发明名称 METHOD FOR MEASURING MOISTURE CONTENT OF CAPILLARY-POROUS MATERIAL
摘要 The proposed method for measuring moisture content of capillary-porous material consists in determining the dielectric permittivity of the material attwo different frequencies of the test signal, measuring dielectric loss tangent for the material at the said frequencies, determining the difference between the dielectric loss tangent values at the said frequencies, and using the data so obtained for determining the moisture content by a specified equation. The present invention provides a possibility to increase measurement accuracy by excluding the error that is caused by the instability of dielectric losses in material.
