Microwave moisture sensor

 

 

      Within the framework of the project we have designed the open resonator for moisture estimation of bulk solids (sand) and concrete. The properties of open resonator (fig. 1) depend on dielectric permeability and dielectric loss tangent of medium. On fig. 2  the moisture dependences of resonance frequency and Q-factor of resonance system are shown. Test medium is sand.
