Soft X-Ray System

XRS is low energy x-ray gauging system (< 5kVA) that measures thickness and basis weight of thin films such as cast films, non-woven and other flexible packaging.

Due to low output voltage, XRS does not require licensing in most countries leading to easy installation and maintenance.

Ultra-precise thickness measuring with an accuracy of ≤ 0,2 µm

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.
