style="text-indent:25px">限位開關(guān)、接近開關(guān)和光電開關(guān)是三種原理不同的傳感器，但作用一樣，都是檢測位置用的。那么讓我們看一下它們的區(qū)別； ①外形：限位開關(guān)一般是由一個(gè)明顯的動(dòng)作部位，而且該部位可以來回運(yùn)動(dòng)，運(yùn)動(dòng)角度不同，有的可以180度，有的只能90度。接近開關(guān)比較簡單，只是單獨(dú)的一個(gè)傳感器。有些光電開關(guān)的外形與接近開關(guān)一致，但有些則完全不同，需要有發(fā)射和接收兩部分組成，埃朗安全開關(guān)價(jià)格，埃朗安全開關(guān)價(jià)格。 ②檢測距離：限位開關(guān)需要與檢測物質(zhì)直接接觸。接近開關(guān)較近，一般檢測范圍一般是3-20mm，取決與傳感器，接近開關(guān)的檢測距離很大程度上與檢測頭的直徑有關(guān)，即檢測距離越大，需要的直徑越大。而光電開關(guān)的檢測距離一般很長，有些甚至可以達(dá)到幾米。這是一個(gè)明顯優(yōu)于接近開關(guān)的特點(diǎn)，但光電開關(guān)的原理與光有關(guān)，那么它就有一個(gè)明顯的缺點(diǎn)，埃朗安全開關(guān)價(jià)格，那就是容易受到水汽灰塵等影響，一旦水汽灰塵將檢測路線遮擋，傳感器就會(huì)失靈，而接近開關(guān)檢測金屬就沒有這個(gè)問題。埃朗安全開關(guān)價(jià)格</p><div

style="text-indent:25px">有一種開關(guān)，是利用很高的精確度和穩(wěn)定性能的壓力傳感器進(jìn)行操作的，那就是壓力開關(guān)。壓力開關(guān)不僅利用了壓力傳感器，還運(yùn)用了變送電路和**的對(duì)CPU模塊化信號(hào)進(jìn)行處理技術(shù)，對(duì)壓力進(jìn)行檢測、顯示壓力大小、警報(bào)以及控制壓力信號(hào)的輸出。壓力開關(guān)主要有兩種類型，一種是常開式的，而另一種則是常閉式的。壓力開關(guān)主要有四個(gè)特點(diǎn)，***個(gè)是，管螺紋接頭式和安裝結(jié)構(gòu)以及焊接銅管的安裝結(jié)構(gòu)十分靈活，并且在使用方面也是極其方便的，不需要額外的安裝來固定結(jié)構(gòu);第二個(gè)特點(diǎn)是，壓力開關(guān)具有插片式的連接方式和導(dǎo)線式的連接方式來供客戶進(jìn)行選擇;第三個(gè)特點(diǎn)是，壓力開關(guān)具有安全可靠的密封式的不銹鋼感應(yīng)器，客戶可以放心地使用;***一個(gè)是，在一定的壓力范圍之內(nèi)，客戶可以任意選擇一個(gè)壓力值讓壓力開關(guān)運(yùn)行。埃朗安全開關(guān)價(jià)格</p><div

style="text-indent:25px">光電開關(guān)是把發(fā)射和接受端之間的光線強(qiáng)弱變化轉(zhuǎn)換為電流的變化以達(dá)到探測的目的。由于光電開關(guān)輸出回路和輸入回路是電隔離（即電絕緣），所以可以再許多場合得到應(yīng)用。光電開關(guān)（光電傳感器）是光電接近開關(guān)的簡稱，它是利用被檢測物對(duì)光束的遮擋或反射，由同步回路選通電路，從而檢測物體有無的。物體不限于金屬，所有能反射光線的物體均可被檢測。光電開關(guān)將輸入電流在發(fā)射器上轉(zhuǎn)換為光信號(hào)射出，接收器再根據(jù)接收到的光線強(qiáng)弱或有無對(duì)目標(biāo)物體進(jìn)行探測，工作原理如圖所示。多數(shù)光電開關(guān)選的是波長接近可見光的紅外線光波型。</p><p

style="text-indent:25px">磁性開關(guān)是一種利用磁場信號(hào)來控制的線路開關(guān)器件，也叫磁控開關(guān)。磁性開關(guān)意思就是通過磁鐵來感應(yīng)的，這個(gè)“磁”就是磁鐵，磁鐵也有好幾種，市場上面常用的磁鐵有橡膠磁、永磁鐵氧體、燒結(jié)釹鐵硼等。開關(guān)就是干簧管了。干簧管是干式舌簧管的簡稱，是一種有觸點(diǎn)的無源電子開關(guān)元件，具有結(jié)構(gòu)簡單，體積小便于控制等優(yōu)點(diǎn)，其外殼一般是一根密封的玻璃管，管中裝有兩個(gè)鐵質(zhì)的彈性簧片電板，還灌有惰性氣體。平時(shí)，玻璃管中的兩個(gè)由特殊材料制成的簧片是分開的。當(dāng)有磁性物質(zhì)靠近玻璃管時(shí)，在磁場磁力線的作用下，管內(nèi)的兩個(gè)簧片被磁化而互相吸引接觸，簧片就會(huì)吸合在一起，使結(jié)點(diǎn)所接的電路連通。外磁力消失后，兩個(gè)簧片由于本身的彈性而分開，線路也就斷開了。德國梅爾壓力開關(guān)價(jià)格</p><p
