本文讨论利用光纤技术实现远距离传输流量信号的问题。光纤系统能远距离传输检测仪表信号,特别不怕电磁场干扰。光纤传输检测系统由发讯机、光纤插件及收讯机组成。发讯机把市售LW系列涡轮流量变送器的电信号进行放大处理,继而推动发光管形
This article discusses the use of optical fiber technology to achieve the long-distance transmission of traffic signals. Optical fiber system can transmit instrumentation signals over long distances, especially not afraid of electromagnetic interference. Optical fiber transmission detection system consists of the transmitter, fiber optic plug-in and receiver components. Transmitter to market LW series of turbine flow transmitter electrical signal amplification, and then promote the light-emitting tube
