Polytec Compact Velocimeters – LSV 1000 Laser Surface Velocimeter



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.
