Non-retractable Gauge (Foil Mill)
XR Centreline Thickness Measuring System
XR Centreline Thickness Measuring System
By means of continuous, non-contact, real-time measurement, the XR thickness measuring 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.
centreline thickness measurement
optional:
- fixed mounted non-retractable C-frame
- swivel mechanism for the detector head
Special Features
- customised design and software

#IMS Expert
Christian Knackstedt,
Dipl. Engineer
…for you as a specialist for cold rolling mills. One part of your solution here is offered by our innovative and high-precision measuring systems for the cold strip sector, which have proven that they measure and detect lastingly and reliably even under the most adverse environmental conditions.
How challenging and different such environmental conditions as well as the tasks assigned to you as the responsible person can be is something I am well aware of, not only theoretically but also practically, from more than 20 years of working for IMS. I started out as a systems engineer in the field of software and commissioning. Today, in the position of Global Sales Manager, I am your IMS expert for measuring systems in the cold strip sector.
Making measurable what can be measured is part of our corporate philosophy. The “how” in your particular case is as much my challenge from the moment you contact me as it is yours. My personal benchmark is your constant high product quality and – especially – your equally constant trust out of conviction in the performance of our measuring systems.”
