  • Page 8: Sitrans Lg200 Overview

    SITRANS LG200 Overview 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 device consists of an electronic enclosure coupled to a coaxial probe, single or twin solid rod, or flexible cable probes.

  • Page 83: Level Applications

    Application Troubleshooting Media buildup on the probe and stratification are common application concerns. Media buildup on the probe is not a problem in most cases, but when it occurs, it can be viewed as two types: Film Coating and Bridging. A twin rod probe can be used when minor film coating is a possibility.

  • Page 84: Interface Applications

    Interface Applications It is not uncommon for interface applications to have an emulsion layer form between the two media. This emulsion layer may pose problems for Guided Wave Radar as it may decrease the strength of the reflected signal. Since the properties of this emulsion layer are difficult to quantify, applications with emulsion layer should be avoided with SITRANS LG200.

    Appendix C: Technical Reference SITRANS LG200 is a loop-powered two-wire level transmitter based on the concept of Guided Wave Radar. Guided Wave Radar, or Micropower Impulse Radar (MIR), is a revolutionary, new level measurement technology. Micropower Impulse Radar (MIR) MIR (Micropower Impulse Radar) combines TDR (time domain reflectometry), ETS (equivalent time sampling) and modern low power circuitry.

  • Page 86: Equivalent Time Sampling (Ets)

    Equivalent Time Sampling (ETS) ETS (Equivalent Time Sampling) is used to measure the high speed, low power EM energy. ETS is a critical key in the application of TDR to vessel level measurement technology. The high speed EM energy (1000 ft/μs) is difficult to measure over short distances and at the resolution required in the process industry.

    By knowing the time between the first and second reflections, along with knowing the upper layer dielectric constant, the thickness of the upper layer can be determined. In order to properly process the reflected signals, the SITRANS LG200 is specified for those applications where the thickness of the upper layer is greater than 2 inches.
