Concentration, density, or dry matter can be measured in a wide variety of products, continuous processes, pipelines, and vessels using the microwave measuring systems from Berthold Technologies. From the food industry to power plants and the pharmaceutical industry – the fields of application for our microwave systems are manifold and the selection of sensors is correspondingly large. Our special technical features, such as checking the plausibility of measured values or very high measurement and frequency dynamics, set new standards.
The measuring principle
The microwave measuring system uses the dielectric property of water. The measuring system generates microwaves that interact with the water molecules. This interaction causes an attenuation of the microwave energy, which can be detected as phase shift and attenuation. Since the phase shift and attenuation changes are directly proportional to the water content in the product, the concentration or dry content in the medium can be determined with high accuracy.
Berthold‘s superior multi-frequency technology provides very stable and reliable measurements unaffected by interfering reflections or resonances. The microwave energy is so low (max. 10 mW) that the material to be measured is neither heated nor altered in any way.
