們先簡單了解一下電子(zi)衡的工作(zuo)(zuo)原理。地(di)(di)(di)磅按傳感器(qi)輸出信號分類(lei)可分為模擬式(shi)(shi)地(di)(di)(di)磅和數字式(shi)(shi)地(di)(di)(di)磅；U型鋼(gang)(gang)秤(cheng)(cheng)體(ti)，則是根據橋梁原理，用(yong)U型鋼(gang)(gang)在底部進(jin)行支撐，抗側向力強，地(di)(di)(di)磅廠(chang)家，秤(cheng)(cheng)體(ti)抗繞(rao)。U型鋼(gang)(gang)的底部是采用(yong)橋梁結(jie)構(gou)設計(ji)的。在二十世(shi)紀(ji)80年(nian)代(dai)之前常見的地(di)(di)(di)磅一般是利用(yong)杠桿原理純(chun)機械構(gou)造的機械式(shi)(shi)地(di)(di)(di)磅，也稱作(zuo)(zuo)機械地(di)(di)(di)磅。 二十世(shi)紀(ji)80年(nian)代(dai)中期，隨(sui)著高精(jing)度稱重傳感器(qi)技術的日(ri)趨成(cheng)熟，越來(lai)越多的地(di)(di)(di)磅品牌(pai)進(jin)入(ru)中國(guo)市場；

數(shu)字式地(di)磅(bang)(bang)(bang)能自動(dong)(dong)補償和(he)調(diao)(diao)整(zheng)(zheng)因偏載和(he)溫(wen)度變化產生的(de)影響。故(gu)障自動(dong)(dong)診(zhen)斷，出錯(cuo)信息代碼提(ti)示功能；一致性(xing)，互換性(xing)好，多只(zhi)傳感(gan)器(qi)并聯組(zu)秤(cheng)后，可用軟件方法(fa)實現線性(xing)，淮南地(di)磅(bang)(bang)(bang)，修正(zheng)及(ji)性(xing)能補償，地(di)磅(bang)(bang)(bang) 價格(ge)，減少(shao)系統誤差，簡化了秤(cheng)體(ti)的(de)現場安裝(zhuang)調(diao)(diao)試，標定(ding)，調(diao)(diao)整(zheng)(zheng)；隨著(zhu)企(qi)業管(guan)理水(shui)平的(de)不斷提(ti)高，無人值守的(de)自動(dong)(dong)地(di)磅(bang)(bang)(bang)正(zheng)成為未來地(di)磅(bang)(bang)(bang)的(de)發展(zhan)方向(xiang)。將(jiang)物體(ti)的(de)重量(liang)傳遞給稱重傳感(gan)器(qi)的(de)機械(xie)平臺(tai)，常見有全鋼結構及(ji)鋼混結構二種型式。

貨物進(jin)入稱重(zhong)(zhong)(zhong)臺，在貨物重(zhong)(zhong)(zhong)力(li)作(zuo)用下，使(shi)稱重(zhong)(zhong)(zhong)傳感(gan)器(qi)彈性(xing)(xing)體(ti)(ti)產生彈性(xing)(xing)形(xing)變，粘(zhan)貼于(yu)彈性(xing)(xing)體(ti)(ti)上的(de)(de)(de)應(ying)變計橋路阻抗(kang)失去(qu)(qu)平(ping)衡，輸出(chu)與重(zhong)(zhong)(zhong)量數值成比例的(de)(de)(de)電(dian)信號，地磅的(de)(de)(de)價(jia)格(ge)，經(jing)傳感(gan)器(qi)內(nei)部(bu)(bu)的(de)(de)(de)放大器(qi)、A/D轉換器(qi)、微處理(li)器(qi)等電(dian)子元器(qi)件處理(li)輸出(chu)數字信號，再(zai)經(jing)中(zhong)繼器(qi)進(jin)入稱重(zhong)(zhong)(zhong)顯示儀表直接(jie)顯示出(chu)重(zhong)(zhong)(zhong)量等數據。槽鋼(gang)秤(cheng)體(ti)(ti)底部(bu)(bu)有兩道(dao)撐重(zhong)(zhong)(zhong)梁，底部(bu)(bu)有封板可起(qi)到(dao)張力(li)作(zuo)用。但槽鋼(gang)秤(cheng)等于(yu)是用鋼(gang)板拼湊(cou)上去(qu)(qu)的(de)(de)(de)，中(zhong)間是空的(de)(de)(de)，撐重(zhong)(zhong)(zhong)性(xing)(xing)能(neng)較差。作(zuo)為秤(cheng)的(de)(de)(de)的(de)(de)(de)組成部(bu)(bu)分—秤(cheng)臺，選用的(de)(de)(de)材料(liao)及性(xing)(xing)能(neng)將會直接(jie)影響到(dao)地磅的(de)(de)(de)壽命，什(shen)么樣(yang)的(de)(de)(de)秤(cheng)體(ti)(ti)才(cai)適合自己使(shi)用呢？
