Micro-Epsilon's thicknessControl MTS 820x and MTS 920x thickness measurement systems offer an innovative and efficient solution for measurement tasks in hot rolling mills. According to the manufacturer, their highly precise measurements on thick and thin materials make them even more accurate and economical than X-ray equipment.
The thickness of the material decreasing during the rolling process must be monitored regularly. The measurement technology used has to meet high demands, as not only thick but also thin materials have to be measured with consistent accuracy. Until now, this application could only be solved using X-ray equipment. In addition to the high acquisition and operating costs, there are other disadvantages to consider. If alloys are changed, they have to be recalibrated and lose accuracy as a function of material thickness.
Micro-Epsilon thicknessControl MTS 820x and MTS 920x high-precision thickness measuring systems offer a new, efficient application solution. Their innovative technology enables extremely precise measurements on thick and thin materials. What's more, they are insensitive to the harsh industrial environment that exposes them to steam heat during emulsion application. Sensors equipped with a cooling system enable temperature-stable measurements. Hot surfaces also require large measurement ranges, so that sensors can be placed at a safe distance from the object.
Thickness measurement systems work with special laser line scanners. These are integrated into the upper carriers of the O and C frames, and feature two sequential measuring ranges. The measuring range is divided into two parts by two optics and two matrices in the scanner. This enables the thickness gauges to operate in different accuracy ranges. With a material thickness of 400 mm, a 10-fold improvement in accuracy over conventional X-ray equipment is achieved. Unlike X-ray equipment, there's no need to recalibrate when changing alloys.
