Laser doppler velocimetry (LDV) has been a long-proven method for accurately measuring the length and speed of products. But many applications involving the production of long, continuous cylindrical products pose measurement challenges. Products that cannot be well guided, move off-axis and move out of the measurement range make it difficult for traditional LDV-based gauges to keep the laser on the product’s surface. This results in hard-to-obtain and unreliable length and speed measurements. Cylindrical products that are small and/or have a severe curvature compound this measurement issue. This new patent-pending LDV technology is a breakthrough development for hot rolling long products.
