電(dian)(dian)子地(di)(di)磅汽(qi)車(che)(che)(che)(che)(che)衡(heng)(heng)(heng)是(shi)(shi)(shi)一(yi)種(zhong)用(yong)于(yu)稱(cheng)量大型貨物(wu)(wu)的(de)(de)(de)稱(cheng)重裝置。卡車(che)(che)(che)(che)(che)衡(heng)(heng)(heng)又稱(cheng)地(di)(di)面衡(heng)(heng)(heng)。經常使用(yong)電(dian)(dian)子地(di)(di)磅汽(qi)車(che)(che)(che)(che)(che)衡(heng)(heng)(heng)的(de)(de)(de)人都知道，在(zai)使用(yong)汽(qi)車(che)(che)(che)(che)(che)衡(heng)(heng)(heng)之(zhi)前必須(xu)進(jin)行校準，否則(ze)會影(ying)響稱(cheng)量的(de)(de)(de)準確(que)性。如(ru)(ru)果(guo)出現地(di)(di)磅跳數，首先要感覺是(shi)(shi)(shi)受潮了，打開(kai)接(jie)線(xian)盒(he)(he)看(kan)(kan)看(kan)(kan)有沒有水(shui)汽(qi)，如(ru)(ru)果(guo)有水(shui)汽(qi)，可以用(yong)電(dian)(dian)吹風吹干(gan)(gan)(gan)，如(ru)(ru)果(guo)烘干(gan)(gan)(gan)后仍然有水(shui)汽(qi)，再更換接(jie)線(xian)盒(he)(he)。 當電(dian)(dian)子汽(qi)車(che)(che)(che)(che)(che)衡(heng)(heng)(heng)充滿水(shui)時(shi)，稱(cheng)重儀(yi)的(de)(de)(de)顯(xian)示會不穩定(ding)和不準確(que)。我們得檢查接(jie)線(xian)盒(he)(he)。比較好的(de)(de)(de)解(jie)決辦(ban)法是(shi)(shi)(shi)拆下接(jie)線(xian)盒(he)(he)，把接(jie)線(xian)盒(he)(he)里的(de)(de)(de)水(shui)吹干(gan)(gan)(gan)，看(kan)(kan)看(kan)(kan)能(neng)不能(neng)適當稱(cheng)重。如(ru)(ru)果(guo)接(jie)線(xian)盒(he)(he)不工作，則(ze)需要更換接(jie)線(xian)盒(he)(he)。自動化電(dian)(dian)子汽(qi)車(che)(che)(che)(che)(che)衡(heng)(heng)(heng)稱(cheng)重管(guan)(guan)理系(xi)統主要針對企(qi)業在(zai)物(wu)(wu)料(liao)采購、產品銷(xiao)售和廠房物(wu)(wu)料(liao)轉移、物(wu)(wu)料(liao)分配過(guo)程中的(de)(de)(de)計量管(guan)(guan)理。該系(xi)統支(zhi)持市場上的(de)(de)(de)各種(zhong)外觀(guan)。在(zai)安裝電(dian)(dian)子汽(qi)車(che)(che)(che)(che)(che)衡(heng)(heng)(heng)時(shi)，需要根據設(she)計圖紙的(de)(de)(de)尺寸確(que)定(ding)電(dian)(dian)子汽(qi)車(che)(che)(che)(che)(che)衡(heng)(heng)(heng)的(de)(de)(de)基(ji)礎(chu)是(shi)(shi)(shi)否搭建好。更重要的(de)(de)(de)是(shi)(shi)(shi)，它是(shi)(shi)(shi)長(chang)度(du)、寬(kuan)度(du)和高度(du)、對角(jiao)線(xian)長(chang)度(du)等(deng)。

固定(ding)式(shi)軸重(zhong)秤，原理跟固定(ding)式(shi)電(dian)子汽(qi)車(che)(che)衡(heng)基(ji)本(ben)相同。但固定(ding)式(shi)軸重(zhong)秤每次(ci)稱(cheng)量的(de)(de)(de)是(shi)(shi)汽(qi)車(che)(che)各(ge)軸重(zhong)量，通過(guo)累加獲得整(zheng)車(che)(che)重(zhong)量。可(ke)以采(cai)(cai)用(yong)動態(tai)和靜態(tai)兩種稱(cheng)量方(fang)式(shi)。優點：可(ke)以滿(man)足各(ge)類(lei)汽(qi)車(che)(che)軸重(zhong)的(de)(de)(de)需求，結構輕小(xiao)，便(bian)(bian)于(yu)運輸(shu)、安裝(zhuang)調試。缺點：動態(tai)受車(che)(che)速、車(che)(che)型、路(lu)面狀況等(deng)情況的(de)(de)(de)影響，精度較低；靜態(tai)稱(cheng)量過(guo)程繁瑣，時間太長。動態(tai)汽(qi)車(che)(che)衡(heng)因其功能強大、測量準確(que)方(fang)便(bian)(bian)等(deng)特點，被廣泛應(ying)用(yong)于(yu)高速公路(lu)出口和普通公路(lu)。 在普通道路(lu)上使用(yong)動態(tai)汽(qi)車(che)(che)衡(heng)的(de)(de)(de)目(mu)的(de)(de)(de)是(shi)(shi)對任何(he)正在行駛(shi)的(de)(de)(de)車(che)(che)輛進行稱(cheng)重(zhong)，以確(que)定(ding)其是(shi)(shi)否超載，方(fang)便(bian)(bian)對超載的(de)(de)(de)管理和控制。電(dian)子地(di)磅設(she)備(bei)一般(ban)都(dou)是(shi)(shi)暴露(lu)在外面的(de)(de)(de)地(di)方(fang)，一般(ban)尺度負荷的(de)(de)(de)采(cai)(cai)集和操縱數據信息(xi)都(dou)要非常精細和詳細，地(di)應(ying)力分量(傳(chuan)感(gan)器)、放(fang)大和顯示(shi)系統都(dou)很容易受到雷擊(ji)危害，如防雷措施不完善(shan)，當射線沖擊(ji)或磁感(gan)應(ying)雷擊(ji)對傳(chuan)感(gan)器機械(xie)設(she)備(bei)的(de)(de)(de)破壞時，其附帶損(sun)害是(shi)(shi)非常大的(de)(de)(de)。
