Передача температуры тройной точки воды на акустический резонатор методом сравнения
Abstract
Detailed analysis of the method used to transfer the temperature value from the water triple point cell (TPW) to the acoustic resonator of the installation for measuring the Boltzmann constant is presented. The transfer of the temperature value from TPW to the resonator is performed, using a highly sensitive differential sensor which however can not be considered as the absolute measuring instrument. The method is proved to allow the transfer with the uncertainty limited only by thermal noises. The method enables to lower uncertainty of the transfer of Boltzmann constant measuring results, which is needed for redefining the Kelvin unit in terms of the Boltzmann constant.
