyors that move minerals, iron pellets, coal, aggregates and other bulk materials to better detect all types of metallic scrap, including bucket teeth, manganese steel mantles, bore crowns, bar scrap, chains and tools. The increased sensitivity allows it to identify tramp metal buried in wet conductive materials quickly and accurately. The Oretronic IV, which is available in two versions with two levels of sensitivity, includes a microprocessor-based control unit, a receiver coil, a transmitter coil and a support frame.
