A METHOD OF TRACEABILITY FOR A FPG8601 FORCE BALANCED PISTON GAUGE TO DEFINE PRESSURES IN THE RANGE FROM 1 PA TO 15 KPA IN GAUGE AND ABSOLUTE MEASUREMENT MODES
Rob Haines, Michael Bair
Abstract:
The FPG8601 has become an important reference for many primary measurement laboratories in a pressure range from approximately 1 Pa to 15 kPa in both gauge and absolute measurement modes. The FPG8601 measurement range spans the gap between the traditional measurement regimes of "pressure" and "'vacuum", a range where other primary pressure standards either do not exist or do not have uncertainties sufficient to support the FPG8601 traceability. The limitations of available primary standards create a challenge for FPG8601 users needing to define traceability in this range. This paper suggests a method of maintaining traceability using force, dimensional and primary pressure measurements in a manner different from that normally used for traditional "floating" piston gauges.
