Scanning Hot Metal Detector


Rota-Sonde DC2000


  • Easy alignment of the sensor.
  • Assured detection regardless of the transverse position of the product.
  • Precise detection thanks to the narrow lateral field.
  • Reliable detection because of the small analysing beam.
  • Photosensitive cell that best suits application in rolling mills, despite scale and steam.
  • Very low maintenance, virtually nil in some cases.


The Rota-Sonde DC2000 is a scanning sensor, which is sensitive to the infrared radiation emitted by hot products.

It is a self-contained detector including :

  • An optoelectronic case with a protecting hood of the viewing port and a connector.
  • A cooling plate with an adjustable mounting stand.

Because of its design and particularly its cast aluminium case, the Rota-Sonde DC2000 is specially adapted for the harsh environment of the Steel Industry (vibrations, heat, vapour and dust).

Operating principle

The detection field is scanned by a rotating polygonal mirror which reflects the infrared radiation from the product to the photocell
