Position tracking plays an important role in the wood and construction materials industry if a certain position on the object being measured is essential to the process. A laser surface velocimeter (LSV) measures the length that the object being measured covers until a defined event occurs. The length measured is then used to correlate the event to the corresponding position on the object. One example of this is flaw site detection in non-destructive materials testing. The Length measurement can also trigger a working step at regular intervals in the process, e.g. printing labels, attaching lettering and logos or marking flaw sites.
LSVs from Polytec 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 you to determine positions with increased precision. As a result you are better able to adhere to the end product requirements. The result: You increase quality while at the same time reducing waste.
Polytec LSVs are used for various position detection tasks in the wood and construction materials industry.
