| Popis: | Designs of piezoelectric pressure gauges based on PZT-19 ceramics and equipment for testing and calibration of piezoelectric gauges are described. Tests of the developed piezoelectric transducers in a shock tube showed that their characteristics are stable in time, the sensitivity ranges from 5 to 50 mV/bar, the operating pressure range is up to 100 bar, and the frequency range with a high-resistivity matching amplifier is 10–5 × 105 Hz. The level of errors in measurements of pulse and oscillatory pressures is estimated as 5%. |
