Non-contact measurement of speed and length for production control
In the production of strip and sheet material, continuous material as well as piece goods, for example in steel or paper mills, knowing the exact strip length and current process speed is essential for keeping costs low and optimizing quality and yield. LSV (Laser Surface Velocimeters) from Polytec are optical sensors for the precise in-line monitoring of length and speed in production processes. The laser sensors measure in a non-contact way, providing precicion measurements on any material - no contact, no slippage, no wear. Avoiding any influence on the measured material, these non-contact encoders works reliably even in harsh production environments, in cold and hot temperatures. The latest generation ProSpeed® LSV length and speed sensors impress with maximum precision and reliability, featuring a 3-year warranty and custom service options tailored to your process control.

Enhancing industrial processes with optical sensors
Efficient process control using ProSpeed® laser speed and length sensors
Climate change is one of the dominating challenges of modern society and industry. Even though steel is one of the worlds most recycled materials, the steel industry remains the largest industrial emitter of carbon dioxide. For a more sustainability and responsible manufacturing, ProSpeed® Laser Surface Velocimeters can assist in process control
Mass flow control
Skin-pass degree, roll gap control or strip thickness measurement: Controlling the mass flow process means controlling the width of the roll gap so that the material thickness of the final product remains as constant as possible. ProSpeed® LSV laser-optical sensors help determine the thickness before the roll stand as well as the velocity before and after the roll stand, providing reliable inline measurement data for precise adjustments during the production process.
Continuous casting
High temperature resistance and repeatability are key for continuous casting lines. ProSpeed® LSV optical sensors enable reliable production process control, directly increasing the casting yield. Reducing the safety factor by just a few mm when cutting to length, the investment cost for optical sensors in casting lines amortize within ~one year. For hot and harsh conditions, the TPH Thermo-Protective Housing keeps a cool (sensor) head, with excellent cooling capacity up to 200 °C.
