 Technology  FMCW radar
 Range  50m (164 ft)
 Process Temperature  -40 to 250 °C (-40 to 482 °F)
 Process Pressure  Up to 40 bar g (580 psi g)



  • 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.
  • 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 or high pressure, low dielectric media, such as LPG (liquid, petroleum, gas).


  • 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
