XR Centreline Thickness Measuring System

XR Traversing Thickness Profile Measuring System

XR Traversing Thickness Profile Measuring System

The XR centreline thickness measuring system detects material thickness in the centre of strip by means of continuous, non-contact, real-time measurement. The C-frame for the XR centreline thickness measurement

can optionally be designed as a traversing measuring system and thus measure the thickness cross profile.

With this measuring method, a single x-ray source mounted in the lower beam of the C-frame is used to focus radiation on the measurement area.

The upper beam of the C-frame contains a task-based number of ionisation chambers that convert the radiation that has passed through the material into electrical signals, which are then used to calculate and record the exact thickness of the material.

centreline thickness measurements (also available as non-retractable gauge)

optional:
– measurement of thickness cross profile
– integrated temperature measurement
