Description
(54) УЛЬТРАЗВУКОВОЙ СИГНАЛИЗАТОР УРОВНЯ(54) ULTRASOUND LEVEL SIGNALIZER
Пьезопреобраэователь 2 возбуждаетс на резонансной частоте радиальной моы колебаний. При этом размер радиуса дна стакана подобран так, что в нем образуетс сто ча волна. Цииндрический пьезопреобразователь 3 прикреплен к дну стакана в месте макЬимального значени амплитуды его колебаний и поэтому напр жение на его электродах достигает большой величины .Piezo transducer 2 is excited at the resonant frequency of a radial oscillation wave. At the same time, the size of the radius of the bottom of the glass is selected so that a standing wave forms in it. The cyanic piezoelectric transducer 3 is attached to the bottom of the glass in the place of the maximum value of its oscillation amplitude and therefore the voltage across its electrodes reaches a large value.
Когда жидкость касаетс дна стакана , увеличиваютс акустические потери , резко уменьшаетс амплитуда колебаний дна стакана и соответственно напр жение на электродах пьезопрёобразовател 3, подключенного к блоку сигнализации 5, т. е. сигнализатор выдает сигнал.When the liquid touches the bottom of the glass, the acoustic losses increase, the oscillation amplitude of the glass bottom decreases and the voltage on the electrodes of the piezoelectric transducer 3 connected to the alarm unit 5, respectively, i.e., the detector gives a signal.
Така конструкци позволит повысить чувствительность и точность работы сигнализатора.Such a design will increase the sensitivity and accuracy of the detector.
