SL

SL Series non-contact, unidirectional speed and length gauges provide extremely accurate speed and length measurements in almost any production environment.

Production processes for wire, cable, web products, woven and non-woven materials, paper, plastic film, tapes, building materials, floorings 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.

SL 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.
