Benefits

SITRANS LR250 Horn antenna

• Graphical local user interface (LUI) makes operation simple with plug-and-play setup using the intuitive Quick Start Wizard


• LUI displays echo profiles for diagnostic support


• 25 GHz high frequency allows for small horn antennas for easy mounting in nozzles


• Insensitive to mounting location and obstructions, and less sensitive to nozzle interference


• Short blanking distance for improved minimum measuring range to 50 mm (2″) from the end of the horn


• Communication using HART® or PROFIBUS PA, or FOUNDATION Fieldbus TM


• Process Intelligence signal processing for improved measurement reliability and Auto False-Echo Suppression of fixed obstructions


• Programming using infrared Intrinsically Safe handheld programmer or over a network using SIMATIC PDM, Emerson AMS, or Field Device Tools, such as PACTware or Fieldcare via SITRANS DTM.
