DEVICE FOR PRESSURE MEASUREMENT Russian patent published in 2010 - IPC G01L9/12 

FIELD: measurement equipment.

SUBSTANCE: invention is related to measurement equipment and may be used to measure distribution of fast-variable pressure fields on external surfaces. Device for measurement of pressure comprises multilayer pack of glass sheet, on both external surfaces of which there is a pack of capacitance sensitive elements mounted, source of explosion shock wave, unit of synchronisation, which consists of serially joined diaphragm, isolation resistor and power supply unit, outlet of which is connected to input of indicator, matching amplifier of charge, rating amplifier of voltage and indicator, output of capacitance sensitive elements via matching charge amplifier and rating voltage amplifier is connected to input of indicator. Besides on internal surfaces of multilayer pack of sheet glass there are packs of capacitance sensitive elements mounted, at the same time number of glass layers is represented by at least two layers of internal film, capacitance sensitive elements are symmetrically arranged along axes and diagonals of glass.

EFFECT: provision of high accuracy of measurement.
