Description
//. При этом усилитель 12 зырабатьгвает импульс напр жени VQ. Сдвиг по времени между импульсом УО и выходным сигналом 1/д датчика характеризует фазовый сдвиг термоанемометра . Задава различные обороты стола (т. е. различную частоту пересечени струи) можно получить фазочастотную характеристику прибора.//. In this case, the amplifier 12 triggers a voltage pulse VQ. The time shift between the pulse and the output signal of the 1 / d sensor characterizes the phase shift of the thermoanemometer. By setting different table turns (i.e. a different jet intersection frequency), one can obtain the phase-frequency characteristic of the device.
Таким образом, устройство, дава возможность получать отметки -времени входа термоанемометра 3 струю, позвол ет определить фазочастотную характеристику прибора. При этом фазовый сдвиг Дф 360°. ДГТ, где Т-период следовани импульсов, ДГ-сдвиг по времени между импульсом отметки УО началом выходного сигнала.Thus, the device, making it possible to obtain the marks of the input time of the hot-wire anemometer 3 jet, makes it possible to determine the phase-frequency characteristic of the device. In this case, the phase shift Df 360 °. DGT, where T is the period of the pulse following, DG is the time shift between the pulse of the EQ mark and the beginning of the output signal.
