電子地(di)磅（汽(qi)車衡）一般采用橋(qiao)式QS傳感(gan)(gan)器。一般由4-8只(zhi)傳感(gan)(gan)器，匯總(zong)到接(jie)(jie)線(xian)(xian)盒，然后由一條主線(xian)(xian)接(jie)(jie)到儀表(biao)上。不(bu)同(tong)廠(chang)家(jia)的(de)傳感(gan)(gan)器，要根據說明書來接(jie)(jie)，不(bu)同(tong)廠(chang)家(jia)做出的(de)傳感(gan)(gan)器線(xian)(xian)色(se)不(bu)同(tong)，四根分別是(shi)正負激勵和正負信號(hao)。一般傳感(gan)(gan)器線(xian)(xian)的(de)顏(yan)色(se)分為紅(hong)黑，綠(lv)白。紅(hong)黑綠(lv)白：紅(hong)白綠(lv)蘭(lan)等分標表(biao)示V+、V-、S+、S- 對應(ying)依次(ci)接(jie)(jie)到接(jie)(jie)線(xian)(xian)盒上即(ji)可。要根據秤臺的(de)結構，分布，依次(ci)接(jie)(jie)入接(jie)(jie)線(xian)(xian)盒的(de)1,2,3,4,5,6,7，8 并(bing)標號(hao)。這樣方便(bian)檢修(xiu)。

分別短(duan)接(jie)了。SEN+和SEN-是補償線(xian)路電(dian)阻用(yong)的。SEN+和EXC+是通路的，SEN-和EXC-是通路的。

EXC+和(he)(he)EXC-是(shi)(shi)給稱重(zhong)傳(chuan)(chuan)感(gan)(gan)器供電(dian)(dian)(dian)的(de)，但是(shi)(shi)由于稱重(zhong)模塊(kuai)和(he)(he)傳(chuan)(chuan)感(gan)(gan)器之(zhi)間(jian)的(de)線路(lu)損耗，實(shi)(shi)際(ji)(ji)上傳(chuan)(chuan)感(gan)(gan)器接(jie)收(shou)到(dao)(dao)(dao)的(de)電(dian)(dian)(dian)壓會(hui)小(xiao)于供電(dian)(dian)(dian)電(dian)(dian)(dian)壓。每個稱重(zhong)傳(chuan)(chuan)感(gan)(gan)器都有(you)一個mV/V的(de)特性，它(ta)輸出的(de)mV信號(hao)與(yu)接(jie)收(shou)到(dao)(dao)(dao)的(de)電(dian)(dian)(dian)壓密切相(xiang)關，SENS+和(he)(he)SENS-實(shi)(shi)際(ji)(ji)上是(shi)(shi)稱重(zhong)傳(chuan)(chuan)感(gan)(gan)器內(nei)的(de)一個高阻(zu)抗(kang)回(hui)路(lu)，可以將稱重(zhong)模塊(kuai)實(shi)(shi)際(ji)(ji)接(jie)收(shou)到(dao)(dao)(dao)的(de)電(dian)(dian)(dian)壓反饋給稱重(zhong)模塊(kuai)。假(jia)設(she)EXC+和(he)(he)EXC-為(wei)10V,線路(lu)損耗，傳(chuan)(chuan)感(gan)(gan)器2mV/V，實(shi)(shi)際(ji)(ji)上傳(chuan)(chuan)感(gan)(gan)器輸出信號(hao)為(wei)（）*2=19mV，而(er)不(bu)是(shi)(shi)20mV。此時稱重(zhong)傳(chuan)(chuan)感(gan)(gan)器內(nei)部就(jiu)會(hui)把19mV作為(wei)量程，前提是(shi)(shi)傳(chuan)(chuan)感(gan)(gan)器必(bi)須通過反饋回(hui)路(lu)把實(shi)(shi)際(ji)(ji)電(dian)(dian)(dian)壓反饋給稱重(zhong)模塊(kuai)。在稱重(zhong)傳(chuan)(chuan)感(gan)(gan)器上將EXC+與(yu) SENS+短接(jie)，EXC-與(yu)SENS-短接(jie)，僅限于傳感器與稱重模塊距離較(jiao)近，電壓損耗非常(chang)小(xiao)的(de)場合(he)，否則(ze)測量存在(zai)誤差。
