Precise speed and length measurements are critical for regulating and controlling the production processes in the steel and aluminum industry with its continuous or quasi-continuous production of slabs, bars, tubes and sheets. Harsh, hot and hostile fabrication environments significantly complicate measurements leaving only advanced non-contact measurement technology to provide the required precision and reliability.
Polytec`s Laser Surface Velocimeter LSV-6000 system uses proven laser Doppler technology to perform highly accurate non-contact speed and length measurements of moving surfaces in industrial production environments. The LSV measures the frequency shift of back-scattered laser light from a moving object to determine its velocity and length (Doppler Effect). The velocimeter system is composed of the LSV-6200 controller and a non-contact optical sensor head LSV-026. The system works on all types of materials, including rod, bar, tube, pipe, billets and slabs. Measurements can be performed on surfaces up to 1200 °C. For OEM applications or integration into sub-system a different sensor head, the LSV-065, which is itself a class IP65 housing, is available as a stand-alone component.
