Hot & cold magnetic detector family

no next

The MD2000 series is the ideal solution for metal detection in harsh environments where infrared detection is not reliable due to vibrations, water or steam presence. This detector family finds metal presence by means of a magnetic field.

The measurement principle is based on eddy currents generated on the surface of a bar by a variable magnetic field. An excitation coil induces eddy currents in the bar. The reaction field produced by the eddy currents is detected and converted into electrical signals by a receiving coil. A digital output is activated by the presence of a bar inside the detection ring-head. An embedded micro-controller checks the system state and dynamically sets sensitivity levels to guarantee optimal performance. A number of different models cover a wide range of applications, to be chosen accordingly to the dimensions of the material to be detected. Moreover, fast running wires can also be reliably detected. The high quality and reliability inherent in DANIELI AUTOMATION detectors gives our customers the benefit of a 3-year warrantee period.
