When mounted on the outside wall of a container, it can detect whether liquid is present at a specific monitoring point.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This makes the sensor suitable for applications where direct contact with the liquid is undesirable or where the container needs to remain sealed. <\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Key Features<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The DYP-L02 provides:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Non-contact liquid level measurement<\/li>\n\n\n\n<li>2.8\u20135 V operating voltage<\/li>\n\n\n\n<li>20\u20132000 mm liquid level measurement range<\/li>\n\n\n\n<li>1 mm resolution<\/li>\n\n\n\n<li>Real-time tracking across the measurement range<\/li>\n\n\n\n<li>Multiple output configurations<\/li>\n\n\n\n<li>Adaptive blind-zone detection<\/li>\n\n\n\n<li>Operating temperature from -15\u00b0C to +60\u00b0C<\/li>\n\n\n\n<li>Storage temperature from -25\u00b0C to +80\u00b0C<\/li>\n\n\n\n<li>ESD protection compliant with IEC 61000-4-2<\/li>\n\n\n\n<li>Compact sensor design<\/li>\n\n\n\n<li>Automatic and triggered operating modes<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The sensor uses an intelligent algorithm to identify container characteristics and automatically adapt its blind zone. <\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Typical Applications<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The L02 can be used for liquid detection through containers made from dense materials including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Steel<\/li>\n\n\n\n<li>Iron<\/li>\n\n\n\n<li>Glass<\/li>\n\n\n\n<li>Ceramic<\/li>\n\n\n\n<li>Non-foamed plastics<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It is intended for clean, single-component liquids or miscible liquid mixtures without substantial sediment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical applications include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Smart drinking cups<\/li>\n\n\n\n<li>Smart beer kegs<\/li>\n\n\n\n<li>Smart liquefied-gas systems<\/li>\n\n\n\n<li>Intelligent liquid-control equipment<\/li>\n\n\n\n<li>Sealed-container liquid monitoring<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For reliable measurement, the container should have a reasonably regular shape and a relatively flat mounting surface. <\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Technical Specifications<\/h2>\n\n\n\n<figure
