Areas of Application Measuring Principle

Using the Micro-Polar, the concentration, the dry sub-stance or the water content is measured. The product can be in fluid, suspension, paste or powder form. Measuring can take place in pipelines, vessels or in other process related system parts using the different sensors. Typical areas of application are amongst others, mea- surement of cream cheese, butter, milk of lime, gypsum suspension, silicic acid etc. In the tried and tested transmission technology, micro- waves penetrate the product which causes different strengths of polarisation of the material components. Especially, water molecules can be measured very sel- ectively and accurately, since the free water molecules are polarised due to their natural structure. As a result, the propagation velocity of the micro-waves is slowed down (phase shift) and their intensity is weakened (attenuation). Both effects are measured by Micro-Polar and are used as an indication of con- centration or water content. The multi-frequency technology allows the measure-ment at a variety of individual frequencies per measu- ring cycle, therefore a very stable and reliable measu– rement can be guaranteed after plausibility analysis.The modern technology applies very weak microwaveswhich are completely harmless for humans and the environment.
