光電(dian)(dian)(dian)(dian)傳(chuan)(chuan)感(gan)器是(shi)采(cai)用光電(dian)(dian)(dian)(dian)元(yuan)(yuan)件作為檢(jian)測(ce)(ce)(ce)元(yuan)(yuan)件的(de)傳(chuan)(chuan)感(gan)器.它首先把被測(ce)(ce)(ce)量的(de)變(bian)(bian)化(hua)轉換(huan)(huan)成(cheng)光信號的(de)變(bian)(bian)化(hua),然后借助光電(dian)(dian)(dian)(dian)元(yuan)(yuan)件進(jin)一(yi)步(bu)將光信號轉換(huan)(huan)成(cheng)電(dian)(dian)(dian)(dian)信號.光電(dian)(dian)(dian)(dian)傳(chuan)(chuan)感(gan)器一(yi)般由光源、光學通(tong)路和光電(dian)(dian)(dian)(dian)元(yuan)(yuan)件三(san)部分組成(cheng).光電(dian)(dian)(dian)(dian)檢(jian)測(ce)(ce)(ce)方法具有精度高、反應(ying)快、非接觸等優點,而且可測(ce)(ce)(ce)參數多,傳(chuan)(chuan)感(gan)器的(de)結構簡單,形式(shi)靈活多樣,因此,光電(dian)(dian)(dian)(dian)式(shi)傳(chuan)(chuan)感(gan)器在檢(jian)測(ce)(ce)(ce)和控制中應(ying)用非常(chang)廣泛(fan).

光(guang)電傳感(gan)器(qi)是各種(zhong)光(guang)電檢(jian)測系統中實現(xian)光(guang)電轉換的關(guan)鍵元件,它(ta)是把光(guang)信號（紅外(wai)、可見及紫外(wai)光(guang)輻射）轉變(bian)成為電信號的器(qi)件.

wenglor光電傳感器是什么光電傳感器特點

優點(dian)一：檢測距(ju)離(li)長。

我(wo)們(men)知道，市場上大部分的(de)傳(chuan)感器其(qi)檢測(ce)距(ju)離(li)都是(shi)十分有限的(de)。而新型(xing)的(de)光電傳(chuan)感器在對射型(xing)中保留10m以上的(de)檢測(ce)距(ju)離(li)等，便能實現其(qi)他檢測(ce)手段。

優點二：對檢(jian)測物體(ti)的限制少。

由(you)于光電傳(chuan)(chuan)感器以(yi)檢測(ce)(ce)物體引起的遮光和(he)反(fan)射為檢測(ce)(ce)原理(li)，所(suo)以(yi)不(bu)像接(jie)近傳(chuan)(chuan)感器等將檢測(ce)(ce)物體限定在金屬范(fan)圍內，它可對玻(bo)璃、塑(su)料、木(mu)材、液體等幾乎所(suo)有物體進行檢測(ce)(ce)。

優點三：響(xiang)應時間短。

大家都知(zhi)道(dao)，光(guang)(guang)(guang)的(de)傳(chuan)播速度是(shi)(shi)非(fei)常快的(de)，因此基于光(guang)(guang)(guang)速傳(chuan)播的(de)光(guang)(guang)(guang)電傳(chuan)感器的(de)響應時間肯定也是(shi)(shi)非(fei)常短的(de)。而且光(guang)(guang)(guang)電傳(chuan)感器的(de)電路都是(shi)(shi)由(you)電子零件構成(cheng)的(de)，所以是(shi)(shi)不包含任(ren)何(he)機械性的(de)工作(zuo)時間的(de)。

優點四：分辨率高。

光電傳感器能通過(guo)(guo)高(gao)(gao)級(ji)設計(ji)技(ji)術使(shi)投(tou)光光束集中在(zai)小(xiao)光點(dian)，或(huo)通過(guo)(guo)構(gou)成特殊的(de)(de)受光光學系統，來實現高(gao)(gao)分辨(bian)率(lv)。也可進行微小(xiao)物體的(de)(de)檢測(ce)和高(gao)(gao)精度的(de)(de)位置檢測(ce)。

優點五：可實現非接觸的檢測。

光(guang)電(dian)傳感器(qi)(qi)可以無須(xu)機械性地接觸檢(jian)測物體便能(neng)實(shi)現檢(jian)測，因(yin)此不會對檢(jian)測物體和傳感器(qi)(qi)造成損傷。而且，這對于保護(hu)光(guang)電(dian)傳感器(qi)(qi)本身也是非(fei)常有利(li)的，能(neng)夠有效延長其使用(yong)壽命(ming)。

優點六：可實現對顏色的判別。

光電傳(chuan)感器通過檢(jian)測物體(ti)形成(cheng)的光的反射(she)率和吸收率，根據被(bei)投光的光線波長和檢(jian)測物體(ti)的顏色組合而有(you)所差異。利用這種性質，可對(dui)檢(jian)測物體(ti)的顏色進行檢(jian)測。

優點七：便于調整。

光電(dian)傳(chuan)感器在投射(she)可(ke)視光的類型中，投光光束(shu)是眼睛可(ke)見的，便于(yu)對檢測物體的位置進(jin)行調整。
