求翻译：This regulation system is to control the pressure balance between hydrogen and oxygen sides of the system. To use pressure difference transmitters installed on oxygen and hydrogen separators to measure the liquid level of two sides, give two signals of 4~20mA to PLC, there, they are compared and then through PID calcul是什么意思？ 待解决

本规例是以控制系统的压力平衡双方之间的氢及氧的系统。

这个章程系统是控制压力平衡在氢和系统之间的氧气边。 要使用压力区别发射机在氧气和氢分离器安装测量双方的液体水平，给4~20mA二个信号PLC，那里，他们通过PID演算被比较然后给信号电气体交换器，然后导致0.02~0.1Mpa气体信号控制氢管理者的开放性体会控制压力区别的目标在氢和氧气边之间的。

此规管制度是控制系统的氢气和氧气双方压力平衡。若要使用安装在氧和氢分离器差压变送器双方的液位测量，给两个信号的 4 ~ 20mA plc，那里，相比然后通过 PID 计算信号给电-气转换器，然后制作一个气体信号的 0.02 ~ 0.1 m p a 控制氢调节器实现控制目标的开放性高压氢气和氧气的双方之间的区别。
