While using intelligent compact transmitters has always been attractive, certain limitations prevented their use in many applications. LST300 removes those old obstacles. Whether you have the risk of flooding or corrosive materials in the process, LST300 survive these conditions easily. With metal at the top and PVDF at the bottom, LST300 is the first compact ultrasonic to be resistant to corrosion on the entire instrument. Ingress protection approvals up to IP68 (optional) ensure the entire device can survive flooding.<\/p>\n<p>LST300 combines the most advanced functions found on any ultrasonic in any class, in a compact form. Installation becomes easy thanks to the graphic echo display and advanced diagnostics. The false echo filtering algorithm combined with the best\u2011in\u2011class beam angle ensures easy installation in narrow areas with many obstructions. With through the glass technology, you never have to open the cover to configure the instrument. It is hard to believe that all this functionality is available on a device powered by only two\u2011wire loop power.<\/p>\n<p><span style=\"color: #ff0000;\"><strong>FEATURES:<\/strong>\u00a0<\/span><\/p>\n<ul>\n<li>Maintenance free, non-contact continuous level sensor<\/li>\n<li>2-wire instrument with HART digital communication<\/li>\n<li>Up to 10 m measurement range<\/li>\n<li>Wide temperature range of -40 to 85 \u02daC<\/li>\n<li>Accuracy of \u00b12 mm or 0.2 % of full span (the larger one)<\/li>\n<li>Beam angle as low as 5\u02da with false echo filtering for narrow spaces<\/li>\n<li>Easy installation with graphic echo display, advanced diagnostic and easy setup menu<\/li>\n<li>Unique GAP technology ensures the best performance under any condition<\/li>\n<li>IP66\/67 and NEMA 4X (can submerge to 1 m depth for 30 minutes)<\/li>\n<li>ATEX, IEC &amp; FM Intrinsic safe and non sparking approved<\/li>\n<\/ul>\n<p><span style=\"color: #ff0000;\"><strong>OPTIONS:<\/strong><\/span><\/p>\n<p>\u2014 Through the Glass (TTG) buttons, standard push buttons or without HMI interface<br \/>\n\u2014 6 m (20 ft.) or 10 m (32 ft.) measurement range<br \/>\n\u2014 FM, ATEX, IECEx or NEPSI approved, intrinsically safe or non\u2011sparking<br \/>\n\u2014 Standard, extendable or floor mounted brackets available for easy installation<br \/>\n\u2014 Flange mounting options<\/p><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"sfContentBlock\"><\/div>\n<div class=\"sfContentBlock\">\n<p>The on\u2011board microprocessor simultaneously fires an electronic pulse and starts a timer. The transducer converts this electronic pulse to an acoustic pulse, which is directed toward the surface of the material being measured. When the acoustic pulse contacts the surface of the material, energy is reflected back to the transducer, which converts the energy back to an electronic pulse. This pulse is sent back to the microprocessor, which stops the timer and determines the time\u2011of\u2011flight of the signal. By combining the speed of sound through air and the time\u2011of\u2011flight of the pulse, the microprocessor accurately determines the level of the product. Powerful software removes false echoes from the signal and electronic filters remove ambient noise.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-797\" src=\"http:\/\/abb.quad-industry.com\/wp-content\/uploads\/2020\/12\/ultrasonic-measurement.jpg\" alt=\"ultrasonic-measurement\" width=\"600\" height=\"234\" srcset=\"https:\/\/abb.quad-industry.com\/wp-content\/uploads\/2020\/12\/ultrasonic-measurement.jpg 600w, https:\/\/abb.quad-industry.com\/wp-content\/uploads\/2020\/12\/ultrasonic-measurement-300x117.jpg 300w, https:\/\/abb.quad-industry.com\/wp-content\/uploads\/2020\/12\/ultrasonic-measurement-513x200.jpg 513w, https:\/\/abb.quad-industry.com\/wp-content\/uploads\/2020\/12\/ultrasonic-measurement-512x200.jpg 512w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<\/div>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #ff0000;\"><strong>Catalog and Questionnaire List<\/strong><\/span><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-798 alignleft\" src=\"http:\/\/abb.quad-industry.com\/wp-content\/uploads\/2020\/12\/DS_LST300-EN_D-2019.05.pdf.jpg\" alt=\"DS_LST300-EN_D 2019.05.pdf\" width=\"90\" height=\"120\" \/><span class=\"dsTitle\"><a href=\"http:\/\/abb.quad-industry.com\/pdf\/DS_LST300-EN_D 2019.05.pdf\" target=\"_blank\">Data sheet &#8211; LST300 | Compact ultrasonic level transmitter<\/a><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The LST300 is a high performance ultrasonic level transmitter that accurately measures level, distance and open channel flow in ranges up to 10m (30ft).
