High-sensitivity tramp metal detector

Tramp metal detector

Thermo Scientific Ramsey Oretronic IV tramp metal detector is designed to minimize lost production time

BELT conveyor operators can now install a new, highly sensitive tramp metal detector designed to optimize production time, protect process equipment and reduce false alarm rates.

The Thermo Scientific Ramsey Oretronic IV tramp metal detector builds upon the existing line of tramp metal detectors by increasing sensitivity for improved detection capabilities.


Thermo Fisher designed the new device to better detect all types of metallic scrap, including bucket teeth, manganese steel mantles, bore crowns, bar scrap, chains and tools. The increased sensitivity of the Oretronic IV detector allows it to identify tramp metal buried in wet, conductive materials quickly and accurately.

‘Protecting expensive conveyors, crushers and other process equipment from damage is vital for owners of processing and manufacturing plants to avoid costly operational downtime,’ said Paula Frisk, product manager for bulk weighing and monitoring solutions with Thermo Fisher Scientific.

‘With increased sensitivity in this newest tramp metal detector, manufacturers can feel even more confident that damaging scrap metal will be found before it causes equipment failure and profit loss.’

The Oretronic IV tramp metal detector, 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.

Additional features of the Oretronic IV tramp metal detector include: variable frequency, designed to allow the operator to adjust the frequency to eliminate interference and false alarms from motors, radios and other external devices; a fiberglass support structure for the coils that is resistant to moisture; advanced electronics with an LCD display, touch-button keypad and new menu for easy set-up, calibration and system use; and simple installation/ease of upgrade from existing instruments in the Oretronic tramp metal detector line.
