電子(zi)地磅（汽車(che)衡）一(yi)般(ban)采(cai)用(yong)橋式(shi)QS傳(chuan)(chuan)感(gan)(gan)器(qi)。一(yi)般(ban)由(you)4-8只傳(chuan)(chuan)感(gan)(gan)器(qi)，到(dao)接線(xian)(xian)盒，然后(hou)由(you)一(yi)條主線(xian)(xian)接到(dao)儀表上。不同(tong)(tong)廠家的(de)(de)傳(chuan)(chuan)感(gan)(gan)器(qi)，要根據說明(ming)書(shu)來接，不同(tong)(tong)廠家做出的(de)(de)傳(chuan)(chuan)感(gan)(gan)器(qi)線(xian)(xian)色(se)不同(tong)(tong)，四(si)根分(fen)別是(shi)正負激勵和正負信號。一(yi)般(ban)傳(chuan)(chuan)感(gan)(gan)器(qi)線(xian)(xian)的(de)(de)顏色(se)分(fen)為紅黑，綠(lv)白。紅黑綠(lv)白：紅白綠(lv)蘭等分(fen)標(biao)表示V+、V-、S+、S- 對應依次接到(dao)接線(xian)(xian)盒上即(ji)可。要根據秤臺的(de)(de)結構，分(fen)布，依次接入接線(xian)(xian)盒的(de)(de)1,2,3,4,5,6,7，8 并標(biao)號。這(zhe)樣方(fang)便檢修。

稱重(zhong)傳(chuan)感器(qi)(qi)的(de)(de)出線(xian)(xian)(xian)方式有4線(xian)(xian)(xian)和(he)(he)6線(xian)(xian)(xian)兩種(zhong)，模塊或稱重(zhong)變送器(qi)(qi)的(de)(de)接(jie)線(xian)(xian)(xian)也有4線(xian)(xian)(xian)和(he)(he)6線(xian)(xian)(xian)兩種(zhong)，要(yao)接(jie)4線(xian)(xian)(xian)還是(shi)6線(xian)(xian)(xian)先要(yao)看(kan)你的(de)(de)硬件要(yao)求是(shi)怎(zen)樣的(de)(de)，原(yuan)則是(shi)：傳(chuan)感器(qi)(qi)能接(jie)6線(xian)(xian)(xian)的(de)(de)不接(jie)4線(xian)(xian)(xian)，必須(xu)接(jie)4線(xian)(xian)(xian)的(de)(de)就要(yao)進(jin)行(xing)短(duan)接(jie)。一般的(de)(de)稱重(zhong)傳(chuan)感器(qi)(qi)都是(shi)六線(xian)(xian)(xian)制的(de)(de)，當(dang)接(jie)成四線(xian)(xian)(xian)制時，電源線(xian)(xian)(xian)（EXC-，EXC+）與反(fan)饋(kui)線(xian)(xian)(xian)（SEN-，SEN+）就分別(bie)短(duan)接(jie)了。SEN+和(he)(he)SEN-是(shi)補償線(xian)(xian)(xian)路電阻用的(de)(de)。SEN+和(he)(he)EXC+是(shi)通路的(de)(de)，SEN-和(he)(he)EXC-是(shi)通路的(de)(de)。

EXC+和(he)(he)EXC-是(shi)給稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)供(gong)(gong)電(dian)(dian)(dian)的(de)(de)(de)，但是(shi)由于稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模(mo)塊(kuai)和(he)(he)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)之間(jian)的(de)(de)(de)線路損(sun)耗，實際上(shang)(shang)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)接(jie)(jie)收(shou)到的(de)(de)(de)電(dian)(dian)(dian)壓(ya)會小于供(gong)(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)。每個(ge)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)都有(you)一(yi)個(ge)mV/V的(de)(de)(de)特性(xing)，它輸出的(de)(de)(de)m號與(yu)(yu)接(jie)(jie)收(shou)到的(de)(de)(de)電(dian)(dian)(dian)壓(ya)密切相關(guan)，SENS+和(he)(he)SENS-實際上(shang)(shang)是(shi)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)內的(de)(de)(de)一(yi)個(ge)高阻抗回路，可(ke)以(yi)將稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模(mo)塊(kuai)實際接(jie)(jie)收(shou)到的(de)(de)(de)電(dian)(dian)(dian)壓(ya)反(fan)(fan)饋給稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模(mo)塊(kuai)。假設(she)EXC+和(he)(he)EXC-為(wei)10V,線路損(sun)耗，傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)2mV/V，實際上(shang)(shang)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)輸出大信號為(wei)（）*2=19mV，而不(bu)是(shi)20mV。此時稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)內部就會把19mV作為(wei)大量(liang)程，前提是(shi)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)必須通(tong)過反(fan)(fan)饋回路把實際電(dian)(dian)(dian)壓(ya)反(fan)(fan)饋給稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模(mo)塊(kuai)。在(zai)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)上(shang)(shang)將EXC+與(yu)(yu) SENS+短(duan)接(jie)(jie)，EXC-與(yu)(yu)SENS-短(duan)接(jie)(jie)，僅限于傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)與(yu)(yu)稱(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)模(mo)塊(kuai)距離較近，電(dian)(dian)(dian)壓(ya)損(sun)耗非常(chang)小的(de)(de)(de)場合，否則測量(liang)存在(zai)誤差。
