VEGAMIP 系列微波光柵適用于非接觸式限位檢測(cè)各種液體和固料的物位。也可以透過(guò)容器壁檢測(cè)高純度液體。 對(duì)于固料，微波光柵也適用于重型和起塵介質(zhì)或在輸送帶上探測(cè)回堵現(xiàn)象。

  

測(cè)量原理 

微波光柵如同一個(gè)光柵一樣發(fā)揮作用： 一旦介質(zhì)中斷發(fā)射器和接收器之間的微波射線，則信號(hào)便被衰減。 這一變化被接收器測(cè)得并被它轉(zhuǎn)變成一個(gè)開(kāi)關(guān)信號(hào)。
 

優(yōu)點(diǎn)
利用該方法可以在無(wú)需接觸介質(zhì)的情況下測(cè)得極限物位。 這樣在傳感器上便不會(huì)產(chǎn)生污染、附著物和磨損，由此可以實(shí)現(xiàn)無(wú)磨損和免維護(hù)的連續(xù)運(yùn)行。
