Proven over many years, the Ramsey tramp
metal detector gives a high accuracy and sensitivity that will detect all sizes
of ferrous and non ferrous metals. The unit can be set up in minutes and gives
reliable and repeatable results. A NEW detector will be available later this
year with even more features. Please contact us for full details of this new
Tramp metal can stop your operation, and the damage it causes to equipment can be expensive. The Thermo Scientific Ramsey Oretronic III tramp metal detector provides an economical and reliable means to protect expensive crusher, conveyors and other process equipment from damage by tramp metal. The Ramsey Oretronic III tramp metal detector is designed especially 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 and tools. It can even detect tramp metal when buried in wet conductive materials. And, because it is insensitive to materials with high magnetic permeability and electrical conductivity, this tramp metal detector can be used in applications where conventional metal detectors produce an unacceptable false alarm rate.

It has a microprocessor-based control unit that automates system setup and calibration. The operator interface provides easy-to-read indicators and has a touch panel keypad designed to simplify setup and system maintenance. This tramp metal detector also features variable frequency to eliminate interference from other electrical equipment, password protection for security, and RS-485 serial communications.
The system’s coils are made of impact resistant polyvinyl chloride and designed to withstand stresses of up to ten times the force of gravity. The generator coil and dual wound receiver coils mount on a support made of non-conductive materials. The field generator coil is swing-mounted to protect the coil and support from being struck from oversized materials. A dual receiver coil is employed to counteract interference from external sources, such as electric motors, lightning and radio transmitters.

Microprocessor-Based: No adjustments are necessary inside the enclosure.
All functions can be accessed from the front panel.
Variable Frequency: You may set the operating frequency.
Interference and false trips from motors, radios and other external devices are eliminated.
Quick Balance: This allows you to electronically balance the coil with the push of a key.
New Coil Frame: Coils are made of impact-resistant PVC and mounted on a fibre glass support structure. The coils and entire support structure are impervious to moisture.
Offset Swing Arm: This protects the coils and reduces the likelihood that they will break due to high burden.
Simple Installation: The detector can be installed without cutting the belt and without utilizing special tools or instruments.
Serial Communications: RS-485 is a standard feature incorporated to permit communication between the metal detector and a remote front panel or PLC.
Password Protection: Create a PIN to prevent unwanted access to the detector’s controls.
Single Coil (optional): The combination of the generator and receiver coils into a single, under-the-belt coil assembly eliminates damage from high burden depths and interference from overhead metal objects.
