美國  百納（BANNA）分體式電子式數(shù)顯浮球液位計LE80A系列

原理，結(jié)構(gòu)

LE80A系列產(chǎn)品可同時具有模擬輸出和開關(guān)量輸出。磁性浮球隨液位的變化不斷觸發(fā)檢測桿中的磁簧開關(guān)，使得傳感器的總電阻發(fā)生變化，該信號被變送器轉(zhuǎn)換成標(biāo)準(zhǔn)電信號進行數(shù)字顯示并輸出4...20mA信號和開關(guān)信號。

特點

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