It is based on a non-contact, transmission measurement principle.
For the determination of the EVOH layer thickness, a wide infrared spectrum of the plastic is recorded and the resulting absorption of the EVOH polymer molecules is evaluated by using our modern analytic methods.

Measuring Principle
XRS is a non-contact measurement system. The x-ray tube emits energy photons. Measurement is based on the absorption of x-ray particles from the source to determine the thickness and basis weight.
This results in greater control of the process whether it’s film extrusion, sheet extrusion and extrusion coating.
