產(chǎn)品介紹：
發(fā)射器和接收器之間沒有電氣連接，
雖然傳感器的安裝位置不會(huì)影響超聲波對(duì)射式傳感器的功能，
一個(gè)超聲波對(duì)射式傳感器由相互面對(duì)安裝的一個(gè)發(fā)射器和一個(gè)接收器組成。
超聲波對(duì)射式傳感器的工作原理是由發(fā)射器發(fā)射聲波
到接收器通過聲束被目標(biāo)物體打斷來檢測(cè)物體。
當(dāng)超聲波聲束因物體被衰減或者中斷后，接收器的輸出就切換開關(guān)狀態(tài)。
然而我們還是**當(dāng)傳感器垂直安裝時(shí)將發(fā)射器面朝上安裝以防止灰塵顆粒堆積。
發(fā)射器產(chǎn)生超聲波信號(hào)由接收器來接收評(píng)估。
產(chǎn)品特點(diǎn)：
響應(yīng)時(shí)間短
檢測(cè)物體很少出錯(cuò)因此適用在檢測(cè)困難的場(chǎng)合
兩個(gè)單元都需要接線安裝費(fèi)用較*
聲束單向傳播因此檢測(cè)范圍大
