Measuring System
The XR triple-head thickness profile measuring system measures strip thickness and the thickness profile continuously and in real time.
The upper beam of the C-frame of the triple-head thickness profile measurement contains a task-based number of ionisation chambers to receive the radiation from the x-ray tubes installed in the lower beam. The ionisation chambers convert the thickness-dependent quantity of x-rays that pass through the material into electrical signals, which are then used to calculate the exact thickness of the material.
The centre measuring head of the system supplies the data for control (AGC) of the mill stand. The traversing outer measuring heads determine the thickness at the edges of the material for calculation of the important wedge and crown values.
continuous thickness measurement in the centre of the roller table
continuous measurement of the strip thickness profile by counter or synchronous traverse of the edge mea-suring heads
measurement of width and centreline deviation
calculation of wedge and crown values
faster cross-profile acquisition compared to an XR Twinset measuring system
permanent guarantee of centreline thickness measu-rement with the option to select the measuring head at will

…These are particularly impressive due to their long service life and constant performance.
Our measuring systems allow our customers to always be one step ahead of the competition.
Our motto of “Precision out of passion and quality out of conviction” is the decisive criterion for the development of our high-precision measuring systems, many of which have been and still are world firsts.
To be allowed to actively support this pioneering spirit for more than 30 years, as well as our passion for precision, is a challenge anew for me every day, which continues to motivate and inspire me even after all these years.
For me, it’s not enough to just talk about the matter. You have to speak to the people and therefore it is my personal goal to guide you through the buying process with the quality of my advice and my support, to develop with you exactly the measuring system that is right for your specific measurement tasks and that has been specially tailored to your individual application.”
