DEVICE FOR MEASURING PARAMETERS OF IMPULSE PRESSURE Russian patent published in 2007 - IPC G01L23/10 

FIELD: measuring equipment engineering, in particular, electrical and optical measurements of parameters of impulse mechanical loads in vibro-acoustics and physics of blast waves, including during electric detonation of conductors and effect of intensive radiation or corpuscular rays on a substance.

SUBSTANCE: device for measuring parameters of impulse pressure contains sensitive element in form of flat piezo-element with input and output electrodes on two opposite surfaces, perpendicular to polar axis of piezo-element, and a measuring line. New in device is that input and output electrodes are electrically directly connected to each other, while measuring line is made in form of optical channel for measuring parameters of movement of surface of piezo-element with output electrode.

EFFECT: increased resistance of device to interference from electromagnetic pickups, expanded capacity band and area of possible use of device, and also increased information capacity of measurements.
