“…In high-pressure measuring instruments, leakage prevention design is essential. Thus to tackle the problem, a connection assembly is used to connect the pressure transducer to the highpressurised fluid line to create a leak-proof design [26][27][28]. This design uses a high-strength cone (stainless steel) between the connector and transducer assembly.…”

Over the past few decades, the rapid and expanding usage of high-pressure technologies in science and engineering has prompted researchers to focus on developing better instruments and technologies with improved measurement uncertainties for various applications. Such efforts resulted in the development of new and advanced measurement techniques and standards to address calibration challenges and provide traceability to users. In the present study, an indigenous strain gauge-type pressure transducer has been designed, developed, tested, and calibrated for pressure measurements up to 1000 MPa. The sensing element's cylindrical shape was used, providing a cost-effective and straightforward approach for designing a pressure transducer over a wide pressure range. It also ensures a leak-proof and locked connection to the external environment, with no over-constrained contacts. The calibration and performance checking of the pressure transducer has been carried out using the national primary pressure standard with the internationally accepted calibration procedure. The transducer response under pressure is highly linear during its performance evaluation. As a result, the transducer performs satisfactorily within the reasonable measurement uncertainty of 0.5% of the full scale. The pressure transducer developed may help trace the user industries and calibration laboratories in the high range of pressure measurement and serve as a pressure transfer standard.

“…The development of the primary metrology of the very high pressures has recently been revived in Europe as well which led to a cooperative research project [4], [5] and a novel interlaboratory comparison in 1 GPa range (EURAMET.M.P-S14) [6], [7].…”

The expansion of the high technology leads to the increasing demands for the calibration services in the extremal pressure ranges, both vacuum and high gauge pressure in liquid medium. The presentation will deal with the second one, focusing on the solution chosen by the Czech Metrology Institute (CMI) to improve its services in the range of gauge pressure from 0.5 GPa to 1 GPa. A new high-pressure standard will be described, and its first evaluation outlined.

“…These terms can be solved either by approximation with opportune assumptions [25], or numerical calculations [26][27][28]. Among the numerical techniques, the finite element (FE) method has been proven to be efficient and accurate [27,[29][30][31] and widely applied for characteristic studies on CC piston gauges [28,32,33] as well as new device development [34].…”

We utilized numerical methods to analyze the characteristics of the piston-cylinder assembly of a controlled-clearance piston gauge. The piston gauge was able to measure liquid pressure from 100 MPa to 1500 MPa with relative expanded uncertainty of 0.02 % (k = 3). We established a finite element model to solve the stress and strain of the structural problem. The effective areas were calculated based on Dadson’s formula using the converged solutions of the clearance and the pressure distribution within the distorted piston-cylinder engagement gap that were iteratively determined by the finite element model and a fluid mechanics model with pressure-dependent fluid’s properties. Results were compared to the effective areas calculated by the modified Heydemann-Welch model based on experimental data, and the relative differences were less than 0.02%. We found sharp declines of the clearance and pressure distribution near the exit of the piston-cylinder engagement gap, which may lead to wearing during long-time operation at high pressures. Numerical results indicated non-linear relationship between jacket pressure and the cubic root of piston fall speed, which was traditionally considered as linear. The stall jacket pressure obtained by cubic (instead of linear) fitting extrapolation was found more close to the ones determined directly by the finite element model. Numerical results also found non-linear relationships among jacket pressure, measuring pressure, jacket pressure distortion coefficient.
