METHOD FOR MEASUREMENT OF HUMIDITY OF CAPILLARY-POROUS MATERIALS

摘要

Area: measuring engineering. Method for measurement of humidity includes measurement of phase shift between the voltages on sample element and indicator that are connected in sequence, at that additionally one measures current that flows through the sample element and respective dielectric permittivity of wet material. Technical result: possibility of increase of accuracy of measurements is provided due to removal of error caused by non-stable mass of material under investigation in volume of capacitor indicator and at absence of coefficient of proportionality between humidity and the values being measured.
