這個(ge)問題已經成為(wei)選購地(di)(di)磅(bang)(bang)(bang)(bang)的關鍵(jian)因素之一(yi)。地(di)(di)磅(bang)(bang)(bang)(bang)按秤體(ti)結(jie)構可分(fen)為(wei)：工(gong)字鋼地(di)(di)磅(bang)(bang)(bang)(bang)、T型梁地(di)(di)磅(bang)(bang)(bang)(bang)、U型鋼地(di)(di)磅(bang)(bang)(bang)(bang)、槽鋼地(di)(di)磅(bang)(bang)(bang)(bang)、鋼筋混凝土地(di)(di)磅(bang)(bang)(bang)(bang)（俗名水泥(ni)秤。作為(wei)秤的的組成部分(fen)—秤臺，地(di)(di)磅(bang)(bang)(bang)(bang)生產廠家，選用的材料及性能將會直(zhi)接(jie)影響到地(di)(di)磅(bang)(bang)(bang)(bang)的壽命，阜陽地(di)(di)磅(bang)(bang)(bang)(bang)，什么樣(yang)的秤體(ti)才適合自己使用呢？稱重儀表，又名稱重顯(xian)示(shi)(shi)器，地(di)(di)磅(bang)(bang)(bang)(bang)的價格，稱重顯(xian)示(shi)(shi)控(kong)制器，用于(yu)測(ce)量傳(chuan)感器傳(chuan)輸的電信號，再(zai)通過軟件處理顯(xian)示(shi)(shi)重量讀(du)數，并可將數據進一(yi)步(bu)傳(chuan)遞至打印(yin)機、大(da)屏(ping)幕顯(xian)示(shi)(shi)器、電腦管理系統。

按(an)使用環(huan)境狀況可(ke)(ke)分(fen)為(wei)防(fang)爆地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)和非(fei)防(fang)爆地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)；按(an)地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)的自(zi)動化程度可(ke)(ke)分(fen)為(wei)非(fei)自(zi)動地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)和自(zi)動地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)。們先簡單了解一下電子衡的工作原理。地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)按(an)傳感器輸(shu)出(chu)信號(hao)分(fen)類可(ke)(ke)分(fen)為(wei)模(mo)擬式(shi)地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)和數字式(shi)地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)；關于不同結(jie)地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)的性能(neng)好壞，下面為(wei)你(ni)一一道來：工字鋼(gang)(gang)地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)：工字鋼(gang)(gang)是(shi)截面為(wei)工字形(xing)的長條鋼(gang)(gang)材，地(di)(di)(di)(di)磅(bang)(bang)(bang)(bang)價格廠家，抗(kang)壓、承受力強(qiang)，并(bing)且秤體不容(rong)易(yi)出(chu)現(xian)故障，是(shi)上(shang)選。

當負荷長時間(jian)加在(zai)一稱(cheng)重傳(chuan)(chuan)感器上時，其輸出常有較大(da)變(bian)化(hua)(hua)，數(shu)(shu)字式(shi)(shi)稱(cheng)重傳(chuan)(chuan)感器通(tong)過內部微處理器里(li)的(de)軟件，自(zi)動(dong)補償(chang)了蠕變(bian)。數(shu)(shu)字式(shi)(shi)地(di)磅能(neng)自(zi)動(dong)補償(chang)和調整因偏(pian)載和溫度變(bian)化(hua)(hua)產生的(de)影響。故障自(zi)動(dong)診(zhen)斷，出錯(cuo)信息代碼提示功(gong)能(neng)；模擬式(shi)(shi)傳(chuan)(chuan)感器的(de)輸出信號一般在(zai)數(shu)(shu)十毫伏，在(zai)電纜傳(chuan)(chuan)輸這些弱信號過程中，很容易受到干擾(rao)，從而造(zao)成系統工作不穩(wen)定或(huo)計量準(zhun)確(que)性降低。
