FIELD: measuring equipment.;SUBSTANCE: invention relates to the measuring equipment and can be used in the mass transfer processes studying and to determine the solvents in orthotropic capillary-porous materials diffusion coefficients in the paper, light, construction and other industries. Claimed method of the solvents diffusion coefficient in sheet orthotropic capillary-porous materials determining, which consists in the fact that in the studied sheet material developing the distributed in the solid phase solvent uniform initial content. Then placing the studied material on a flat substrate from the solvent-impermeable material. Waterproofing the material upper surface and, at the initial moment of time, performing the material under investigation pulsed wetting in a straight line by the constant performance solvent moving source in the orthotropic material given direction. Executing the galvanic converter electrodes in the form of straight line segments and placed on the pulsed wetting line both sides on the pulsed wetting straight, parallel lines, located at the same predetermined distance from it. Wherein the diffusion coefficient measurement is carried out under the condition of the galvanic sensor maximum signal Emax reaching in the experiment, making 0.75–0.95 of this signal Ee maximum possible value, corresponding to the solvent transition from the associated with the material under study solid phase region into the free state region. Fixing points in time τ1 and τ2, at which the galvanic sensor signals same values E1 and E2 are achieved from the range (0.7–0.9) Ee on the signal change with time curve ascending and descending branches, respectively. Diffusion coefficient calculation is performed by the formula: where x0 is the distance between the pulsed wetting line and the distance to the galvanic converter electrodes location line.;EFFECT: increase in the diffusion coefficient control accuracy.;1 cl, 2 tbl, 1 dwg
