With microwave measuring systems from Berthold, a global technology leader in the field of radiometric measuring systems, concentration, density or dry matter can be measured in a wide variety of products, in the running process, on pipelines or containers. The areas of application for these microwave systems are diverse – including the food industry – and the range of sensors is correspondingly large. According to the supplier, the special technical features, such as checking the plausibility of measured values or very high measurement and frequency dynamics, set new standards.

The microwave measuring system uses the dielectric property of water. It generates microwaves that interact with the water molecules. This interaction causes a weakening of the microwave energy, which can be detected as phase shift and attenuation. Since the phase shift and attenuation change is directly proportional to the water content in the product, the concentration or the dry content in the medium can be determined very precisely. Berthold's special multi-frequency technology enables very stable and reliable measurements, unaffected by interfering reflections or resonances. The microwave power of the measuring system is so low (maximum 10 mW) that the material to be measured is neither heated nor changed in any way.

The system is suitable for use with dairy products, egg whites, sugar, caramel as well as chocolate, for example. It can be easily installed in existing pipelines, containers or tanks. An intuitive, user-friendly interface simplifies configuration and calibration.
