PRESSURE REGISTRATOR AND SPEED OF SHOCK WAVE Russian patent published in 2018 - IPC G01L23/26 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a measuring technique and can be used to determine the pressure and velocity of a shock wave. Pressure and shock velocity registrar contains an information sensor, n programmable charge amplifiers and a measurement unit that consists of an analog-to-digital converter and a memory unit, microcomputer, reference voltage master, environmental and current time unit, control unit, supervisor, radio transceiver, information sensor consists of n overpressure sensors, the analog-to-digital converter is n-channel, a group of outputs of n gage pressure sensors through n programmable charge amplifiers are connected to the first group of n inputs of the analog-to-digital converter whose digital output is connected to the first input of the microcomputer, first output of which is connected to the input of the storage unit, and the second output is connected to the input of the radio transceiver, first output of the monitoring unit is connected to the second inputs of n programmable charge amplifiers, and the second output is connected to the input of the reference voltage master, the output of which is connected to the second input of the analog-to-digital converter, the output of the supervisor is connected to the second input of the microcomputer, output of the memory unit is connected to the third input of the microcomputer, the output of the environmental parameters block and the current time is connected to the fourth input of the microcomputer, the com-port input is connected with the output of the microcomputer, and its output is the second output of the measurement unit, the output of the radio transceiver is the first output of the measurement unit, additionally, a transceiver, a personal computer, n pressure sensors (n≥4) of the information sensor are located perpendicular to the direction of motion of the front of the shock wave at equal R distances from each other, the transceiver input is connected to the first output of the measurement unit, the output of the transceiver is connected to the input of the personal computer.

EFFECT: technical result in the implementation of the claimed invention is the expansion of the functionality of the pressure meter due to the additional determination of the shock wave velocity and the dependence of the change in the velocity of the shock wave from the distance to the source of its origin.
