LSV 6000
 |
Polytec's Laser Surface Velocimeter LSV-6000 system performs highly accurate non-contact speed and length measurements of moving surfaces in industrial production environments. 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. The LSV 6000 is perfect for harsh, hot and hostile fabrication environments.

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.
LSV Series 6000 System
| The LSV Series 6000 system combines a sensor head, a controller and software into a rugged industrial packagedesigned specifically to measure velocity and length under the strenuous demands of mill environments. |
