Abstract
A new version of a noise thermometer has been realized at the Istituto di Metrologia Gustavo Colonnetti (IMGC) to determine the thermodynami c temperature of the melting and freezing points of copper. Low-noise, low-input-capacitance amplifiers, cross-correlating amplifiers and sp ecially shielded resistive sensors were designed, realized, and tested . They are described in this work and their relevant features are disc ussed as well as the problems associated with EMI and electrical leaka ges at high temperatures.
