With a narrow 9\u00b0 beam angle, the sensor effectively suppresses false echoes caused by tank structures, turbulence, or environmental interference, ensuring reliable level readings.<\/p>\n<p>The device supports level display, control, and alarm functions in a single unit, making it an ideal solution for automated liquid level control systems. Optional relay outputs enable high-level and low-level alarm control, allowing direct linkage with pumps and valves.<\/p>\n<p>Two antenna configurations are available:<\/p>\n<p>Lens Antenna Version \u2013 Suitable for various media, including liquids with impurities or turbulence<\/p>\n<p>Basic Antenna Version \u2013 Recommended for clean, non-corrosive, impurity-free liquids<\/p>\n<p>With robust materials, IP65 protection, and wide power supply options, the ERT-A2120 delivers long-term stability and low maintenance in complex field conditions.<\/p>","protected":false},"excerpt":{"rendered":"<div class=\"flex flex-col text-sm pb-25\">\n<article class=\"text-token-text-primary w-full focus:outline-none [--shadow-height:45px] has-data-writing-block:pointer-events-none has-data-writing-block:-mt-(--shadow-height) has-data-writing-block:pt-(--shadow-height) [&amp;:has([data-writing-block])&gt;*]:pointer-events-auto scroll-mt-[calc(var(--header-height)+min(200px,max(70px,20svh)))]\" dir=\"auto\" tabindex=\"-1\" data-turn-id=\"request-69a788d5-9e20-8324-8b63-2b8d8d876a3c-16\" data-testid=\"conversation-turn-42\" data-scroll-anchor=\"true\" data-turn=\"assistant\">\n<div class=\"text-base my-auto mx-auto pb-10 [--thread-content-margin:--spacing(4)] @w-sm\/main:[--thread-content-margin:--spacing(6)] @w-lg\/main:[--thread-content-margin:--spacing(16)] px-(--thread-content-margin)\">\n<div class=\"[--thread-content-max-width:40rem] @w-lg\/main:[--thread-content-max-width:48rem] mx-auto max-w-(--thread-content-max-width) flex-1 group\/turn-messages focus-visible:outline-hidden relative flex w-full min-w-0 flex-col agent-turn\" tabindex=\"-1\">\n<div class=\"flex max-w-full flex-col grow\">\n<div class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal [.text-message+&amp;]:mt-1\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"65e98cd3-1e69-4be4-8177-b10fddd9c661\" data-message-model-slug=\"gpt-5-2\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[1px]\">\n<div class=\"markdown prose dark:prose-invert w-full wrap-break-word light markdown-new-styling\">\n<p data-start=\"2\" data-end=\"105\">ERT-A2120 high-frequency radar level transmitter for non-contact liquid level measurement and control<\/p>\n<p data-start=\"108\" data-end=\"163\">Integrated design for high-precision level monitoring<\/p>\n<p data-start=\"166\" data-end=\"206\">\u00b12 mm accuracy for precise measurement<\/p>\n<p data-start=\"209\" data-end=\"280\">60 GHz high-frequency radar technology for fast and reliable response<\/p>\n<p data-start=\"283\" data-end=\"357\">Suitable for wastewater, rivers, reservoirs, and tank level applications<\/p>\n<p data-start=\"360\" data-end=\"417\" data-is-last-node=\"\">Ideal for demanding industrial and municipal environments<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"z-0 flex min-h-[46px] justify-start\"><\/div>\n<div class=\"mt-3 w-full empty:hidden\">\n<div class=\"text-center\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/article>\n<\/div>\n<div class=\"pointer-events-none h-px w-px absolute bottom-0\" aria-hidden=\"true\" data-edge=\"true\"><\/div>\n","protected":false},"featured_media":1259,"template":"","meta":{"content-type":""},"product_brand":[],"product_cat":[3,58],"product_tag":[],"class_list":["post-1254","product","type-product","status-publish","has-post-thumbnail","product_cat-level","product_cat-level-transmitter","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/www.elecall.cn\/zh\/wp-json\/wp\/v2\/product\/1254","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.elecall.cn\/zh\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.elecall.cn\/zh\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.elecall.cn\/zh\/wp-json\/wp\/v2\/media\/1259"}],"wp:attachment":[{"href":"https:\/\/www.elecall.cn\/zh\/wp-json\/wp\/v2\/media?parent=1254"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.elecall.cn\/zh\/wp-json\/wp\/v2\/product_brand?post=1254"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.elecall.cn\/zh\/wp-json\/wp\/v2\/product_cat?post=1254"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.elecall.cn\/zh\/wp-json\/wp\/v2\/product_tag?post=1254"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
