電子地(di)磅（汽車衡）一般(ban)采用(yong)橋(qiao)式(shi)QS傳(chuan)(chuan)感器(qi)。一般(ban)由(you)4-8只傳(chuan)(chuan)感器(qi)，匯總到接(jie)線盒(he)，然(ran)后由(you)一條主(zhu)線接(jie)到儀表上。不(bu)同廠家的傳(chuan)(chuan)感器(qi)，要根(gen)據說明(ming)書來接(jie)，不(bu)同廠家做出的傳(chuan)(chuan)感器(qi)線色不(bu)同，四根(gen)分別是正負激勵和正負信號(hao)。一般(ban)傳(chuan)(chuan)感器(qi)線的顏色分為紅(hong)(hong)黑，綠(lv)白。紅(hong)(hong)黑綠(lv)白：紅(hong)(hong)白綠(lv)蘭等分標表示(shi)V+、V-、S+、S- 對應依次接(jie)到接(jie)線盒(he)上即(ji)可(ke)。要根(gen)據秤臺的結構，分布(bu)，依次接(jie)入接(jie)線盒(he)的1,2,3,4,5,6,7，8 并標號(hao)。這樣(yang)方(fang)便檢修。

稱(cheng)(cheng)重(zhong)傳感(gan)器(qi)的(de)出(chu)線(xian)(xian)(xian)(xian)(xian)(xian)方式有4線(xian)(xian)(xian)(xian)(xian)(xian)和6線(xian)(xian)(xian)(xian)(xian)(xian)兩(liang)種(zhong)，模塊或稱(cheng)(cheng)重(zhong)變(bian)送(song)器(qi)的(de)接(jie)(jie)線(xian)(xian)(xian)(xian)(xian)(xian)也有4線(xian)(xian)(xian)(xian)(xian)(xian)和6線(xian)(xian)(xian)(xian)(xian)(xian)兩(liang)種(zhong)，要接(jie)(jie)4線(xian)(xian)(xian)(xian)(xian)(xian)還(huan)是(shi)(shi)6線(xian)(xian)(xian)(xian)(xian)(xian)首先要看你的(de)硬(ying)件(jian)要求是(shi)(shi)怎樣的(de)，原則是(shi)(shi)：傳感(gan)器(qi)能接(jie)(jie)6線(xian)(xian)(xian)(xian)(xian)(xian)的(de)不接(jie)(jie)4線(xian)(xian)(xian)(xian)(xian)(xian)，必須接(jie)(jie)4線(xian)(xian)(xian)(xian)(xian)(xian)的(de)就(jiu)要進行短接(jie)(jie)。一般的(de)稱(cheng)(cheng)重(zhong)傳感(gan)器(qi)都是(shi)(shi)六(liu)線(xian)(xian)(xian)(xian)(xian)(xian)制(zhi)的(de)，當接(jie)(jie)成(cheng)四(si)線(xian)(xian)(xian)(xian)(xian)(xian)制(zhi)時，電源線(xian)(xian)(xian)(xian)(xian)(xian)（EXC-，EXC+）與反饋(kui)線(xian)(xian)(xian)(xian)(xian)(xian)（SEN-，SEN+）就(jiu)分別短接(jie)(jie)了(le)。SEN+和SEN-是(shi)(shi)補償線(xian)(xian)(xian)(xian)(xian)(xian)路電阻用的(de)。SEN+和EXC+是(shi)(shi)通路的(de)，SEN-和EXC-是(shi)(shi)通路的(de)。

EXC+和(he)(he)EXC-是給(gei)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)供電(dian)(dian)的(de)，但是由(you)于(yu)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模塊(kuai)和(he)(he)傳感(gan)器(qi)(qi)之間的(de)線路(lu)損耗(hao)(hao)，實(shi)際(ji)(ji)上(shang)傳感(gan)器(qi)(qi)接收(shou)到的(de)電(dian)(dian)壓(ya)會小(xiao)于(yu)供電(dian)(dian)電(dian)(dian)壓(ya)。每個稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)都有一個mV/V的(de)特(te)性，它(ta)輸出的(de)m號與(yu)接收(shou)到的(de)電(dian)(dian)壓(ya)密切相關(guan)，SENS+和(he)(he)SENS-實(shi)際(ji)(ji)上(shang)是稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)內的(de)一個高阻抗回(hui)路(lu)，可以將稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模塊(kuai)實(shi)際(ji)(ji)接收(shou)到的(de)電(dian)(dian)壓(ya)反(fan)饋給(gei)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模塊(kuai)。假設EXC+和(he)(he)EXC-為10V,線路(lu)損耗(hao)(hao)，傳感(gan)器(qi)(qi)2mV/V，實(shi)際(ji)(ji)上(shang)傳感(gan)器(qi)(qi)輸出zui大信(xin)號為（）*2=19mV，而不是20mV。此時稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)內部就(jiu)會把(ba)19mV作為zui大量程，前提是傳感(gan)器(qi)(qi)必須通過反(fan)饋回(hui)路(lu)把(ba)實(shi)際(ji)(ji)電(dian)(dian)壓(ya)反(fan)饋給(gei)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模塊(kuai)。在稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳感(gan)器(qi)(qi)上(shang)將EXC+與(yu) SENS+短(duan)接，EXC-與(yu)SENS-短(duan)接，僅(jin)限于(yu)傳感(gan)器(qi)(qi)與(yu)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模塊(kuai)距離較近，電(dian)(dian)壓(ya)損耗(hao)(hao)非常小(xiao)的(de)場合，否則(ze)測(ce)量存在誤差。

4線(xian)(xian)(xian)式稱重傳感(gan)器怎(zen)么(me)跟接線(xian)(xian)(xian)盒連接線(xian)(xian)(xian)顏色是紅綠黑白：

一、4線(xian)式稱(cheng)重傳感器與接(jie)線(xian)盒接(jie)線(xian)

4線(xian)式(shi)稱重傳感器的(de)激勵（＋）接紅色線(xian)

4線式稱重傳感(gan)器(qi)的激勵（－）接(jie)黑色線

4線(xian)式稱重傳感器的信號（＋）接綠色(se)線(xian)

4線(xian)式稱重傳感器的(de)信號(hao)（－）接白色線(xian)

二、稱重傳(chuan)感(gan)器

（一(yi)）概(gai)念

稱(cheng)重(zhong)傳(chuan)感器由組合式S型梁結構(gou)及金屬(shu)箔式應變計構(gou)成(cheng)，具有(you)過載保(bao)護裝置(zhi)。測(ce)量精度(du)高、溫度(du)特性好、工作穩定(ding)等優。廣泛(fan)用(yong)于各種結構(gou)的動、靜態測(ce)量及各種電(dian)子稱(cheng)的一(yi)次儀表。

（二）工作原(yuan)理

1、被稱(cheng)重(zhong)(zhong)物(wu)或者載(zai)重(zhong)(zhong)汽(qi)車置于秤臺上(shang)，在重(zhong)(zhong)力效用下(xia)，秤臺將(jiang)(jiang)重(zhong)(zhong)力傳遞至彈性體支(zhi)承，使稱(cheng)重(zhong)(zhong)傳感器(qi)彈性體發生形變(bian)，貼附(fu)于彈性體應變(bian)梁上(shang)的(de)應變(bian)計橋路失去平衡，輸出與(yu)重(zhong)(zhong)量數據成(cheng)比例(li)的(de)差分電壓信號(hao)，經線性放大器(qi)將(jiang)(jiang)差分電壓信號(hao)放大。再經A/D轉(zhuan)換為數碼(ma)信號(hao)，由儀表(biao)的(de)微處(chu)理器(qi)（CPU）對(dui)重(zhong)(zhong)量信號(hao)進行計算、解(jie)碼(ma)等處(chu)理后直接顯重(zhong)(zhong)量數據。

2、是(shi)由一個或(huo)多個能(neng)在(zai)受(shou)力后產(chan)生形(xing)變(bian)(bian)的(de)(de)(de)(de)(de)彈(dan)(dan)性體，和能(neng)感應(ying)這個形(xing)變(bian)(bian)量的(de)(de)(de)(de)(de)電(dian)(dian)(dian)阻應(ying)變(bian)(bian)片(pian)組成的(de)(de)(de)(de)(de)電(dian)(dian)(dian)橋電(dian)(dian)(dian)路（如(ru)惠斯登電(dian)(dian)(dian)橋），以及能(neng)把電(dian)(dian)(dian)阻應(ying)變(bian)(bian)片(pian)固定粘貼在(zai)彈(dan)(dan)性體上(shang)并能(neng)傳導應(ying)變(bian)(bian)量的(de)(de)(de)(de)(de)粘合劑(ji)和保護電(dian)(dian)(dian)子電(dian)(dian)(dian)路的(de)(de)(de)(de)(de)密封膠等三大(da)部分組成測(ce)力傳感器。簡單說，就是(shi)應(ying)變(bian)(bian)片(pian)貼在(zai)彈(dan)(dan)性體上(shang)，當彈(dan)(dan)性體受(shou)力變(bian)(bian)形(xing)時，應(ying)變(bian)(bian)片(pian)也變(bian)(bian)形(xing)，同(tong)時應(ying)變(bian)(bian)片(pian)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)阻值發生變(bian)(bian)化，以此達到測(ce)量的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。
