In dynamic pressure measurement phenomena, dynamic pressure calibration of the measurement chain including a pressure sensor, signal conditioning amplifier and data acquisition part is required. A drop mass dynamic calibration machine which is used for the dynamic calibration in hydraulic media was designed and developed. This study presents a research study and measurement results on the dynamic calibration of pressure transducers by using the newly developed machine.

“…Metrological traceability to the International System of Units (SI) requires the development of appropriate primary standards for dynamic measurements of pressure [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. The aperiodic shock tube pressure generators show a potential to provide SI-traceable dynamic calibrations for pressure sensors [ 17 , 18 , 19 , 20 , 21 ].…”

Technological progress demands accurate measurements of rapidly changing pressures. This, in turn, requires the use of dynamically calibrated pressure meters. The shock tube enables the dynamic characterization by applying an almost ideal pressure step change to the pressure sensor under calibration. This paper evaluates the effect of the dynamic response of a side-wall pressure measurement system on the detection of shock wave passage times over the side-wall pressure sensors installed along the shock tube. Furthermore, it evaluates this effect on the reference pressure step signal determined at the end-wall of the driven section using a time-of-flight method. To determine the errors in the detection of the shock front passage times over the centers of the side-wall sensors, a physical model for simulating the dynamic response of the complete measurement chain to the passage of the shock wave was developed. Due to the fact that the use of the physical model requires information about the effective diameter of the pressure sensor, special attention was paid to determining the effective diameter of the side-wall pressure sensors installed along the shock tube. The results show that the relative systematic errors in the pressure step amplitude at the end-wall of the shock tube due to the errors in the detection of the shock front passage times over the side-wall pressure sensors are less than 0.0003%. On the other hand, the systematic errors in the phase lag of the end-wall pressure signal in the calibration frequency range appropriate for high-frequency dynamic pressure applications are up to a few tens of degrees. Since the target phase measurement uncertainty of the pressure sensors used in high-frequency dynamic pressure applications is only a few degrees, the corrections for the systematic errors in the detection of the shock front passage times over the side-wall pressure sensors with the use of the developed physical dynamic model are, therefore, necessary when performing dynamic calibrations of pressure sensors with a shock tube.

“…Dynamic measurements of pressure play a key role in manufacturing, process control, product testing, internalcombustion engines, and in safety-related measurements [1][2][3][4][5][6][7][8]. For instance, to ensure the safety of the user of powderactuated tools or firearms the maximum safe pressure during firing of the tool or gun must not be exceeded.…”

We have characterized the measurement uncertainty of a setup for the dynamic measurement of pressure pulses with amplitudes in the low kbar range and with millisecond duration. The uncertainty is closely proportional to pressure, with a magnitude of 0.34% (coverage factor k = 1). In particular, we treat the safety-critical application of measuring the pressure inside an ammunition cartridge during firing, where a target uncertainty of 3% has been set by the Permanent International Commission for the Proof of Small Arms.
