Width Measurement of Steel Strips via 2D/3D Profile Sensors

When manufacturing strip steel, the exact width of the strip must be ensured. If the strip is too narrow, the edges will not touch and there will be no welding seam. If the strip is too wide, the material will be compressed too much. To carry out this measurement with micrometer accuracy, several 2D/3D profile sensors are installed in a line above the steel strip. There, they measure the glossy strip with measuring frequencies of up to 6,000 Hz. If a tolerance value is exceeded, the strip stops immediately. Vibrations and ambient light have no influence on the accuracy of the measured data.

MLWL 2D/3D Profile Sensors

2D/3D profile sensors from the weCat3D series use the principle of laser triangulation to create 2D height profiles and 3D point clouds. The MLWL model offers unbeatable profile quality thanks to its optimized, high-quality optics.
