FIELD: measurement technology. SUBSTANCE: device has two glass units. First glass unit mounts strain gage that functions to determine strain in center of unit and support reactions. Both surfaces of glass unit carry capacitive film sensors for measuring shock wave of air stream caused by deflection of first glass unit. Sensors are capable of simultaneous measurement of digital and integral values of dynamic pressure, determination of glass unit material characteristics, its integrity, as well as shock pressure built up by secondary fragments from first glass unit during dynamic loading. Device has preamplifier and low-frequency amplifier for strain gages. EFFECT: improved measurement accuracy. 1 dwg
