射流技术中频率的测量通常都是采用电气测量装置来进行的,例如采用示波器经带放大器的压力传感器来进行。这种测量虽然可精确地进行,但是所化费的代价却很大,同时,测量仪器的价格也是很贵的。尽管在实验室中采用这些仪器化费点钱是值得的,但对工业生产过程中的检测装置来说,要化费这么许多钱是不能设想的。下面所论述的线路使得射流元件能对频率
The measurement of the frequency in jet technology is usually carried out using electrical measuring devices, such as oscilloscopes with amplifier pressure sensors. Although this measurement can be accurately carried out, but the cost of the cost is great, at the same time, the price of measuring instruments is also very expensive. Although it is worthwhile to use these instrumental costs in laboratories, it is unimaginable to charge such a large amount of money for testing devices in industrial processes. The circuitry discussed below enables jetting elements to be frequency-dependent
