Multiple Width System

Non-contact width measurement of large objects

MWS, Multiple Width System, is a non-contact measuring system for width measurement of one or more tracks in e.g. paper machine, cutting machine, rolling mill etc. The system measures width of non transparent materials by using cameras and background lighting. Every edge is detected by a camera mounted on a mobile rail above the measuring object. The rail follows so the camera is always straight above the measuring objects edge.

Characteristic
  • Non-contact measuring with very high accuracy
  • Large measuring range
  • Insensitive against vibrations and temperature variations
  • Modular and rough construction designed for industrial applications
  • Fast measurements, 5 measurement per second
  • Reliable system managing to measure round the clock, year after year without interruption
  • Custom-made construction

Advantages
  • The camera gives high accuracy on a small measuring range.
  • The camera is always above the measuring objects edge, which eliminates parallax error.
  • Because the cameras are mounted so near the track (4 - 20cm), the system will not be affected by vibrations and temperature tensions.
  • The system can be equipped with extra beams if necessary.
  • Latronix develops and manufactures the whole system under the same roof; therefore we have the possibilities to adjust it according to the customer's specifications and requirements.

Measuring method

The system measures width of non transparent materials by using cameras and background lighting of the material. The cameras are detecting the edges of the dark material against the light background illumination. Every edge is detected by a camera mounted on a mobile rail above the measuring object. The rail follows so the camera is always straight above the measuring objects edge.
