電子式數(shù)顯浮球液位計(jì)LE80系列

原理，結(jié)構(gòu)

LE80系列產(chǎn)品可同時(shí)具有模擬輸出和開(kāi)關(guān)量輸出。磁性浮球隨液位的變化不斷觸發(fā)檢測(cè)桿中的磁簧開(kāi)關(guān)，使得傳感器的總電阻發(fā)生變化，該信號(hào)被變送器轉(zhuǎn)換成標(biāo)準(zhǔn)電信號(hào)進(jìn)行數(shù)字顯示并輸出4...20mA信號(hào)和開(kāi)關(guān)信號(hào)。

特點(diǎn)

數(shù)字顯示，壽命長(zhǎng)，可用于對(duì)液位的限位監(jiān)控或連續(xù)監(jiān)控?？奢p松實(shí)現(xiàn)高低液位報(bào)警和泵控制功能。開(kāi)關(guān)值和模擬量值可自由設(shè)定。
