Siemens SITRANS LG200 Guided Wave Radar Transmitter

Siemens SITRANS LG200 is a guided wave radar transmitter for short and medium range level, level/interface and volume measurement of liquids and solids. It is unaffected by changes in process conditions, high temperatures and pressures, and steam. The LG200 provides accurate measurement in level, volume, and interface applications. For short and extended applications, LG200 offers coaxial, single or twin rod probes, and single or twin cable probes up to 75 feet.

Looking for guided wave radar for hygienic liquids, aggressive media, or solids? See the new SITRANS LG guided wave radar transmitters.

Key Specifications

  • Loop-powered guided wave radar transmitter for level measurement in liquids, slurries, interfaces, and bulk solids
  • Combines technologies of time-domain reflectometry (TDR) and equivalent time sampling (ETS)
  • Measures accurately on materials with dielectric as low as 1.4
  • Reliable level measurement on harsh applications with pressure up to 6250 psi and temperatures as high as 800°F (427°C)
  • Measurement accuracy to 2.5 mm (0.12")
  • One transmitter head for many applications; Simplifies operations and reduces cost of stocking parts and training operators
