A simple method was proposed for estimation of the temperature of the hot wire of the thermal diffusion column. The method is based on Boyle-Charle’s law between the pressure change before and after turning on electricity and the radial temperature distribution which is determined by the thermal conductivity of the charged gas. The hot wire temperatures estimated by the present method agree well with those measured directly by the thermocouple and those measured through the glass window by the radiation pyrometer whose correction dial of emissivity was calibrated by the thermocouple. Separative analyses incorporated with the present temperature of the hot wire temperature predicted well experiments for nitrogen isotope separation. The present method is applicable for experiments with continuous feed and draw-offs, if the temperature distribution in the radial direction is not effectively affected by the feed and draw-offs.
