Thickness measurement - Import export

Thickness measurement on plastic film samples requires automatic transport of the film strips through the measuring device, allowing for the flexibility of the material being measured. The desktop version of the VDM measuring station can be equipped not only with the pure measuring device, but also with PC-aided evaluation and graphic representation of the measurement results.

Many materials cannot be measured tactilely, therefore non-contact thickness measurements become necessary. Especially e.g. with glowing materials, or wet processes, a continuous tactile measurement is nearly impossible. Furthermore, web speeds in plant engineering and production have increased, requiring a corresponding fast sampling rate of the measuring systems. In addition, high measuring widths are often required. Why is contact free measurement technology so perfect for this application?
