They operate on the production line on materials moving at high speed, even when hot, dirty or difficult to access. They use two high-precision laser triangulation sensors positioned one above and one below the product, or interferometric or confocal chromatic sensing techniques for very high resolution measurements on transparent or semi-transparent products.  <\/p>\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-cover is-light popmake-11245\" style=\"border-width:1px;border-top-left-radius:10px;border-top-right-radius:10px;border-bottom-left-radius:10px;border-bottom-right-radius:10px;min-height:250px;aspect-ratio:unset;\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"213\" class=\"wp-block-cover__image-background wp-image-14896 size-large\" alt=\"banner aiuto nella scelta dello strumento oppure della tecnologia\" src=\"https:\/\/roder.it\/wp-content\/uploads\/2026\/06\/banner_technical_support_choose_products-1024x213.png\" data-object-fit=\"cover\" srcset=\"https:\/\/roder.it\/wp-content\/uploads\/2026\/06\/banner_technical_support_choose_products-1024x213.png 1024w, https:\/\/roder.it\/wp-content\/uploads\/2026\/06\/banner_technical_support_choose_products-300x63.png 300w, https:\/\/roder.it\/wp-content\/uploads\/2026\/06\/banner_technical_support_choose_products-768x160.png 768w, https:\/\/roder.it\/wp-content\/uploads\/2026\/06\/banner_technical_support_choose_products.png 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><span aria-hidden=\"true\" class=\"wp-block-cover__background has-background-dim\" style=\"background-color:#d3d6dc\"><\/span><div class=\"wp-block-cover__inner-container is-layout-constrained wp-container-core-cover-is-layout-a304f9a9 wp-block-cover-is-layout-constrained\">\n<p class=\"has-text-align-right has-ti-fg-color has-text-color has-link-color wp-elements-1 wp-block-paragraph\" style=\"font-size:clamp(21.536px, 1.346rem + ((1vw - 3.2px) * 1.726), 35px);\"><strong>Would you like help choosing the right product ?<\/strong><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-right is-layout-flex wp-container-core-buttons-is-layout-b507c051 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/roder.it\/en\/contacts\/\">Click here !<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h2 class=\"wp-block-heading\">Dual-sensor principle<\/h2><p class=\"wp-block-paragraph\">The most widespread configuration for measuring sheet thickness uses two synchronised laser triangulation sensors, positioned one above and one below the moving product. Each sensor measures the distance from its own side of the product; knowing the distance between the two sensors (constant, calibrated gap), the thickness is obtained as the difference between the total gap and the sum of the two distances. To guarantee stable performance, the mechanical stiffness of the frame and periodic calibration of the gap are essential. Typical resolutions: 0.1-1 \u00b5m on products up to 50 mm thick.   <\/p><h2 class=\"wp-block-heading\">Dedicated techniques<\/h2><p class=\"wp-block-paragraph\">For special applications the following are used: chromatic confocal sensors (for the thickness of transparent materials such as glass, plastic and films, with simultaneous measurement of thickness and refractive index); structured light systems (for complex surfaces); laser interferometers (for very high resolution on limited thicknesses); X-ray thickness gauges (for metal thicknesses where lasers are limited by surface roughness). Each technique has specific advantages depending on the material and the process conditions. <\/p><h2 class=\"wp-block-heading\">Applications<\/h2><p class=\"wp-block-paragraph\">Non-contact laser systems are used in cold and hot rolling lines for steel, aluminium and copper; in the extrusion of plastic films for packaging; in the production of thin foils for the electronics and battery industries; in the measurement of tube walls in production (LWM &#8211; Laser Wall Thickness Measurement); in rubber calendering; in paper and board production; and in the coating of continuous strips (for controlling the coating thickness). Line speeds reach hundreds of m\/min with no compromise on performance. <\/p><h2 class=\"wp-block-heading\">Benefits<\/h2><p class=\"wp-block-paragraph\">The main advantages over traditional methods (UT, radioactive isotopes, measuring wheels) are: no contact with the product (no marking and no wear), no radiation (a regulatory and safety advantage over X-ray or gamma systems), high acquisition frequency (1-10 kHz), a wide range of measurable materials, real-time integration with control systems for automatic line regulation (closed loop), and the ability to measure even very hot or wet products.<\/p><h2 class=\"wp-block-heading\">Safety and selection criteria<\/h2><p class=\"wp-block-paragraph\">The systems are classified according to IEC 60825-1 (generally class 2 or 3R). Laser safety in the workplace is managed with optical barriers, shielding and lockout procedures for maintenance. System selection depends on: thickness range, product width, line speed, the material and its optical reflectivity, product temperature, integration with the line PLC and MES, and reporting requirements. Sizing requires technical analysis with the supplier and preliminary tests on the real product to validate performance.   <\/p>\n<h2 id=\"prodotti-collegati\" class=\"wp-block-heading has-ti-accent-color has-text-color\">Related products<\/h2>\n\n<p class=\"wp-block-paragraph\">The RODER instruments for this application.
