How does MoistScan® differ from other online moisture meters?
A. The MoistScan® employs a patented technique that differentiates it from its competitors. Using a combination of attenuation/phase shift of the microwave signal and dielectric discrimination techniques, the MoistScan® will provide the end user with consistently reliable results. EXAMPLE: Fine coal typically has a dielectric constant of between 2 to 4 compared to the dielectric constant of water of 80.4. The variation of water within the coal results in a large variation in the combined dielectric constant which may then be measured by monitoring the change in the microwave signal. Both the change in velocity (phase shift) and the change in power (attenuation) of the received microwave signal are affected by the change in the dielectric constant of the analysed material. The microwave measurement is affected mainly by the excitation of free moisture molecules rather than many other types of materials, due to the extremely high dielectric constant of water.
