Microwave Resonance Method

The moisture Analyzer in daily use, there are a number of different methods that find application in moisture analyzers. While the measuring principle is a method based on the microwave resonance method. This special with a moisture meter uses the dipole properties of water molecules method. In the sensor or sensor a special harmonic electromagnetic resonance environment produced by the generator of the moisture measuring device. The water bound into the material to be tested in interaction is thus linked to this resonance environment. The field changes are then collected by a detector, evaluated in the control unit, and then visually displayed. The resonance frequency of the micro wave field is annoyed depending on the water content of the tested material and steamed. This increases the width of the resonance curve thus.

This two different measurement and evaluation by means of the moisture Analyzer allows to determine the moisture content and the density of the material to be examined separately. One as a result, larger groups of molecules or ions can not simply follow the field changes and thus falsify the measuring result not reaching high selectivity of water. A low microwave power that is used in the conduct of the examination, not leads to chemical changes of the material to be examined. The water content of the material is chosen over the ill-feeling and damping of frequency of the resonator. The heating of the material to be tested does not take place due to the low energy input in the microwave (a few milliwatts). Since microwave ovens have the property to penetrate materials, completely all the bound water is captured in the material and heated. While the adherent surface water as well as water-bound by capillary condensation is included in the measurement result.
