Film Thickness Measurement
on web coating machines


The film thickness profiles of web produced or coated foils can be determined in cross- and/or machine-direction by using a scanning bridge and our TranSpec-DSP film thickness gauges. This permits an intermediate feedback for your process and production control.

The following picture shows the schematic gauge setup for film thickness measurement on a web coating or foil machine. The actual sensor (the fiber optics light guide) is mounted on a linear motion bridge and continuously moved forwards and backwards in cross-direction to the coating machine:
