An ideal narrow beam radar level transmitter for textile additives Project at Beaulieu Technical Textiles Originally written in Dutch by Alfons Calders and published in Industrie Technisch & Management, a Belgian technical magazine (www.industrie.be). Translated into English by Siemens AG, with permission from the author. The cities of Comines-Warneton and Kruishoutem host two companies that are part of the Technical Textiles division of the Beaulieu International Group. Both companies use storage silos containing several types of polypropylene particles. Until recently, the level in each silo was monitored using a manual floattype detection device. To increase measurement efficiency and monitor level variations automatically, the system was replaced by a radar level measurement device, working with a frequency of 78 GHz, specifically designed to measure powders, pellets, or grains. Industrie Technique & Management discussed the details of this application with Bart De Bleeckere, Production & Operations Manager and JeanLuc Dejaeghere, Project Manager from Beaulieu Technical Textiles in Comines-Warneton, as well as Gert Davidson, Application Engineer Process Instrumentation & Analytics, from Siemens. Manufacturing technical fabrics The Beaulieu International Group (BIG), European market leader and international front-line player in the design, manufacturing and marketing sales of both rigid and soft floor coverings, furnishing fabrics, and

Beaulieu Technical Textiles purchases bulk quantities of polypropylene pellets. These pellets are stored in six silos throughout the plant. technical fabrics, is a Belgian industrial group created in 2005 by merging five independent branches of the Beaulieu group. BIG is an integrated vertical company, specializing in the production of raw materials, semifinished products, and finished goods. With thirty sales and production plants in eight countries and 3,500 employees throughout the world, the company generated a turnover of approximately 1.4 billion euros in 2012. The Comines-Warneton...

The SITRANS LR560 is currently the only instrument available on the market operating at a frequency of 78 GHz. Quick Start Wizard, the instrument is up and running in just a few minutes. Increased measurement accuracy thanks to higher frequency range Measuring level using radar technology involves the emission of short microwave pulses that are reflected by the surface of the liquid or bulk solid. The level is calculated based on silo dimensions. Normally, the frequency used in radar level measurement is 6 GHz or 26 GHz. This frequency is suitable for measuring liquids or coarse-grained...

Level transmitters are connected to the SITRANS RD500 remote data manager. With this system from Siemens, Beaulieu Technical Textiles can now perform inventory monitoring in the silos without any human intervention. instrument was equipped with a built-in air purge cleaning system that turned out not to be necessary for the application. The SITRANS LR560 is compatible with HART, Profibus PA, or Foundation Fieldbus protocols. For the latter, however, level measurements are transmitted via the 4 to 20 mA signal to a very user-friendly SITRANS RD500 remote data manager. This device includes a...
