机友·柯姆Pi仪设计新颖,结构简单,携带方便。它可以在拆装不便或无法拆装、搬运的条件下使用,弥补了某些进口设备搬运困难的不足。Pi仪主机共有五个专用微处理器,分别用于dV表计算,平均循环处理、主处理、Pmax、dPmax处理和输出控制等。另外总线上还挂有CX-4800绘图仪及显示器,并设有标准RS232C接口,以便将其测量数据送往其他计算机作进一步处理。除主机外整个测量系统还包括压电传感器,高性能电荷放大器(PCA内燃机测试专用)和曲轴转角信号发生器(CDM)等主要功能由于该仪器配用了多个专用微处理器(型号6502A),可以迅速方便地给出以下有关缸内压力变化的测量
Jianyou Ke Mu Pi instrument design, simple structure, easy to carry. It can be inconvenient disassembly or disassembly, handling conditions used to make up for the lack of handling some of the difficulties of imported equipment. Pi instrument host a total of five dedicated microprocessors, respectively, for the dV table calculation, the average cycle processing, main processing, Pmax, dPmax processing and output control. In addition, the CX-4800 plotter and monitor are hung on the bus, and a standard RS232C interface is provided so that the measurement data can be sent to other computers for further processing. In addition to the host computer, the entire measurement system includes the main functions of piezoelectric sensors, high-performance charge amplifiers (PCA for internal combustion engine testing) and crankshaft angle signal generator (CDM). Since the instrument is equipped with multiple dedicated microprocessors (Model 6502A) , You can quickly and easily give the following measurement of changes in cylinder pressure
