Measurement Techniques Aims and scope

We consider a method of transferring the temperature of the triple point of water with an acoustic resonator configuration for measuring the Boltzmann constant. It is shown that the transfer of the temperature of the triple point of water in a resonator using a highly sensitive differentiator does not require the use of absolute means of measurement and implemented with uncertainty limited only by thermal noise. The method enables reducing uncertainty in the temperature transfer when measuring the Boltzmann constant, whose accurate measurement is necessary for transition to a new definition of the unit of temperature.
