SL mini Series

Features Non-contact, high-speed, solid-state laser speed and length measurement with no slippage, drift, mechanical wear or maintenance compared with contact wheel / roller systems. Unidirectional speed and length measurement. Ultra-compact design with a footprint comparable to a smartphone. Optimized for sheet material and converting applications. UKAS-traceable calibration; accuracy better than 0.05% and repeatability better than 0.02%. Rugged industrial design for use in factory environments. Available fitted with industry-standard communcations interfaces for easy integration with PLCs and production line equipment. Excellent value with low cost of ownership. Introduction Proton Products InteliSENS® SL mini Series non-contact, unidirectional speed and length gauges provide extremely accurate speed and length measurements in almost any sheet material or converting application. Production processes for web products, woven and non-woven materials, paper, plastic film, tapes, building materials, flooring and labelling can all be measured using the laser Doppler method. Applications requiring a precise cut-to-length process benefit from the non-slip and highly accurate laser measurement technique which reduces scrap, increases uptime and improves material yield by eliminating product “Give Away” or “Short Length” claims. InteliSENS® SL mini Series gauges are money-saving, direct replacements for traditional problematic and high-maintenance contact wheel and roller-type devices and are extremely easy to install and operate. Integration with production line controllers such as PLCs is eased by the availability of a wide variety of industry standard communications interfaces. Operating principle Laser surface velocimeter Proton Products InteliSENS® SL mini Series speed and length gauges illuminate the measured surface with an interference pattern created by the intersection of two laser beams. The alternating bright and dark interference fringes modulate the light scattered by the object with a frequency proportional to the object speed. This scattered light is detected by a photodiode and the electrical signal digitally processed to determine the frequency and hence the speed. Object length is then calculated by integrating the speed measurement over time.
