Ivanova, A. Pokhodun, I. Pokhodun] An analytical solution is presented for the problem of the temperature distribution over the height of the temperature channel of platinum resistance thermometers during their calibration at the reference points of MTSh-90. Estimates are made of the distortions of the initial linear temperature distribution on the outside of the channel with the transition to its inside surface. Miniature thermometers are used to measure temperature distribution over the height of the channel in triple-point cells. The measurements show that the temperature gradient at the bottom of the channel (regardless of whether or not the miniature thermometer is present) does not conform to the calculated distribution due to the effect of the hydrostatic pressure exerted by the column of the test substance on the phase-transformation temperature.
