Изобретение относитс к способам определени содержани материала в емкости, например песка :в бункере.This invention relates to methods for determining the content of material in a container, for example, sand: in a silo.
Известен -способ определени содержани материала в емкости, включающий возбуждение вынужденных акустических колебаний с последующим измерением их частоты. Известный способ трудоемок, а погрешности измерений прИ его применепии достигают значительной величины.A known method for determining the content of material in a container, including the excitation of forced acoustic oscillations with the subsequent measurement of their frequency. The known method is time-consuming, and the measurement errors in the field of its application reach a significant value.
Цель изобретени - упрощение и повышение точности измерений.The purpose of the invention is to simplify and improve the accuracy of measurements.
Дл этого по предлагаемому способу вынужденные акустические колебани возбуждают в свободном от .контролирумого материала воздухе емкости до возникновени в нем резонансных колебаний, частоту которых измер ют и 1ПО ней суд т о количестве наход щегос в емкости материала.To do this, according to the proposed method, forced acoustic oscillations excite a capacitance free of controlled material in the air before resonant oscillations occur in it, the frequency of which is measured and 1PO of it judges the amount of material in the capacitance.
На чертеже изображено устройство, реализующее предлагаемый способ.The drawing shows a device that implements the proposed method.
Оно содержит генератор 1, кабель 2, акустический излучатель 3, мембрану 4, бункер 5, прибор 6, контролирующий режим работы генератора .It contains a generator 1, a cable 2, an acoustic emitter 3, a membrane 4, a hopper 5, a device 6 controlling the mode of operation of the generator.
Способ осуществл ют следующ-им образом.The method is carried out as follows.
От генератора 1 переменной частоты по соединительному кабелю 2 электрический ток подаетс на акустический излучатель 3, мембрана 4 которого находитс в контакте с залюченным в свободном от -материала пространстве -бункера 5. Частоту генератора измен ют до по влени в заключенном в свободном пространстве бункере резонансных влеНИИ , которые могут быть легко обнаружены, -например, при помощи любого прибора 6, контролирующего режим работы генератора, питающего акустический излучатель. В момент совпадени частоты генератора с частотойFrom a variable frequency generator 1, a connecting cable 2 is supplied to an acoustic emitter 3, the membrane 4 of which is in contact with the capacitor 5 in the free space of the material. The frequency of the generator is changed to the appearance of a bunker in the free space of the resonator. which can be easily detected, for example, with the help of any device 6 that controls the mode of operation of the generator feeding the acoustic emitter. At the time of coincidence of the frequency of the generator with the frequency
собственных колебаний заключенного в свободном от контролируемого материала пространстве бункера воздуха режим отбора -мощности от генератора резко измен етс , что в данном случае и -фиксируетс прибором 6,natural oscillations of the air bunker prisoner in the air bunker free from the material being monitored, the selection mode of the power from the generator changes dramatically, which in this case is fixed by the device 6,

Предмет изобретени Subject invention
Способ определени содержани материала в емкости, включающий возбуждение вынужденных акустических колебаний с последующим измерением их частоты, отличающийс тем, что, с целью упрощени и повышени точности измерений, вынужденные акустические колебани возбуждают в свободном от контролируемого материала воздухе емкост до возникновени в нем резонансных колебаний , частоту которых изме|р ют и по ней суд т о количестве -наход щегос в емкости матер и ал а.The method of determining the content of material in the vessel, including the excitation of forced acoustic oscillations with the subsequent measurement of their frequency, characterized in that, in order to simplify and improve the measurement accuracy, the forced acoustic oscillations excite the air in the free air from the material being monitored before the occurrence of resonant oscillations in it. which are measured and judged by it about the amount of mater and al.
