P+F超聲波開(kāi)關(guān)采用非接觸探測(cè),在6cm到10m范圍可測(cè)量至毫米。它的原理是:超聲波接近開(kāi)關(guān)發(fā)出超聲波脈沖,通過(guò)接收反射波計(jì)算出距離并轉(zhuǎn)換輸出信號(hào)。它有可達(dá)10m的遠(yuǎn)距離辨別精度達(dá)幾毫米級(jí),很好的重復(fù)性,并只需很少的維護(hù)。對(duì)于惡劣的工業(yè)環(huán)境中常見(jiàn)的灰塵和污物，其性能不受影響。對(duì)于液體的探測(cè)精度與固體顆粒或粉末相同,因此超聲波接近開(kāi)關(guān)適用范圍很廣,可用于液面、定位、限位或堆垛探測(cè)控制。
