Innovative length measuring system

The technology of the LENGTH 6000 is based on an optical measuring method. Thereby, the picture of the surface is projected on an image sensor. Speed and length are precisely calculated by means of the movement of the image pattern. The system detects whether the product moves forwards or backwards and takes this information into account for the length measurement.
Conventional length measuring devices using the principle of frequency shift show weaknesses for length measurement of profiles with round or blank surfaces. Mechanical systems, on the other hand, provide only limited precision due to the slip on the product surface.

Significant cost savings
The use of length measuring devices for the production of extruded products contributes to extreme cost savings. Assuming an extrusion line produces products amounting to approximately 30 million €/ year. If the delivery length is reduced by as little as 0.1 %, 30,000 € can be saved and the LENGTH 6000 is amortized in very quickly.

 

Your Benefits

  • Highest reliability and precision for all product colors and surfaces
  • No adjustment at product change
  • Length measurement independent of whether the product is moving forward or backward
