Radar technology relies on intelligent sensor technology based on FMCW microchips, with the wave being generated purely electronically on the chip. This allows non-conductive materials such as plastic to be tested non-destructively and without contact. The speed of the wave in plastic is slower compared to air and can vary between different materials. This difference in speed causes partial reflections of the incoming wave at the material transition. The travel time of these reflected echoes allows the wall thickness of the layer to be determined. In this way, radar sensor technology can be used to determine geometry properties such as wall thickness, pipe diameter and ovality, as well as material properties such as permittivity and carbon black content. iNOEX has reinvented the core of radar, the radar technology itself, with the associated precision electronics and optics, and adapted it to the needs of the plastics market. The radar technology can be used with all common plastics such as PE, L-/HDPE, PP, PA6/-12, PVC, PVDF, etc. without any limitations in measurement accuracy. The measuring accuracy is ±0.05 mm. Since no coupling medium is needed to emit and receive the radar waves, this application is very robust, reliable, and independent of process fluctuations.
