XR Centreline Thickness Measuring System

XR Traversing Thickness Profile Measuring System (Cold Rolling Mill)

XR Traversing Thickness Profile Measuring System (Cold Rolling Mill)

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

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

One or three ionisation chambers, installed in the upper beam of the c-frame, receive and convert the remaining radiation into electrical signals. Further realtime processing calculates the accurate thickness of the strip.

centreline thickness measurement

optional:
– measurement of thickness cross profile
strip speed / length measurement with integrated strip velocity gauge in the upper beam
