AbstractNIST desires to develop a standard of pressure in the range of 0.3Mpa to 10 Mpa based on measurements of the dielectric constants of gaseous helium and argon. This requires capacitance measurements having a better linearity than can be made with any currently available product. It is proposed that the design of what is currently the most precise commercial capacitance bridge be modified to improve its linearity by at least an order of magnitude. Resolution, stability and temperature coefficient are also to be improved.
