Industrial Length & Speed Control

  
Precision speed and length measurements are critical for optimization of production processes such as those used in rolling and paper mills. Proper utilization of these measurements can lead to lower production costs and higher product quality. Polytec velocimeters are a better choice than traditional contact wheel encoders for today's mill environment, providing better precision, lower maintenance costs, fast return on investment (ROI) and plug-in compatibility. More than 1000 Polytec Laser Surface Velocimeters (LSV) are installed worldwide and routinely measure speed and length of moving surfaces with extreme laser precision and without contact on coils, strips, tubes, fiber, film, paper, foil, composite lumber, or almost any other moving material, including hot steel. The best testament to our products' performance is our customers and their numerous successful LSV applications.
