© Siemens AG 2013 Level Measurement Continuous level measurement — Radar transmitters SITRANS LR400 ■ Overview ■ Application It provides excellent results on low dielectric media. SITRANS LR400 is available for standard applications and for applications that require explosion proof protection. SITRANS LR400 features robust enclosure, flange and horn components. It is virtually unaffected by atmospheric or temperature conditions within the vessel. Safe on-site local programming is simple using the Intrinsically Safe handheld programmer. SIMATIC PDM can be used for easy remote programming. The characteristics of 24 GHz and high signal-to-noise ratio contribute to exceptional signal reflection, regardless of the dielectric value of the medium. • Key Applications: long-range liquid or slurry applications, high temperature [up to 250 °C (480 °F)] or high pressure, low dielectric media, such as LPG (liquid, petroleum, gas) without the need for stilling pipes The SITRANS LR400 is a 4-wire, 24 GHz FMCW radar level transmitter for continuous monitoring of liquids and slurries in storage and process vessels including high temperature and high pressure, to a range of 50 m (164 ft); ideal for low dielectric media. ■ Benefits • • • • • • • Easy installation and commissioning, low maintenance Self-calibration with internal reference Built-in diagnostics Auto False-Echo Suppression and advanced echo processing 24 GHz and high signal-to-noise ratio Communication using HART or PROFIBUS PA Programming using infrared Intrinsically Safe handheld programmer or with SIMATIC PDM or HART handheld device ■ Configuration Beam angle 13° Mounting unit on vessel 3" short horn antenna 4" long horn antenna 10 (0.39) 9° Installation in mounting nozzle Conical Parabolic Note: For best signal, always use largest horn size possible.
