Flammable gases, vapors, mists or dusts come into contact with air in a defined concentration range. <\/p>\n\n<p>In such <strong>hazardous areas<\/strong>, electrical equipment can become a <strong>source of ignition<\/strong>, for example due to electrostatic discharge, sparking, hot surfaces or mechanically generated friction energy. For this reason, only appropriately <strong>certified<\/strong> <strong>explosion-proof<\/strong> scales may be used here: so-called <strong>scales <\/strong>with<strong> ATEX-compliant components <\/strong>and the appropriate device category\/EPL for the zone or <strong> <\/strong><strong> ATEX<\/strong> or <strong>explosion-protected scales<\/strong> for short.<\/p>\n\n<p>Find out what makes an <strong>ATEX\/Ex-protected scale<\/strong> special, which <strong>Ex zones<\/strong> and <strong>protection classes<\/strong> are relevant in practice &#8211; and what you should look out for when selecting and operating a <strong>certified Ex-protected scale<\/strong> or realistically evaluating <strong>Ex-protected scales<\/strong> as part of a <strong>price comparison<\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">What is an explosion-protected scale?<\/h2>\n\n<p>An <strong>explosion-proof scale<\/strong> is designed for areas in which an <strong>explosive atmosphere<\/strong> can occur, for example due to flammable <strong>gases, vapors\/mist<\/strong> or <strong>dusts<\/strong>. The scale is designed and <strong>certified<\/strong> so that it <strong>does not<\/strong> represent an <strong>effective ignition source<\/strong> under defined conditions. <\/p>\n\n<p>Important: &#8220;Ex-protected&#8221; is a <strong>normatively and legally regulated<\/strong> status. In Europe, this is based in particular on: <\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>ATEX Equipment Directive 2014\/34\/EU<\/strong>: Regulates the placing on the market of equipment and protective systems intended for use in potentially explosive atmospheres.<\/li>\n\n\n\n<li><strong>ATEX Directive 1999\/92\/EC<\/strong>: Regulates minimum requirements for the safety and health protection of employees in hazardous areas (including zoning, organizational measures).<\/li>\n<\/ul>\n\n<p>In Germany, appliance safety is implemented via the <strong>11th ProdSV<\/strong>, among other things. For operators, this includes a documented risk assessment including zone classification and explosion protection document, plus a defined testing and maintenance concept. <\/p>\n\n<h2 class=\"wp-block-heading\">ATEX, Ex zones and device categories: The basics that really count<\/h2>\n\n<p>Many decisions regarding an Ex scale do not depend on the weighing range, but on the environment: How often does an explosive atmosphere occur, and in what form? This is exactly where the <strong>Ex zones<\/strong> come from. <\/p>\n\n<p>For orientation purposes, hazardous areas are typically categorized as follows:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Gases\/vapors\/mist<\/strong>: <strong>Zone 0, 1, 2<\/strong> (frequent to rare)<\/li>\n\n\n\n<li><strong>Dusts<\/strong>: <strong>Zone 20, 21, 22<\/strong> (frequent to rare)<\/li>\n<\/ul>\n\n<p>The more critical the zone, the higher the requirements for the appliance (appliance category\/protection level). In practice, this means that a scale that is approved for a more stringent zone can also be used in less stringent zones, provided the gas\/dust group and temperature specifications are suitable &#8211; but not vice versa. <\/p>\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.essmann-shop.com\/geeicht-lieferbare-tischwaage-dini-gex-fz620-1g-hoechstlast-0-62-kg-waegeflaeche-durchmesser-140-mm-edelstahl-atex\/60da00986\" target=\"_blank\" rel=\" noreferrer noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"900\" height=\"975\" src=\"https:\/\/essmann.com\/wp-content\/uploads\/2026\/03\/gex_xs_waage.jpg\" alt=\"Explosion-proof stainless steel scale Scale 'ATEX DINI GEX-FZ620-1G' made of metal with digital display and keypad.
