The PG9607 is the next generation of absolute pressure piston gauge from Fluke Calibration. It supports the use of a 100 kg mass set to define gauge and absolute pressures from 11 to 500 kPa with a single piston-cylinder. The PG9602 is the next generation of absolute pressure piston gauge from Fluke Calibration. It includes multiple piston cylinder range options to support absolute or gauge pressure measurements from 12 kPa to 10 MPa. This piston gauge is designed for use as a true primary pressure reference in metrology and research institutes. Its performance is centered around a 50 mm piston-cylinder assembly with dimensional characteristics suitable for low-uncertainty dimensional traceability. The piston mounting post allows controlled clearance operation and reduced uncertainty on piston-cylinder temperature measurement. The new platform architecture promotes improved temperature stability around the piston-cylinder. PG9607 features AMH automated mass handling technology to allow fully automated testing in both gauge and absolute mode. Manual steps are removed from its 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 PG9607 a powerful calibration and research tool. PG9607 is the result of Fluke Calibration's extensive work with national metrology institutes (NMIs) to minimize pressure measurement uncertainty and years of supplying PG7000 piston gauges to NMIs and other top pressure metrology labs worldwide. PG9602/9607’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. Two decades ago, DH Instruments PG7000 family of piston gauges introduced the advantages of on-board sensing and monitoring technology, as well as other performance and ergonomic enhancements. The PG9000 platform adds several innovations to improve pressure measurements even further. The platform consists of a PG terminal, a piston gauge base and a new remote electronics module. The terminal is the user interface. It stores metrological component data, reports operating and ambient condition status and calculates pressure. The PG9000 piston gauge base supports automatic piston-cylinder rotation and mass handling, but all of the electronics to support the sensors and rotation control have been relocated to a remote electronics module. This architecture supports the best possible temperature stability at the base, even with prolonged vacuum operation, since any significant sources of heat are located away from the base. The PG9602/9607 mounting post has two integrated PRTs for reduced piston-cylinder temperature uncertainty. The PRTs are easily removed for calibration. A capacitance diaphragm gauge is included in the optional vacuum reference hardware for making residual vacuum measurements in absolute mode. PG9607 can also integrate the measurement output from virtually any user-supplied vacuum sensor. AMH automated mass handling technology is expanded on PG9602/9607 to provide gauge and absolute operation with up to a 100 kg mass load. Eliminating manual mass loading minimizes mechanical wear, improving mass stability. The automated mass handler operates inside the evacuated bell jar, so the time to release and draw a vacuum while changing masses between test points is eliminated. The sustained vacuum produces lower and more static residual vacuum values. Total test time and productivity are greatly improved, especially on absolute pressure tests. More importantly, full automation promotes highly consistent measurements and allows extensive tests with many test points that would be impractical to perform manually. And with the help of calibration management software like COMPASS® for Pressure, tests can be run fully unattended.
