State of the art measurement technology
Concentration measuring principle by Berthold!
Microwaves are highly sensitive to water molecules. When penetrating the measured material the microwaves cause a rotation of the free water molecules. As a result the velocity of the microwave is slowed down (phase shift) and their intensity is weakened (attenuation). Both effects are measured, allowing for a very stable measurement. Phase shift and attenuation are a direct measure for the water content, out of which concentration or dry substance is indicated.
These measuring effects are already achieved by using very small microwave transmission power – typically 0.1 mW. Consequently the measured material is neither warmed nor modified. With the microwave transmission principle used by Berthold, the whole material cross-section is penetrated. Therefore the measurement is highly accurate and representative. Factors such as colour, viscosity, inhomogeneous composition or dust have no or only a negligible effect on the measurement performance.
Quality and safety
- Precise and reliable
- Robust system design
- Maintenance-free operation
Simply and intuitive operation
- Online process control for real-time process information
- Measurement of both: phase shift and attenuation
- Highly representative due to transmission principle
- Easy to install on existing pipelines, vessels or tanks
Online concentration measurement in liquids
Microwave measurement takes place online during the running process, providing real-time information on concentration, density, dry matter or water content in liquids, suspensions and pastes. A high degree of accuracy characterizes the extremely reliable measuring systems. The various sensors are robust and can be installed on containers or in pipelines and can be used for various fluids, pastes and powders.
A variety of applications range from the food industry to wastewater treatment, power plants and the chemical industry.
