Description
как частотно залаюший элемент генератора . Клеммы подключены к трехжильному кабелю св зи.as the frequency element of the generator. Terminals are connected to a three-wire communication cable.
Устройство работает следукидим образом .The device works in the following way.
По проводу питани подаетс команда) перевод ща дешифратор, соответственно и реле, в рабочий либо калибровочный режим. В рабочем режиме пьезоэлемент через предусилитель подключен к выходному проводу, а генератор выключен. В калибровочном режиме генератор включен, и его сигналы через тот же предусилитель поступают в выходной провод, а пьезоэлемент действует как врем задаюшнй блок генератора.A command is sent over the power wire to transfer the descrambler, respectively the relay, to the operating or calibration mode. In the operating mode, the piezoelectric element through the preamplifier is connected to the output wire, and the generator is turned off. In the calibration mode, the generator is turned on, and its signals through the same preamplifier enter the output wire, and the piezoelectric element acts as a time given generator unit.
По амплитуде и частоте выходных сигналов в режимекалибровки суд т об исправности пьезоэлемента, предусилител и кабел св зи.The amplitude and frequency of the output signals to the calibration mode are used to judge the condition of the piezoelectric element, the preamplifier and the communication cable.
Амплитудное значение выходного напр жени генератора используетс дл калибровки чувствительности предусили- тел . Огклоиени частоты генератора от начального значени используютс The amplitude value of the output voltage of the generator is used to calibrate the sensitivity of the preamplifier. Ogloieni frequency generator from the initial value used
дл контрол изменений чувствительности пьезоэлемента. Отклонени частоты генератора от начального значени использукггс дл контрол изменений чувствительности или глубины погружени пьезоэлемента. Вместо реле в преобразователе могут быть использованы такжеto control changes in the sensitivity of the piezoelectric element. Deviation of the generator frequency from the initial value is used to control changes in the sensitivity or immersion depth of the piezoelectric element. Instead of relays in the converter can also be used
