Measure speed and length with laser precision

When producing continuous material (such as strip products) and piece goods in rolling or paper mills, for example, knowing the exact strip length and the current velocity is key if you are to optimize your costs and processes. Non-contact sensors such as the LSV-1000 laser surface velocimeter substantially exceed the performance of conventional contact-based and contactless measurement methods. At the same time, they offer a high level of robustness and reliability in very demanding industrial environments and additionally benefit from minimal maintenance requirements and low maintenance costs.


  • Attractive price / performance ratio and excellent cost-effectiveness
  • All-in-one system, simple process integration
  • Robust sensor technology for reliable operation even under harsh conditions; housing protection classes: IP66 and IP67
  • Reliable material detection (“Material Present” function)
  • Two trigger inputs available for additional light barriers, or optical switches for high-precision edge detection and offset length compensation
  • Fast signal processor with powerful command set for short response times
  • Flexible interface concept
  • Application-optimized accessories such as optional cooling, air purge and thermo-/ protective housing for use in challenging production environments

Compact, reliable, cost-efficient

For reliable processes, controlled velocity and precise cut lengths: make the most of the application advantages offered by laser-based optical length and velocity measurements and, at the same time, benefit from the cost-effectiveness and simple integration as a result of the compact all-in-one design. The LSV-1000 represents Polytec’s latest generation of compact velocimeters for performing non-contact length and velocity measurements on strip products.

This laser length and speed sensor quickly and reliably provides you with length and speed values directly from production processes for control and cut-to-length applications. This allows you to optimize your process, reduce maintenance costs and thus achieve a fast return on the investment you made in your measuring device. Irrespective of whether your measuring task involves performing measurements on steel, shiny aluminum, oily sheet materials, wire, cable or non-metallic materials such as wood, cardboard, building materials and textiles – you can rest assured that the LSV system can take measurements on virtually any surface.
