Description
Известные способы И3 мерени давлени газов, основанные на измерении или регистрации сигналов, поступающих с различных датчиков давлени , например с пьезоэлектрических, дифференциально-трансформаторных и других, не могут обеспечить безынерционного измерени .The known methods I3 for measuring the pressure of gases, based on the measurement or recording of signals from different pressure sensors, for example from piezoelectric, differential transformer, and others, cannot provide an inertialess measurement.
Предлагаемый способ, основанный на измерении интенсивности звука, распростран ющегос в газе, котора зависит от велич1 ны статического давлени газа, не имеет указанного недостатка.The proposed method, based on measuring the intensity of sound propagating in a gas, which depends on the magnitude of the static gas pressure, does not have this drawback.
На чертеже изображен электроакустический прибор дл осуществлени предлагаемого способа.The drawing shows an electro-acoustic device for carrying out the proposed method.
Электрический сигнал с генератора / звуковой частотыподаетс на пьезоэлектрический излучатель 2 звука, помещенный в герметизированный баллон 3. Баллон соединен с системой, давление в которой необходимо измерить. В этом же баллоне помещен электродинамический приемиик 4 звука, роль которого может выполн ть чувствительный микрофон. Сигнал от приемника подаетс на вход усилител 5, на выходе которого подключен измерительный прибор 6.An electrical signal from the generator / audio frequency is supplied to a piezoelectric sound emitter 2 placed in a sealed cylinder 3. The cylinder is connected to the system whose pressure is to be measured. The same cylinder contains an electrodynamic sound receiver 4, the role of which can be performed by a sensitive microphone. The signal from the receiver is fed to the input of the amplifier 5, the output of which is connected to the measuring device 6.
Предмет изобретени Subject invention
Способ измерени давлени газов, отличающийс тем, что, с целью достижени безынерционного измерени давлени , измер ют интенсивность звука, распростран ющегос в газе, котора находитс в линейной зависимости от его статического давлени .A method for measuring the pressure of gases, characterized in that, in order to achieve an inertialess measurement of pressure, the intensity of the sound propagating in the gas, which is linearly dependent on its static pressure, is measured.
