槽(cao)鋼秤(cheng)體底部有兩道撐重梁(liang),底部有封板可起到張力(li)作用。但槽(cao)鋼秤(cheng)等(deng)于是用鋼板拼(pin)湊上去的,中(zhong)間是空(kong)的,撐重性能較差。稱重傳感器,是地(di)磅的部件(jian),起著(zhu)將重量值轉換(huan)成對應的可測(ce)電(dian)信號的作用,傳感器的優(you)劣(lie)直接關系到整臺(tai)(tai)(tai)地(di)磅的品(pin)質。按稱量方(fang)式(shi)分(fen)為靜態(tai)汽車衡和(he)動(dong)態(tai)地(di)磅;按安裝方(fang)式(shi)可分(fen)為地(di)上衡和(he)地(di)中(zhong)衡;按秤(cheng)臺(tai)(tai)(tai)結構分(fen)為鋼結構臺(tai)(tai)(tai)面和(he)混凝土臺(tai)(tai)(tai)面;
在二十世紀80年代之前(qian)常(chang)見的(de)地(di)(di)磅(bang)一般是(shi)利用(yong)杠桿(gan)原(yuan)理(li)純機(ji)(ji)械(xie)構(gou)造的(de)機(ji)(ji)械(xie)式(shi)地(di)(di)磅(bang),也稱(cheng)(cheng)(cheng)(cheng)作機(ji)(ji)械(xie)地(di)(di)磅(bang)。 二十世紀80年代中(zhong)期(qi),隨著(zhu)高(gao)精(jing)度稱(cheng)(cheng)(cheng)(cheng)重傳感(gan)器(qi)技術的(de)日趨成(cheng)熟,越來越多的(de)地(di)(di)磅(bang)品牌進入中(zhong)國市(shi)場;標準配置主(zhu)要由(you)承重傳力(li)機(ji)(ji)構(gou)(秤體)、高(gao)精(jing)度稱(cheng)(cheng)(cheng)(cheng)重傳感(gan)器(qi)、稱(cheng)(cheng)(cheng)(cheng)重顯(xian)示儀表三(san)大(da)主(zhu)件組成(cheng),由(you)此即可完成(cheng)地(di)(di)磅(bang)基本(ben)的(de)稱(cheng)(cheng)(cheng)(cheng)重功能(neng),也可根據不同用(yong)戶的(de)要求,選配打印機(ji)(ji)、大(da)屏幕顯(xian)示器(qi)、稱(cheng)(cheng)(cheng)(cheng)重管理(li)軟件以完成(cheng)更高(gao)層次的(de)數據管理(li)及傳輸的(de)需要。地(di)(di)磅(bang),也被稱(cheng)(cheng)(cheng)(cheng)為(wei)汽車衡,設置在地(di)(di)面上(shang)的(de)大(da)磅(bang)秤,通常(chang)用(yong)來稱(cheng)(cheng)(cheng)(cheng)卡車的(de)載貨噸數。是(shi)廠礦、商家等用(yong)于大(da)宗貨物計量的(de)主(zhu)要稱(cheng)(cheng)(cheng)(cheng)重設備(bei)。
槽鋼(gang)秤(cheng)(cheng)(cheng)體(ti)(ti)底部(bu)有兩道撐(cheng)重(zhong)(zhong)梁(liang),底部(bu)有封板可(ke)起到張力(li)作用(yong)。但槽鋼(gang)秤(cheng)(cheng)(cheng)等(deng)于是用(yong)鋼(gang)板拼湊上(shang)去的(de),中間是空的(de),撐(cheng)重(zhong)(zhong)性(xing)能較差。貨(huo)物(wu)進入稱(cheng)(cheng)重(zhong)(zhong)臺,在貨(huo)物(wu)重(zhong)(zhong)力(li)作用(yong)下(xia),使(shi)稱(cheng)(cheng)重(zhong)(zhong)傳感器(qi)(qi)(qi)彈(dan)性(xing)體(ti)(ti)產生彈(dan)性(xing)形變(bian)(bian),粘(zhan)貼于彈(dan)性(xing)體(ti)(ti)上(shang)的(de)應變(bian)(bian)計橋(qiao)路阻抗失(shi)去平衡,輸出與重(zhong)(zhong)量數(shu)值成比例的(de)電信號,經傳感器(qi)(qi)(qi)內部(bu)的(de)放大(da)器(qi)(qi)(qi)、A/D轉換器(qi)(qi)(qi)、微處(chu)理器(qi)(qi)(qi)等(deng)電子元器(qi)(qi)(qi)件處(chu)理輸出數(shu)字信號,再經中繼器(qi)(qi)(qi)進入稱(cheng)(cheng)重(zhong)(zhong)顯示儀表直接顯示出重(zhong)(zhong)量等(deng)數(shu)據(ju)。L型鋼(gang)秤(cheng)(cheng)(cheng)體(ti)(ti)具有U型鋼(gang)的(de)所有優點,同時,其通過(guo)加長的(de)承(cheng)重(zhong)(zhong)梁(liang)和整體(ti)(ti)鋼(gang)板配(pei)合構成連接部(bu),使(shi)連接部(bu)表面一體(ti)(ti)化,壓力(li)被(bei)分攤,承(cheng)重(zhong)(zhong)梁(liang)保證了(le)承(cheng)壓能力(li),長期實(shi)用(yong)也不會(hui)出現彎(wan)折(zhe),適(shi)合在超(chao)大(da)型地磅的(de)秤(cheng)(cheng)(cheng)體(ti)(ti)結合部(bu)實(shi)用(yong)。
