The 8X00 series guided wave radar level meters are electromagnetic wave ranging systems based on the principle of time travel. The 1GHz low-power electromagnetic wave signal emitted by the instrument probe spreads at the speed of light along the detection component (probe rod or detection cable). When electromagnetic waves come into contact with the surface of the measured substance, they are reflected back due to a sudden change in dielectric constant. The reflected electromagnetic wave spreads along the detection component and returns to the instrument probe. The time interval between the emission and reception of electromagnetic waves is proportional to the distance from the instrument probe to the measured mediumand, thus the distance between the instrument probe and the surface of the measured medium calculated.<\/p>\n","protected":false},"featured_media":3485,"parent":0,"menu_order":0,"template":"","tags":[],"product":[497],"size":[],"material":[],"class_list":["post-3484","products","type-products","status-publish","has-post-thumbnail","hentry","product-radar-level-meter","post1-3484"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/products\/3484","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/products"}],"about":[{"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/types\/products"}],"version-history":[{"count":3,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/products\/3484\/revisions"}],"predecessor-version":[{"id":3919,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/products\/3484\/revisions\/3919"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/media\/3485"}],"wp:attachment":[{"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/media?parent=3484"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/tags?post=3484"},{"taxonomy":"product","embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/product?post=3484"},{"taxonomy":"size","embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/size?post=3484"},{"taxonomy":"material","embeddable":true,"href":"https:\/\/www.rettar.com\/en\/wp-json\/wp\/v2\/material?post=3484"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
