Interpretive Summary:

Technical Abstract: Research involving critical fluids is a sub-discipline of high pressure technology and should also encompass the evaluation of components (pressure gauges, flowmeters, pumps, etc.) that are routinely used in measuring experimental data and mechanically conducting extractions or reactions. A unique system has been developed at NCAUR for performing these tasks, which can include the calibration of various types of pressur gauges, determining the leak status of high pressure valves, or testing the efficacy of repaired pumps or compressors used for fluid delivery. The pressure test bench is capable of generating reproducible pressures to 20,000 psi and features both low and high calibration gauges which are routinely used in the NCAUR High Pressure Laboratory. The bench is capable of both producing and/or receiving pressure signals, allowing it to be used for many types of pressure calibration and testing for fluid leakage. A description of the design, construction, and use of this pressure test bench will be presented, including provision for automatic data recording of pressure, flow, and other variables which impact on using critical fluids in a high pressure laboratory.
