Code: 7ML5421
Product name: SITRANS LR400

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

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