PARKER派克電磁閥PHS510P-6-24V-L 1/8光纖水位計(jì)光纖水位計(jì)包括水位計(jì)傳感器部分和控制電路終端部分。其中，水位計(jì)傳感器部分采用光路耦合調(diào)節(jié)設(shè)備與光纜連接用于傳遞承載水位信息的光信號(hào)，控制電路終端部分采用激光調(diào)制技術(shù)，發(fā)送不同功能的調(diào)制激光信號(hào)，通過調(diào)制、對(duì)比與檢測(cè)，獲得水位的準(zhǔn)確信息。這一原理實(shí)現(xiàn)了全程光測(cè)量，在室外不使用任何帶電器件，可以杜絕靜電危害防止雷電擊毀。跟蹤式水位計(jì)又稱接觸式水位計(jì)，利用重錘上的電測(cè)針接觸水面發(fā)出電信號(hào)，使電機(jī)正轉(zhuǎn)或逆轉(zhuǎn)，隨時(shí)跟蹤水面點(diǎn)的位置，從而測(cè)定水位。一般在較陡岸坡上架設(shè)鐵管，懸錘和懸索在管道中升降，驅(qū)動(dòng)記錄或訊號(hào)裝置。鐵管進(jìn)水口需有沉沙和靜水設(shè)施。壓力式水位計(jì)它的工作原理是測(cè)量水壓力，推算水位。其特點(diǎn)是不需建靜水測(cè)井。
