The GreCon On-line Moisture Measuring System MWF 3000 works according to the microwave resonance method. This method uses the dipole properties of
water molecules. A harmonic, electromagnetic resonance field (microwave field) is generated by means of the planar sensor. The water bound by the material now interacts with the resonance field.
The resonance frequency of the microwave field is detuned and dampened depending on the water content of the material. The changes in the
field are received by the sensor and evaluated by the processor. With the measurement of the above parameters and their evaluation, it is possible to determine moisture content and material density separately.
Using the above principle, the MWF 3000 measures the moisture content independent of the density. Depending on the sensor type, the field has
a penetration depth of 1½ to 4 inches.
The emitted microwaves do not cause heating or chemical reactions of the material.
