AUTONOMOUS PRESSURE METRE Russian patent published in 2009 - IPC G01L23/26 

FIELD: physics, measurement.

SUBSTANCE: invention is related to measurement equipment and may be used to detect profile of shock wave and measure field of excessive pressure on specified surface. Autonomous metre of pressure comprises information detector and unit of measurement, which consists of analog-digital converter and unit of memory, n programmable amplifier of charge, microcomputer, setter of reference voltages, unit of environmental parametres and current time, unit of control, supervisor, radio transceiver, besides information sensor comprises n sensors of excessive pressure, analog-digital converter is n-channeled, group of outlets of n detectors of excessive pressure via n programmable amplifiers of charge are connected to the first group of n inlets of analog-digital converter, digital outlet of which is connected to the first inlet of microcomputer, the first outlet of which is connected to inlet of memory unit, and second outlet - with radio transceiver inlet, the first outlet of control unit is connected to the second inlets of n programmable amplifiers of charge, and the second outlet - with inlet of setter of reference voltages, outlet of which is connected to the second inlet of analog-digital converter, outlet of supervisor is connected to the second inlet of microcomputer, outlet of memory unit is connected to the third inlet of microcomputer, outlet of unit of environmental parametres and current time is connected with the fourth inlet of microcomputer, inlet of com-port is connected to microcomputer, and its outlet is the second outlet of measurement unit, outlet of radio transceiver is the first outlet of measurement unit.

EFFECT: higher information value of pressure metre, higher accuracy of measurements, and also provision of convenience in operation due to contactless pickup of readings.
