KEYENCE基(ji)恩士位移(yi)傳感器(qi)是(shi)做什(shen)么用的_位移(yi)傳感器(qi)怎么用

一、KEYENCE基(ji)恩(en)士位移傳感(gan)器是做(zuo)什么用的

KEYENCE基恩士位移傳(chuan)感(gan)器是(shi)一種(zhong)屬于(yu)金(jin)屬感(gan)應的線性器件，位移傳(chuan)感(gan)器的作用是(shi)把各種(zhong)被測物理量轉換為電量。

二、KEYENCE基恩(en)士(shi)位移傳感器的使用方法

一(yi)般采用(yong)給(gei)位(wei)移(yi)傳感器(qi)加上(shang)一(yi)個電(dian)(dian)壓(ya)，利用(yong)其優良的平(ping)滑性，來檢測輸出電(dian)(dian)壓(ya)（輸出電(dian)(dian)阻改變(bian)輸出電(dian)(dian)壓(ya)）分壓(ya)比。就可以直接不同(tong)類(lei)別的位(wei)移(yi)傳感器(qi)的使用(yong)方(fang)法也有不同(tong)。

KEYENCE基恩士位(wei)移傳感器使用(yong)方法是根據實際要求在油(you)(you)壓機的(de)主缸、液壓墊(dian)上分別安裝(zhuang)Kl下滑(hua)板式、KTC拉桿式直(zhi)線位(wei)移傳感器。在一個半自(zi)動工作過程(cheng)中，油(you)(you)壓機的(de)主缸、液壓墊(dian)分別帶動兩只(zhi)直(zhi)線位(wei)移傳感器移動，將(jiang)采集到(dao)的(de)兩點模擬量(liang)值(zhi)輸(shu)入到(dao)FX2N-8AD，FX2N-8AD將(jiang)此模擬輸(shu)入數值(zhi)（此時(shi)是電壓輸(shu)入），轉(zhuan)換成數字(zi)值(zhi)，并且(qie)把他們傳輸(shu)到(dao)PLC主單(dan)元。主缸、液壓墊(dian)選用(yong)直(zhi)線位(wei)移傳感器的(de)有效測量(liang)長度為500mm、400mm。

KEYENCE基(ji)恩士位移傳(chuan)感器在使(shi)用(yong)時應注(zhu)意哪(na)些事項(xiang)呢？首先電子(zi)尺是作為分壓器使(shi)用(yong)，以相對(dui)電壓來(lai)顯示所測(ce)量位置(zhi)(zhi)的實際(ji)位置(zhi)(zhi)。因此，就對(dui)這個(ge)裝置(zhi)(zhi)（電子(zi)尺）提出了(le)幾(ji)點要求：

不(bu)能(neng)接錯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子尺的(de)三條線(xian)(xian)(xian)(xian)(xian)(xian)(xian)，1#、3#線(xian)(xian)(xian)(xian)(xian)(xian)(xian)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)，2#是輸(shu)出線(xian)(xian)(xian)(xian)(xian)(xian)(xian)除(chu)(chu)1#、3#線(xian)(xian)(xian)(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)可(ke)(ke)以調換外，2#線(xian)(xian)(xian)(xian)(xian)(xian)(xian)只能(neng)是輸(shu)出線(xian)(xian)(xian)(xian)(xian)(xian)(xian)。上述(shu)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)一旦接錯，將出現(xian)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)性(xing)誤差(cha)大(da)，控(kong)制(zhi)精度(du)差(cha)，容易(yi)顯示(shi)跳動(dong)等現(xian)象。如(ru)(ru)果(guo)(guo)出現(xian)控(kong)制(zhi)非常困難(nan)，就(jiu)應該懷(huai)疑是接錯線(xian)(xian)(xian)(xian)(xian)(xian)(xian)。安(an)裝對中(zhong)性(xing)要(yao)好(hao)，角(jiao)(jiao)度(du)容許±12°誤差(cha)，平行(xing)度(du)偏差(cha)容許±0.5mm，是指某一誤差(cha)，如(ru)(ru)果(guo)(guo)角(jiao)(jiao)度(du)誤差(cha)和平行(xing)度(du)誤差(cha)都(dou)偏大(da)，就(jiu)會(hui)導致(zhi)顯示(shi)數字跳動(dong)。在這種情況(kuang)(kuang)下(xia)(xia)，一般(ban)可(ke)(ke)以用萬用表(biao)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)檔測出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)波(bo)動(dong)。一定(ding)要(yao)作角(jiao)(jiao)度(du)和平行(xing)度(du)的(de)調整。請特別(bie)注意(yi)：在現(xian)場(chang)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子尺的(de)鋁合金支架(jia)更換成不(bu)銹鋼支架(jia)后，同時(shi)應將拉桿牽引安(an)裝位升(sheng)高2Mm。否則(ze)，接地問題解(jie)決(jue)了(le)，又形成了(le)不(bu)對中(zhong)的(de)問題，必(bi)須同時(shi)解(jie)決(jue)。供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)要(yao)有足夠的(de)容量(liang)(liang)，如(ru)(ru)果(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)容量(liang)(liang)太(tai)小(xiao)，容易(yi)發生如(ru)(ru)下(xia)(xia)情況(kuang)(kuang)：合模運(yun)動(dong)會(hui)導致(zhi)射膠(jiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子尺顯示(shi)跳動(dong)，或熔膠(jiao)運(yun)動(dong)會(hui)導致(zhi)合模電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子尺的(de)顯示(shi)波(bo)動(dong)。特別(bie)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁閥驅動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子尺供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)在一起(qi)時(shi)容易(yi)出現(xian)上述(shu)情況(kuang)(kuang)，嚴重時(shi)可(ke)(ke)以用萬用表(biao)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)檔測量(liang)(liang)到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)波(bo)動(dong)。如(ru)(ru)果(guo)(guo)在排除(chu)(chu)了(le)靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)干(gan)擾、高頻干(gan)擾、對中(zhong)性(xing)不(bu)好(hao)的(de)情況(kuang)(kuang)下(xia)(xia)仍不(bu)能(neng)解(jie)決(jue)問題，也可(ke)(ke)以懷(huai)疑是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)的(de)功率偏小(xiao)。

KEYENCE基恩(en)士位(wei)移傳(chuan)感器(qi)如何標定？第(di)一步，先將高(gao)精度微位(wei)移傳(chuan)感器(qi)放置(zhi)在彈(dan)(dan)性(xing)體的(de)(de)一端的(de)(de)臺階孔內(nei)(nei)，用端蓋固定；然后(hou)轉動螺(luo)桿(gan)，拉近(jin)(jin)彈(dan)(dan)性(xing)體的(de)(de)上下(xia)兩個(ge)薄壁(bi)，彈(dan)(dan)性(xing)體內(nei)(nei)部出(chu)現彈(dan)(dan)性(xing)應力和變形(xing)，彈(dan)(dan)性(xing)體的(de)(de)兩個(ge)薄壁(bi)之間的(de)(de)垂(chui)直接(jie)近(jin)(jin)量(liang)通過(guo)螺(luo)桿(gan)下(xia)端的(de)(de)伸出(chu)量(liang)由位(wei)移傳(chuan)感器(qi)測(ce)得(de)；兩個(ge)端面(mian)即內(nei)(nei)端面(mian)和外端面(mian)的(de)(de)接(jie)近(jin)(jin)量(liang)通過(guo)高(gao)精度微位(wei)移傳(chuan)感器(qi)測(ce)得(de)；螺(luo)桿(gan)轉動到(dao)不同的(de)(de)位(wei)置(zhi)，擬合(he)出(chu)垂(chui)直接(jie)近(jin)(jin)量(liang)與水平接(jie)近(jin)(jin)量(liang)的(de)(de)比值C。
