地(di)磅(bang),也(ye)被稱(cheng)為汽車衡,設置(zhi)在地(di)面上的大磅(bang)秤,通常用(yong)來稱(cheng)卡車的載(zai)貨噸數。是(shi)廠礦、商家等用(yong)于(yu)大宗貨物計(ji)量(liang)的主要稱(cheng)重設備(bei)。T型梁(liang)地(di)磅(bang):是(shi)行業新(xin)興的地(di)磅(bang)結(jie)構,該結(jie)構結(jie)合了槽(cao)鋼(gang)和工(gong)字鋼(gang)優點,秤體(ti)內加裝橫向(xiang)筋(jin)板(ban)(ban)、橫向(xiang)筋(jin)板(ban)(ban)高度根據噸位調節,底封加鋼(gang)板(ban)(ban),秤體(ti)面板(ban)(ban)與大梁(liang)組成一個結(jie)實的箱(xiang)型體(ti)。數字式地(di)磅(bang)能(neng)自(zi)(zi)動補償和調整(zheng)因(yin)偏載(zai)和溫度變化產生(sheng)的影(ying)響。故障自(zi)(zi)動診斷(duan),出錯信息(xi)代碼提示功能(neng);
貨物(wu)進入(ru)稱重臺(tai),在(zai)貨物(wu)重力作用(yong)(yong)下,使稱重傳(chuan)(chuan)感(gan)器(qi)(qi)彈(dan)性體(ti)產生(sheng)彈(dan)性形變,粘貼(tie)于彈(dan)性體(ti)上(shang)的(de)應變計橋(qiao)路阻抗失去平衡(heng),輸出與重量數(shu)值(zhi)成比例的(de)電(dian)信號(hao),經(jing)傳(chuan)(chuan)感(gan)器(qi)(qi)內部的(de)放大器(qi)(qi)、A/D轉(zhuan)換(huan)器(qi)(qi)、微處(chu)理器(qi)(qi)等電(dian)子(zi)元器(qi)(qi)件處(chu)理輸出數(shu)字(zi)信號(hao),再經(jing)中繼器(qi)(qi)進入(ru)稱重顯(xian)示儀(yi)表直接顯(xian)示出重量等數(shu)據。們(men)先簡單了解(jie)一下電(dian)子(zi)衡(heng)的(de)工作原理。地(di)磅(bang)按傳(chuan)(chuan)感(gan)器(qi)(qi)輸出信號(hao)分類可(ke)分為模擬式地(di)磅(bang)和數(shu)字(zi)式地(di)磅(bang);但是(shi)由(you)于工字(zi)鋼地(di)磅(bang)所用(yong)(yong)材料,所以價格(ge)也貴。采用(yong)(yong)RS485總線技術(shu),實現信號(hao)的(de)遠距離(li)傳(chuan)(chuan)輸,傳(chuan)(chuan)輸距離(li)不低于1000米(mi);
L型鋼秤(cheng)體具有(you)U型鋼的(de)所有(you)優點,同時,其通(tong)過(guo)加長(chang)的(de)承重梁和整(zheng)體鋼板配(pei)合構成連接部,使連接部表面一體化,壓力(li)被分攤,承重梁保證了承壓能力(li),長(chang)期實(shi)(shi)用也不會出(chu)現彎折,適合在超(chao)大(da)型地(di)磅的(de)秤(cheng)體結(jie)合部實(shi)(shi)用。按稱(cheng)量方式(shi)(shi)(shi)分為靜(jing)態(tai)汽(qi)車(che)衡和動態(tai)地(di)磅;按安裝方式(shi)(shi)(shi)可(ke)分為地(di)上衡和地(di)中衡;按秤(cheng)臺結(jie)構分為鋼結(jie)構臺面和混凝土(tu)臺面;當負荷長(chang)時間加在一稱(cheng)重傳感器(qi)上時,其輸出(chu)常有(you)較(jiao)大(da)變化,數(shu)字式(shi)(shi)(shi)稱(cheng)重傳感器(qi)通(tong)過(guo)內部微處(chu)理(li)器(qi)里(li)的(de)軟件(jian),自動補(bu)償(chang)了蠕(ru)變。
