Kulikov, V.A., Nikitin, K.A., Seletkov, S.G., Shelkovnikov, Y.K.

Abstract. Temperature gradient and the thermal conductivity of the soil is measured by the three-phase thermo-converter. Density of the heat flux is calculated by the Fourier’s law. The design of the sensor circuit and the measuring device are presented. The ability to measure of the heat flux density in the soil caused by the dissipation of heat from the heating duct, confirmed experimentally.

Keywords: temperature, thermal conductivity, heating, heat flow density in the soil
