Speed and Length sensors
Polytec Laser Surface Velocimeters (LSV) measure speed and length of moving surfaces accurately and without contact on coils, strips, tubes, fiber, film, paper, foil, composite lumber and almost any other moving material, 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 through its digital or analog interfaces.
Don't take chances. Call us to benefit from Polytec's long experience in laser-based speed and length measurements.
