Abstract: FIELD: measuring equipment. 
     SUBSTANCE: invention relates to measuring equipment in the field of thermophysical properties of substances, materials and products and can be used in diagnosing the efficiency of industrial devices based on the principle of fluidization of granular material with an ascending gas flow, for example, kilns and fluidized bed dryers. The method consists in the fact that a solid body is introduced into the fluidized bed, a predetermined temperature difference between the solid and the fluidized bed is created, for which either forced cooling of the solid or its forced heating for a predetermined length of time is used. Simultaneously, the instantaneous temperatures of two predetermined areas of the surface are recorded, located at a predetermined base distance from each other, sequentially in the direction of the longitudinal flow of the fluidizing gas. The recorded temperatures determine the frequency of natural gravitational oscillations of the fluidized bed and the time shift between the same changes in the temperature of the given surface areas, and the required thermal diffusivity is found by calculation. The proposed method, in contrast to analogous methods, is easily implemented in the operating conditions of large industrial apparatuses, has a wider range of applications with a simultaneous high achievable measurement accuracy. 
     EFFECT: improves measurement accuracy and expanding the range of measured objects.
