DXD and DXD+ Dual Energy Detector Technology

Oct. 4, 2022
Mettler-Toledo's DXD and DXD+ technology provides detection of ‘hard-to-find’ contaminants.

The DXD and DXD+ dual energy detector technology is optimized for identifying foreign bodies such as calcified bone, low-mineral glass, rubber, and some plastics. The technology improves the ability to detect low density contaminants in packaged food products; it can help food manufacturers avoid product recalls, reduce unnecessary product waste costs, and enhance product integrity.


The ideal types of contaminants for this technology are traditionally hard to detect within the ‘cluttered’ or ‘noisy’ x-ray images generated by overlapping and multi-textured products such as packs of pasta, chicken breasts, sausages, and frozen potato-based goods. Such applications are a perfect match for DXD and DXD+ high-quality detector technology, in conjunction with Mettler-Toledo Advanced Material Discrimination software tools. The software helps to separate and remove the prominent material of the food product within the x-ray image, revealing the presence of any lower density contaminants.

  • DXD: high-quality x-ray performance at an affordable price; can operate in the same environments as single energy solutions and can be used with line speeds typically up to 100 m/minute
  • DXD+: reliable detector technology for the most challenging applications; collects more data about the product being inspected, and improved image analysis software provides clearer images with higher resolution; DXD+ can be used with line speeds typically up to 45 m/minute
