Laser Surface Velocimeters

Position tracking on sheet materials and piece goods

Position tracking plays an important role in the paper industry if a certain position on the object being measured is essential to the process. Length measurement can trigger a working step at regular intervals in the process, e.g. printing labels or attaching lettering and logos. The LSV instruments from ZUMBACH are ideally suited because they can conduct measurements on almost any surface and they are not susceptible to contaminated surfaces. The non-contact measuring technique makes it possible to eliminate any negative influences on accuracy, such as slippage and wear, simultaneously. The product being subjected to the measurement remains intact too. The increased accuracy of velocity and length measurement allows to determine positions with more precision. As a result better adhesion to the end product requirements is achievable. The result: Increasing the quality while at the same time reducing waste.

Reliable measuring on almost any solid surface:

  • Carbon steel
  • Shiny aluminum
  • Oily sheets
  • Wire and cable
  • Paper, cardboard, tissue
