Typical Pressure Measurement Uncertainty Defined by an FPG8601 Force Balanced Piston Gauge (1.86 MB)

This technical note is written to help metrologists understand the influences on measurement uncertainty when using an FPG8601. It is also a predictive uncertainty analysis for measured pressure based on worse case or typical influences, product specifications of system measurements and typical environmental conditions which are defined in the following sections. The document briefly describes the traceability of the FPG8601, ways to reduce uncertainty and some information on the special challenges of measuring low pressure precisely.
