Radar solution for measuring the thickness of slabs, flat and long steel – with sub-millimeter precision.
The precise thickness measurement of metal products is essential to achieve reliable product quality at all times in rolling mills and continuous casting plants. Our radar sensor solution determines the thickness and the thickness profile of steel plates, steel strips or steel slabs (up to 1600 °C hot) with an accuracy of up to ±10 µm on the roller conveyor. Thanks to robust radar technology, sophisticated signal processing and intelligent radar algorithms, OndoSense radar sensors achieve this high level of precision in thickness measurement even under the difficult production conditions of the steel industry with smoke, steam, dirt, vibrations, fire and extreme temperatures. Good to know: Material thickness, alloy, metal type (e.g. aluminum, copper, steel, etc.) and metal properties have no influence on the accuracy of the thickness measurement.
This makes the OndoSense radar sensor solution an attractive alternative to radiometric thickness measurement of semi-finished steel products: These measuring systems based on radioactive isotope or X-ray emitters are expensive - both in procurement and in operation. They also require complex radiation protection and intensive maintenance.
