Description
координатной решетк;е 6. Выходной электрический коллектор 5 соединен с корпусом первичного преобразовател 1 посредством туннельного диода 7. Входной электрический коллектор 3.подключен к регистратору 8. Питание устройства осуществл етс от сети переменного тока, подаваемого на регистратор 8 и по коаксиальному кабелю 9, соедин ющему регистратор 8 с входной шиной 3.grid 6. e 6. The output electric collector 5 is connected to the body of the primary converter 1 by means of a tunnel diode 7. An input electric collector 3. is connected to the recorder 8. The device is powered from an AC network supplied to the recorder 8 and a coaxial cable 9, connecting recorder 8 with input bus 3.
Работа устройства осуществл етс следующим образом.The operation of the device is as follows.
Первичный преобразователь, включающий в себ чувствительный элемент и туннельный диод возбуждаетс на резонансной частоте, величина которой зависит от элекОомагнитных свойств q)eды, протекающей через преобразователь, в частности ,от усредненной диэлектрической проницаемости , котора определ етс соотношением объемов ЖИДКОЙ и газовой фаз в потоке, т.е. величиной сплощности измер емой среды. Отсчет величин резонансной частоты производитс в помощью подсоединенного к первичному преобразователю регистратора, например цифрового частотомера. Дл записи результатов измерений дополнительно можно использовать и циф ропечатающее устройство.The primary transducer, which includes the sensing element and the tunnel diode, is excited at a resonant frequency, the value of which depends on the electromagnetic properties of q) flow through the transducer, in particular, on the average dielectric constant, which is determined by the ratio of the volumes of the LIQUID and gas phases in the stream, those. the magnitude of the measured medium. The resonant frequency values are read using a recorder connected to the primary converter, for example a digital frequency meter. In addition, a digital printer can be used to record the measurement results.
Соединение выходного коллектора чувствительного элемента первичного преобразовател с его корпусом посредством туннельного диодаConnection of the output collector of the sensitive element of the primary converter with its body by means of a tunnel diode
с образованием собственно задающего генератора позвол ет реализовать систему измерени сплошности потока жидкости непосредственно в пр мой зависимости от величины резонансной частотыпервичного преобразовател без дополнительных электронных блоков.with the formation of the master oscillator itself, it makes it possible to implement a system for measuring the continuity of the fluid flow directly in direct dependence on the magnitude of the resonant frequency of the primary converter without additional electronic components.
