With the iXRAY, we can achieve reproducibility and quality assurance in the µm range. The 3-axis system can also guarantee accurate measurement of ovality. Arno Neumeister Product Manager X-Ray
THE MEASURING PRINCIPLE
A very narrow, fanned X-ray beam is generated in the encapsulated X-ray tube, which hits a scintillation layer on the detector. The X-rays are absorbed in this scintillation layer and converted into visible light. The underlying photosensitive chip detects the intensity of the visible light.
Is there a pipe or cable to be measured placed in the beam path, the X-ray radiation is partially absorbed by the measurement object. Due to these changes in the absorption, we can measure wall/layer thickness distribution, interior and exterior diameters, ovalness and eccentricity.
THE 3-AXIS SYSTEM
The pipes and hoses produced in the extrusion process are not perfectly round, but usually have an elliptical shape. In addition to wall thickness, outer and inner diameter, the ovality and eccentricity are of particular importance for the pipe, hose and cable producer. To be able to determine ovality and eccentricity with suffi cient accuracy, X-ray systems with 3 measuring axis should be used.
A 2-axis measurement system only has limited suffi cient measured values. Because oval tubes and perfectly round tubes can have the same wall thickness measurement on two axis. In contrast to that a 3-axis system can provide an accurate measurement of ovality.
