Measure Surfaces with Nanometer Precision

Polytec laser surface velocimeters, known as LSVs for short, provide you with support when you’re monitoring continuous material and piece goods in the production process. They can be integrated in a very flexible way, are convenient to set up and yet are extremely easy to use and dependable in operation. It doesn’t matter whether you’re producing belts, pipes or profiles with a shiny or a matt surface – a Polytec LSV adapts to any task and measures the surface velocity and cut lengths of the items with zero contact and from a safe distance.

The LSV product line includes compact sensors, modular systems and models certified according to MID.

Compact yet Uncompromising

Polytec’s compact velocimeters allow you to contactlessly measure both the length and the velocity of continuous material and piece goods. The measuring device quickly and reliably provides you with length and velocity values for inspection and cut-to-length applications with the precision that can only be achieved through using a laser. The resulting reduced maintenance costs and increased output mean that you will see a fast return on the investment you made in your measuring device. Irrespective of whether your task at hand involves performing measurements on steel, shiny aluminum, oily sheet material, wire, cable or non-metallic materials such as wood, cardboard, building materials and textiles – you can rest assured that the LSV can take measurements on virtually any surface.
