Abstract :
Magnetic contactless speed measurement sensor targets steel industry. Controlling any production line requires the use of many sensors along the line. A basic measurement in steel lines is the determination of the exact linear speed of some portions of the process. This article comments on the complete speed measurement system for steel lines, with a cost lower than US$300, a range up to 800 m/min, and accuracy of about 0.4%. Accuracy is influenced by the position of the sensors.
