Features and benefits The Velas DL4000-N directly replaces traditional, high-maintenance, problematic contact wheel and rollers type devices, with accurate “state-of-the-art” laser Doppler technology. Extremely easy to install, integrate and use. Accurate speed and length measurement reduces scrap, increases uptime and improves material yield. • • • • • • • • • • • High accuracy: better than 0.05%. Repeatability: better than 0.02%. Non-Contact: no slippage. Can measure on very high temperature products. No Moving Parts: no wear. Autonomous sensor: ready to use, no calibration required. Designed...

Presentation The Velas DL4000-N is an autonomous sensor mounted in cast aluminium housing. A hood for protecting the window glass is fitted with air purging to create an air curtain in front of this glass. The case includes a cooling stainless steel pipe and is fixed to a mounting stand, adjustable with three axes. The electrical connections are made with heavy duty connectors. The Velas DL4000-N has 3 possible standoff distances: 600 mm (red laser), 1200 and 2000 mm (infrared laser). It is proposed in two models: standard and bi-directional. The bi-directional velocimeters are used in applications...
