To develop electrically based pressure standards, we measured the dielectric permittivity of helium εHe(p,T) and argon εAr(p,T) using two independent techniques (quasispherical microwave cavities and cross capacitors). At 7 MPa, the microwave results for helium differ from NIST’s pressure standards by (18±37)×10−6.

Abstract
To develop electrically based pressure standards, we measured the dielectric permittivity of helium εHe(p,T) and argon εAr(p,T) using two independent techniques (quasispherical microwave cavities and cross capacitors). At 7 MPa, the microwave results for helium differ from NIST’s pressure standards by (18±37)×10−6.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
