KEYENCE基恩(en)士(shi)光(guang)電傳感器接線(xian)方法和圖解

　　KEYENCE基恩士光電(dian)傳感器(qi)(qi)的(de)(de)(de)接線(xian)方法(fa)取決(jue)于不同型(xing)號的(de)(de)(de)光電(dian)傳感器(qi)(qi)和它所(suo)連接的(de)(de)(de)設(she)備，一般來(lai)說有以下幾種常見(jian)接線(xian)方式：

　　1. KEYENCE基恩士光電傳感器兩線式(shi)接線法：適用于直接連接到配電盤或終端單元的(de)光電傳感器。傳輸目標信號的(de)線和地線需(xu)要連接到相應的(de)電源控制設備上。

　　2. KEYENCE基恩(en)士光(guang)電傳(chuan)感(gan)器三線(xian)式接線(xian)法(fa)：適用于(yu)采用PnP輸(shu)出信(xin)(xin)(xin)號(hao)的光(guang)電傳(chuan)感(gan)器。其中，一(yi)個傳(chuan)輸(shu)信(xin)(xin)(xin)號(hao)的線(xian)連(lian)(lian)接到智能(neng)終端單元，另一(yi)個信(xin)(xin)(xin)號(hao)線(xian)和地線(xian)連(lian)(lian)接到相應的控制設備上。

　　3. KEYENCE基恩(en)士光(guang)電(dian)傳(chuan)感(gan)器四線式接線法：適用于采用PnP輸出信(xin)號以(yi)及反向保護(hu)電(dian)路(lu)的(de)(de)(de)光(guang)電(dian)傳(chuan)感(gan)器。其中輸入電(dian)源線需要連(lian)接到智能終(zhong)端(duan)單元(yuan)或相應(ying)的(de)(de)(de)單元(yuan)，信(xin)號輸出線和反向保護(hu)電(dian)路(lu)接在相應(ying)的(de)(de)(de)控制器上，傳(chuan)輸地(di)線連(lian)接到大地(di)。

　　KEYENCE基恩(en)士光電傳感器下(xia)面介(jie)紹兩線式接線法的圖(tu)解：

　　兩線式接(jie)線法只有兩根(gen)(gen)導線，其中一根(gen)(gen)接(jie)通電流，另一根(gen)(gen)接(jie)回相應電池電極，適用于一些非智能(neng)型(xing)光電傳感器。

　　例如，此圖所示的光電對射遮(zhe)斷器通過兩(liang)根導線將信(xin)號(hao)輸出到(dao)PLC控制(zhi)器。

　　需要注意的(de)(de)是(shi)，接線(xian)連接和方法取(qu)決與(yu)具體的(de)(de)設備(bei)型號和控制(zhi)要求。操作前務必仔(zi)細閱讀設備(bei)說明書(shu)和產品(pin)文件(jian)，保(bao)險(xian)起見最(zui)好請專業人(ren)員進行安裝和接線(xian)調(diao)試。

　　KEYENCE基恩士光電(dian)(dian)(dian)(dian)(dian)傳感(gan)器(qi)是一種利(li)用電(dian)(dian)(dian)(dian)(dian)容(rong)作為敏(min)感(gan)元件，將被測(ce)壓(ya)(ya)力(li)(li)轉換(huan)成電(dian)(dian)(dian)(dian)(dian)容(rong)值(zhi)改(gai)變(bian)的(de)壓(ya)(ya)力(li)(li)傳感(gan)器(qi)。這(zhe)種壓(ya)(ya)力(li)(li)傳感(gan)器(qi)一般采(cai)用圓形金(jin)屬薄(bo)膜(mo)或(huo)鍍金(jin)屬薄(bo)膜(mo)作為電(dian)(dian)(dian)(dian)(dian)容(rong)器(qi)的(de)一個電(dian)(dian)(dian)(dian)(dian)極，當薄(bo)膜(mo)感(gan)受壓(ya)(ya)力(li)(li)而變(bian)形時，薄(bo)膜(mo)與(yu)固定(ding)(ding)電(dian)(dian)(dian)(dian)(dian)極之間形成的(de)電(dian)(dian)(dian)(dian)(dian)容(rong)量(liang)發生(sheng)變(bian)化，通過(guo)測(ce)量(liang)電(dian)(dian)(dian)(dian)(dian)路即可輸出與(yu)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)成一定(ding)(ding)關系(xi)的(de)電(dian)(dian)(dian)(dian)(dian)信號(hao)。電(dian)(dian)(dian)(dian)(dian)容(rong)式(shi)(shi)(shi)壓(ya)(ya)力(li)(li)傳感(gan)器(qi)屬于極距變(bian)化型電(dian)(dian)(dian)(dian)(dian)容(rong)式(shi)(shi)(shi)傳感(gan)器(qi)，可分(fen)為單電(dian)(dian)(dian)(dian)(dian)容(rong)式(shi)(shi)(shi)壓(ya)(ya)力(li)(li)傳感(gan)器(qi)和差動電(dian)(dian)(dian)(dian)(dian)容(rong)式(shi)(shi)(shi)壓(ya)(ya)力(li)(li)傳感(gan)器(qi)。

　　KEYENCE基(ji)恩士光電(dian)傳(chuan)(chuan)感(gan)器(qi)(qi)由圓(yuan)形薄(bo)(bo)膜(mo)(mo)(mo)與固定電(dian)極(ji)構成。薄(bo)(bo)膜(mo)(mo)(mo)在壓(ya)(ya)力(li)(li)的作用(yong)(yong)下變形，從而(er)改(gai)變電(dian)容(rong)器(qi)(qi)的容(rong)量(liang)(liang)(liang)，其靈(ling)敏度大致(zhi)與薄(bo)(bo)膜(mo)(mo)(mo)的面(mian)(mian)積(ji)和(he)壓(ya)(ya)力(li)(li)成正比而(er)與薄(bo)(bo)膜(mo)(mo)(mo)的張(zhang)(zhang)力(li)(li)和(he)薄(bo)(bo)膜(mo)(mo)(mo)到固定電(dian)極(ji)的距離成反(fan)比。另(ling)一種型(xing)式(shi)的固定電(dian)極(ji)取凹(ao)形球(qiu)面(mian)(mian)狀，膜(mo)(mo)(mo)片為(wei)周邊固定的張(zhang)(zhang)緊平(ping)面(mian)(mian)，膜(mo)(mo)(mo)片可用(yong)(yong)塑料鍍金屬(shu)層(ceng)的方法制成。這種型(xing)式(shi)適于測量(liang)(liang)(liang)低壓(ya)(ya)，并有(you)較(jiao)高過載(zai)能(neng)力(li)(li)。還可以(yi)采(cai)用(yong)(yong)帶活塞(sai)動極(ji)膜(mo)(mo)(mo)片制成測量(liang)(liang)(liang)高壓(ya)(ya)的單電(dian)容(rong)式(shi)壓(ya)(ya)力(li)(li)傳(chuan)(chuan)感(gan)器(qi)(qi)。這種型(xing)式(shi)可減小(xiao)膜(mo)(mo)(mo)片的直接(jie)受(shou)壓(ya)(ya)面(mian)(mian)積(ji)，以(yi)便采(cai)用(yong)(yong)較(jiao)薄(bo)(bo)的膜(mo)(mo)(mo)片提高靈(ling)敏度。它還與各種補償和(he)保護部(bu)以(yi)及放(fang)大電(dian)路(lu)整體封裝在一起，以(yi)便提高抗(kang)干擾能(neng)力(li)(li)。這種傳(chuan)(chuan)感(gan)器(qi)(qi)適于測量(liang)(liang)(liang)動態(tai)高壓(ya)(ya)和(he)對飛行(xing)器(qi)(qi)進行(xing)遙測。單電(dian)容(rong)式(shi)壓(ya)(ya)力(li)(li)傳(chuan)(chuan)感(gan)器(qi)(qi)還有(you)傳(chuan)(chuan)聲器(qi)(qi)式(shi)（即話筒式(shi)）和(he)聽診(zhen)器(qi)(qi)式(shi)等(deng)型(xing)式(shi)。

　　KEYENCE基恩士光電(dian)(dian)(dian)(dian)傳(chuan)感器(qi)的(de)(de)受(shou)壓(ya)(ya)膜片電(dian)(dian)(dian)(dian)極位于兩個固定電(dian)(dian)(dian)(dian)極之間，構成(cheng)兩個電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)。在壓(ya)(ya)力的(de)(de)作用下一(yi)個電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)的(de)(de)容(rong)(rong)量增大而(er)另一(yi)個則(ze)相應(ying)減小，測(ce)量結果(guo)由差(cha)動式電(dian)(dian)(dian)(dian)路(lu)輸出。它的(de)(de)固定電(dian)(dian)(dian)(dian)極是在凹(ao)曲(qu)的(de)(de)玻璃表面上鍍金(jin)屬(shu)層(ceng)而(er)制(zhi)成(cheng)。過載時膜片受(shou)到(dao)凹(ao)面的(de)(de)保(bao)護而(er)不(bu)致破裂。差(cha)動電(dian)(dian)(dian)(dian)容(rong)(rong)式壓(ya)(ya)力傳(chuan)感器(qi)比單電(dian)(dian)(dian)(dian)容(rong)(rong)式的(de)(de)靈敏(min)度(du)高、線(xian)性(xing)度(du)好，但(dan)加工較困難(nan)（特(te)別是難(nan)以保(bao)證對(dui)稱性(xing)），而(er)且(qie)不(bu)能實現對(dui)被測(ce)氣體或(huo)液體的(de)(de)隔離，因此不(bu)宜于工作在有腐蝕性(xing)或(huo)雜質的(de)(de)流體中。
