In order to detect the moisture content quickly and accurately
a set of microwave measurement system is designed.The working principle of the system is based on the relationship between the power variation
attenuation and moisture when the microwave penetrates the object moisture content.The working center frequency is 10.5 GHz.It is insensitive to temperature variation
salt melted content in the water and the material color.Accuracy is ±1 %;The measurement range of moisture content is from 5 %
3
0 %;and its radiating power is 10 mW.The system is used for the measurement of samples with certain thickness such as cardboard and cloth.
