Using the microwave system from Berthold, the water content or dry
content of fluids and solid matters can be measured online.
Depending on the application, various microwave sensors can be applied:
For example
Insertion sensors for the measurement in process containers or
crystallizers
Pipeline sensors for the inline measurement in pipe.
Horn antenna for the measurement on a conveyor belt or in a chute.
The suitable measuring arrangement can be configured by the wide
spectrum of sensors.
Measuring Principle
The microwave irradiates the product with very little power (< 0.1
mW). The material components are polarised at different strengths and as
a result of this, the microwaves lose on speed and energy. Thereby, the
speed reduction brings about a phase shift and the weakening of the
energy effects an attenuation of the microwave.
If there are free charged particles in the product or polar materials
like water molecules H2O, then this effect is disproportionately
intensified. The water influence is 40-times larger as the influence of
other components. Hence, it is clear how selectively sensible the water
components can be measured.
Figure 1 to 3 only shows a section of a possible arrangement. Basically a
measuring system always consists of:
An evaluation unit including a microwave module
A set of high frequency cables and
A microwave sensor or two antennae.
Radiometric area weight compensation can complement the measurement on
bulk goods as an option, see arrangement 3. When strong fluctuations
occur, the measuring accuracy can be increased considerably.
Advantages:
High accuracy by selective sensitivity to water.
Representative measurement by recording of the complete material
interface.
Simple installation by computerised sample taking and automatic
calibration.
Robust sensors, use of wear resistant materials.
Contactless, dependeing on sesor.
Very low amount of maintenance.
