Description
Automated primary pressure reference for absolute and gauge pressures to 10 MPa
PG9000 piston gauges are the next generation of absolute pressure piston gauges from Fluke Calibration. They are designed to enable metrology and research institutes to realize and disseminate exceptional fundamental pressure measurements.
Each PG9000 model supports the use of up to a 100 kg mass load in absolute and gauge pressure operation, creating a wide usable pressure range for each piston-cylinder and enabling more overlap of ranges for intercomparison.
Two PG9000 models are available:
PG9607 defines gauge and absolute pressures from 11 kPa to 500 kPa with a single piston-cylinder. It is designed
for use as a true primary pressure reference. Its performance is centered around a 50 mm piston-cylinder assembly with dimensional characteristics suitable for low-uncertainty dimensional traceability.
PG9602 includes multiple piston cylinder range options to support absolute or gauge pressure measurements from 12 kPa to 10 MPa.
Both models have mounting posts designed for greater confidence in the piston-cylinder temperature measurement.
The platform architecture also promotes improved temperature stability around the pistoncylinder.
PG9000 piston gauges feature AMH automated mass handling technology to allow fully automated testing in both gauge and absolute mode. Manual steps are removed from their operation, saving time and delivering metrological advantages. When AMH is coupled with automatic pressure control and computer software, repeated and extended
tests become practical, making PG9000 a powerful calibration and research tool.
PG9000 is the result of Fluke Calibration’s extensive work with national metrology institutes (NMIs) to minimize pressure measurement uncertainty and years of supplying piston gauges to NMIs and other top pressure metrology labs worldwide.
PG9607: Refined 50 mm piston-cylinder design
PG9607’s piston-cylinder assembly builds upon more than 15 years of design, manufacture and calibration of 50 mm piston-cylinders.
PC-9607-5 is a 5 kPa/kg piston-cylinder with a stationary piston and floating cylinder design. Improved manufacturing and testing methods are used to produce a very low distortion assembly.
The 50 mm piston-cylinder provides exceptional performance— up to 500 kPa with a 100 kg mass load. The PG9607
mounting post allows an independent controlled clearance pressure to be applied to the inside of the piston, thus predictably varying the size of the gap between the piston and cylinder for advanced study.
PG9602: Disseminate low uncertainty measurements to 10 MPa
PG9602 uses Fluke Calibration’s unique integrated piston-cylinder assemblies to measure pressures up to 10 MPa. These piston-cylinder modules have been used for years with PG7000 piston gauges and are now selected and tested for low uncertainty operation with up to 100 kg of mass with PG9602. The PG9000 platform design and high mass load produce a wide range and high performance piston gauge that is the ideal instrument to disseminate primary PG9607 measurements to higher pressure ranges with the lowest possible uncertainty.
