Gas pressures from 100 kPa to 110 MPa (15 to 16,000 psi)
PG7202 is a member of the PG7000 family of reference level piston gauges that covers the range of high pressure gas up to 110 MPa (16,000 psi). Operating directly in gas avoids difficult to use liquid/gas separators that add uncertainty to the measurement process. PG7202’s gas operated, liquid lubricated piston-cylinder design overcomes the disadvantages of lubricating the piston-cylinder with gas at high pressure. Performance is not affected by gas cleanliness and piston drop rates are even lower than those typically found in hydraulic piston gauges.
PG7202 is combined with the GPC1 gas pressure controller to configure a complete manually operated calibration system with effort free gas pressure setting and adjusting. By substituting a PPCH-G automated pressure controller for GPC1 and adding on AMH-100 automated mass handler, PG7202 operation can be fully automated.
All PG7202 piston-cylinder modules can be delivered using Krytox®, a fluorinated synthetic oil, to lubricate the piston-cylinder for applications in which the system must be free of hydrocarbons.
Differential pressure at elevated line pressure
Two PG7202s can be used in combination to define low differential pressures at elevated line pressures. Contact Fluke Calibration for more information.
