The laser Doppler velocimeter was operated in the dual-beam near full backscatter mode and is composed of a 600 mW argon-Ion laser, a diffraction-grating unit to divide the light beam into two equal intensity beams and to provide frequency shift, and collimating and focusing lenses to form the control volume. Polytec's commitments are to provide the most precise and reliable optical instruments and sensors available for non-contact measurement, setting them apart from the competition as the gold standard in the design and manufacture of Vibrometer and Velocimeter systems. : a device for measuring speed (as of fluid flow or sound). Bâtiment Orion. Mass Flow Regulation Hydraulic Gap Control LSV LSV v0 h0 h1 v1 Mass Flow Regulation in a Rolling Mill with a C-frame and an integrated Laser Surface Velocimeter In order to meet the dimensional accuracy and tolerance specified by automotive and industrial consumers, modern rolling mills. Non-contact Precision Speed & Length Measurement Precision speed and length measurements are critical for optimization of continuous or quasicontinuous production processes such as those used. Sie arbeiten ohne Verschleiß und sind auch im Dauerbetrieb rund um die Uhr wartungsfrei. ; and Feller, W. Speed and Length sensors. Polytec’s compact velocimeters allow you to contactlessly measure both the length and the velocity of continuous material and piece goods. The value-engineered, LSV-300 Laser Surface Velocimeter utilizes Polytec's [] industry-proven technology to deliver the highest quality speed and length measurement at an extremely attractive price performance ratio.
