XR Centreline Thickness Gauging System

Non-retractable Gauge (Foil Mill)

Non-retractable Gauge (Foil Mill)

By means of continuous, non-contact, real-time measurement, the x-ray thickness gauging system measures the centreline thickness of the foil.

With this measuring method, the material is radiated by a single x-ray source, mounted in the lower housing of the gauge.

One or three ionisation chambers, installed in the upper housing of the gauge, receive and convert the remaining radiation into electrical signals. Further realtime processing calculates the accurate thickness of the foil.
