SITRANS LR250 FEA Radar Level Transmitter - Flanged Encapsulated Antenna

Brand: Siemens AG
Does not ship to United States
SITRANS LR250 with flanged encapsulated antenna is a 2-wire, 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries in storage and process vessels including corrosives or aggressive materials, to a range of 20 m (66 ft) (antenna dependent).
Features
  • Fully encapsulated horn antenna design with FDA approved TFM 1600 PTFE lens for use in chemical and sanitary environments where aggressive and corrosive materials are used 
  • Cost effective replacement for transmitters made of exotic materials 
  • 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 and 50 mm (2 inch) process connection/antenna allow for easy mounting 
  • Insensitive to mounting location and obstructions, and less sensitive to nozzle interference 
  • Short blanking distance for improved minimum measuring range to 50 mm (2 inch) from the end of the antenna 
  • Communication using HART, PROFIBUS PA, or FOUNDATION Fieldbus 
  • 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 
  • Functional Safety (SIL 2). Device suitable for use in accordance with IEC 61508 and IEC 61511 
  • Suitable for API 2350
