HGC-30000-AF is a special configuration of the OPG1 Hydraulic Pressure Generator/Controller and RPM3 A30000/A6000. The HGC-30000-AF was designed to optimize the testing and calibration of analog and digital pressure gauges and indicators in ranges from less than 1 000 psi (7 MPa) to 30 000 psi (200 MPa). This special configuration was selected by the United States Air Force as the next generation high pressure gauge calibration system for deployment in its Precision Measurement Equipment Laboratories (PMELs) throughout the world.
With OPG1, the operator effortlessly generates and adjusts pressure to set the device under test to its cardinal point. The RPM3 then precisely measures the actual pressure applied.
Interactive RPM3 embedded software automatically sets up the calibration procedure based on entry of the the DUT full scale and tolerance. It then steps the operator through the test, logging data and providing real time notification of in or out-of-tolerance conditions at each point. A foot pedal “ENTER” switch allows the operator to trigger readings hands free.

1Precision: Combined linearity, hysteresis, repeatability.
2 Stability: Change in zero and span, with use of AutoZ feature, over 6 months period for typical RPT used under typical conditions. As stability can only be predicted and varies from RPT to RPT, stability for a specific RPT should be established from experience.
3 Measurement Uncertainty: Maximum deviation of the RPT indication from the true value of the applied pressure including precision, predicted stability, temperature effect and calibration standard uncertainty of ± 0.005% of reading.
