15 December 2006 -- Sitrans LR 460 is the new continuous radar level measurement transmitter from Siemens Milltronics. Featuring 24 GHz FMCW (frequency-modulated continuous wave) technology and Process Intelligence echo processing, the Sitrans LR 460 defines unparalleled performance on difficult solids applications. Built on the award-winning Sitrans LR 400 platform, the Sitrans LR 460 is the ideal solution for solids applications containing extreme dust, high temperatures, and long ranges to 100 m (328 ft).
Virtually any solid medium can be measured, including cement powder, fly-ash, coal, gypsum, flour, grain, aggregates, and plastics.
With new Process Intelligence advanced echo-processing software and completely re-designed high frequency/high gain circuitry, Sitrans LR 460 is able to reliably measure these diffcult applications - without ever touching the material! Process Intelligence signal analysis of echoes received from the application is unmatched in the industry.
We have taken our field experience in over 500,000 applications and our patented Sonic Intelligence software (used on our ultrasonic transcievers) and applied it to our latest radar technology.
Very easy to set up, Sitrans LR 460 includes a brand-new Quick Start Wizard that can be enabled locally at the local display (included) or remotely via Simatic PDM.
After initial setup, Process Intelligence takes over, responding automatically to changing material slope conditions and physical silo features such as fixed obstructions or build-up.
The result is repeatable, fast, and reliable continuous measurement of your material during static, discharge, or filling conditions.
The new antenna system is designed for low loss and improved gain, thus increasing the signal-to-noise ratio an additional 20 dB over the previous Sitrans LR 400.
This innovation allows for detection of very low dielectric constant materials at long ranges.
This measurement is possible with a small horn antenna of only 100 mm (4inch) diameter; no large diameter parabolic dish is required.
Intense dust in the silo atmosphere does not attenuate the Sitrans LR 460 radar signal, as the device uses electromagnetic waves at 24 GHz traveling at the speed of light to measure the distance to the material surface.
With the built-in Easy Aimer, it is simple to install and orient the device.
You can position the transmitter perfectly relative to the sloped surface of the material, improving the return signal quality.
Ample room is provided for wiring and rugged screw terminals are provided, allowing fast and easy installation and wiring.
The infrared handheld programmer is non-intrusive, allowing the device to be programmed without opening the cover.
Extreme process temperatures up to 200C (392F) can be accommodated and your material temperature is unlimited.
Optional self-cleaning purging connection and dust covers are available to prevent sticky solids from building up inside the antenna.
