這個問(wen)題已經成為選購地磅(bang)(bang)(bang)(bang)的(de)關鍵因素(su)之一(yi)。地磅(bang)(bang)(bang)(bang)按秤體結(jie)(jie)構可分為：工字鋼地磅(bang)(bang)(bang)(bang)、T型(xing)梁地磅(bang)(bang)(bang)(bang)、U型(xing)鋼地磅(bang)(bang)(bang)(bang)、槽鋼地磅(bang)(bang)(bang)(bang)、鋼筋混凝土地磅(bang)(bang)(bang)(bang)（俗名水泥秤。U型(xing)鋼秤體，則是根(gen)據橋(qiao)梁原(yuan)理，用U型(xing)鋼在底部進行支撐，抗(kang)側向力強，秤體抗(kang)繞(rao)。U型(xing)鋼的(de)底部是采(cai)用橋(qiao)梁結(jie)(jie)構設計的(de)。而數(shu)字式(shi)傳感(gan)器的(de)輸出(chu)信(xin)號均在3-4V左(zuo)右，其抗(kang)干(gan)擾(rao)能力遠大于(yu)模擬(ni)信(xin)號數(shu)百倍，解決(jue)傳輸信(xin)號弱及(ji)干(gan)擾(rao)問(wen)題；

槽(cao)鋼(gang)秤體(ti)底部(bu)(bu)有兩(liang)道撐(cheng)重(zhong)梁，地(di)磅(bang)廠(chang)家，底部(bu)(bu)有封板(ban)可起到張力(li)作(zuo)用(yong)(yong)。但槽(cao)鋼(gang)秤等于(yu)是用(yong)(yong)鋼(gang)板(ban)拼湊上(shang)去的(de)(de)，中(zhong)間是空(kong)的(de)(de)，撐(cheng)重(zhong)性(xing)(xing)能較(jiao)差。貨物(wu)進入稱重(zhong)臺(tai)，在(zai)貨物(wu)重(zhong)力(li)作(zuo)用(yong)(yong)下，使稱重(zhong)傳感器(qi)彈(dan)性(xing)(xing)體(ti)產生彈(dan)性(xing)(xing)形變(bian)，粘貼于(yu)彈(dan)性(xing)(xing)體(ti)上(shang)的(de)(de)應變(bian)計橋路阻抗失去平衡，輸(shu)(shu)出(chu)與(yu)重(zhong)量(liang)數值成比例的(de)(de)電(dian)信(xin)號，經(jing)傳感器(qi)內(nei)部(bu)(bu)的(de)(de)放(fang)大器(qi)、A/D轉換器(qi)、微處(chu)理(li)器(qi)等電(dian)子元器(qi)件(jian)處(chu)理(li)輸(shu)(shu)出(chu)數字信(xin)號，地(di)磅(bang) 報價，再經(jing)中(zhong)繼(ji)器(qi)進入稱重(zhong)顯示儀表(biao)直接顯示出(chu)重(zhong)量(liang)等數據(ju)。L型(xing)鋼(gang)秤體(ti)具有U型(xing)鋼(gang)的(de)(de)所(suo)有優(you)點，同時，其通過加長(chang)的(de)(de)承(cheng)重(zhong)梁和整體(ti)鋼(gang)板(ban)配(pei)合構成連接部(bu)(bu)，使連接部(bu)(bu)表(biao)面一體(ti)化，地(di)磅(bang)產廠(chang)家，壓力(li)被分(fen)攤，承(cheng)重(zhong)梁保證了承(cheng)壓能力(li)，長(chang)期實(shi)用(yong)(yong)也不會出(chu)現彎(wan)折，適合在(zai)超大型(xing)地(di)磅(bang)的(de)(de)秤體(ti)結合部(bu)(bu)實(shi)用(yong)(yong)。
