DEVICE FOR TESTING DYNAMIC PRESSURE SENSORS Russian patent published in 2020 - IPC G01L27/00 

FIELD: instrument engineering.

SUBSTANCE: proposed invention relates to instrument making and testing equipment, in particular, to devices for dynamic testing (calibration) of pressure sensors used to determine characteristics of an air shock wave when testing real charges of high-energy condensed systems (ES) and articles based thereon, arranged on measuring beams of test sites. Device for calibration of dynamic pressure sensors consists of separate parallel installed tube modules for arrangement of charges of explosive substance, interconnected and arranged in common shell. Each module is an initiating waveguide. Initiating waveguides arranged in a common shell have the same length, with arrangement of open (output) ends of the waveguides in one plane. Total area of the open ends of the initiating waveguides is commensurate with the area of the membrane element of the tested pressure sensor.

EFFECT: applicability of a device for testing pressure sensors located directly in conditions of use thereof on measuring beams of a test site, and high accuracy of measurements while reducing risk of use.
