Polytec Laser Surface Velocimeters (LSV) measure speed and length of moving surfaces accurately and without contact.
LSV's measure accurately on coils, strips, tubes, fiber, film, paper, foil, composite lumber, and almost any other moving materials, including hot steel.
Polytec's LSV systems are designed to perform continuously in harsh environments. The LSV control processor is easily interfaced with your process by its digital or analog interfaces.
