ABSTRACT

This chapter focuses on drop-hammer, hydraulic pressure calibration device, according to the principle of quasi-static calibration; the shock wave pressure measurement system was calibrated. By using the appropriate data processing method, the low-frequency transmission characteristics of shock wave pressure measurement system was obtained. For the common method of shock wave pressure measurement-electrometric method, the mainly used pressure sensors are piezoresistive pressure sensors and piezoelectric pressure sensors. The chapter discusses the quasi-static calibration method of shock wave pressure measurement system. Quasi-static calibration, pressure sensor, comparison calibration and low-frequency transmission characteristics. Quasi-static is a method between static calibration and dynamic calibration. Dynamic calibration is commonly executed by shock tube. The sensitivity of the standard pressure monitoring system is transmitted by the standard calibration equipment. The transmission characteristic within 0-1000Hz shows substantially flat by obtaining the lowfrequency transmission characteristic of the shock wave pressure measuring system.
