The first 78 GHz radar level transmitter for solids level measurement

01.02.2011
Siemens Industry Automation Division has launched Sitrans LR560, the first radar level transmitter operating at 78 GHz frequency.

Sitrans LR560 is a non-contacting 2-wire FMCW (Frequency Modulated Continuous Wave) radar level measurement transmitter with a measurement range of 100 meters (328 ft). The transmitter emits a narrow four degree beam which avoids silo wall obstructions and other installation interferences, allowing it to be installed practically anywhere on the top of the silo.


The Siemens Industry Automation Division launches the first radar level transmitter with a frequency of 78 GHz. The device is equipped with a newly developed lens antenna and uses the non-contacting FMCW technology.

As the first radar transmitter to operate at 78 GHz frequency, it emits a short wavelength to provide exceptional signal reflection even from solids with a steep angle of repose. The graphical Quick Start Wizard guides the user to get Sitrans LR560 operational in minutes for accurate and reliable level measurement readings without any additional fine-tuning.

Sitrans LR560 is available with HART®, PROFIBUS PA, or FOUNDATION™ Fieldbus protocol. Programming is supported locally with pushbuttons or with an infrared handheld programmer. The transmitter also supports remote configuration and diagnostics with Siemens Simatic PDM (Process Device Manager), Emerson AMS™, or PACTware™ using Siemens DTM. The local display interface features a backlit display and can be rotated to four positions for convenience. The unique lens antenna is highly resistant to material build-up and an integrated purge connection is included for cleaning exceptionally sticky solids material. The high frequency operation makes aiming unnecessary, but the optional aiming flange helps direct the beam to an area of specific interest, such as the discharge area of the silo cone.

Im Focus: The force of the vacuum

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.

The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
