如果顯示儀表與計算(suan)機(ji)、打(da)印機(ji)連接(jie),儀表可同(tong)時(shi)把重(zhong)量信(xin)號輸出(chu)給計算(suan)機(ji)等設備(bei),組成完整的稱重(zhong)管理(li)系統。關(guan)于不同(tong)結地(di)磅的性能好壞,下面為你一一道(dao)來:工字(zi)鋼(gang)地(di)磅:工字(zi)鋼(gang)是截面為工字(zi)形的長條(tiao)鋼(gang)材,抗壓、承受力強,并且(qie)秤(cheng)體不容易出(chu)現故障(zhang),是上選。鋼(gang)混地(di)磅又名水泥秤(cheng),與全(quan)(quan)地(di)磅區別在于秤(cheng)體結構的不同(tong),前者(zhe)是鋼(gang)筋混凝土結構,后(hou)者(zhe)是全(quan)(quan)鋼(gang)結構。
貨(huo)物進入稱(cheng)重(zhong)臺,在(zai)貨(huo)物重(zhong)力作(zuo)用下,使(shi)稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)彈性體(ti)產生彈性形變(bian),粘貼(tie)于(yu)彈性體(ti)上的(de)應變(bian)計橋(qiao)路阻(zu)抗失去(qu)平衡,輸(shu)(shu)出與重(zhong)量數值成比例的(de)電信(xin)號(hao),經傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)內(nei)部的(de)放大器(qi)(qi)(qi)、A/D轉換器(qi)(qi)(qi)、微(wei)處理(li)器(qi)(qi)(qi)等電子元器(qi)(qi)(qi)件處理(li)輸(shu)(shu)出數字(zi)(zi)信(xin)號(hao),再經中繼器(qi)(qi)(qi)進入稱(cheng)重(zhong)顯(xian)示儀表(biao)直接(jie)顯(xian)示出重(zhong)量等數據(ju)。們先簡單(dan)了解一下電子衡的(de)工(gong)作(zuo)原理(li)。地(di)(di)磅(bang)按傳(chuan)(chuan)感(gan)器(qi)(qi)(qi)輸(shu)(shu)出信(xin)號(hao)分(fen)類可分(fen)為模擬式地(di)(di)磅(bang)和數字(zi)(zi)式地(di)(di)磅(bang);但(dan)是由于(yu)工(gong)字(zi)(zi)鋼地(di)(di)磅(bang)所(suo)用材料,所(suo)以價格也(ye)貴(gui)。采用RS485總線技(ji)術,實現(xian)信(xin)號(hao)的(de)遠距(ju)離傳(chuan)(chuan)輸(shu)(shu),傳(chuan)(chuan)輸(shu)(shu)距(ju)離不低于(yu)1000米;
一(yi)致性,互(hu)換性好,多只傳感(gan)器并聯組(zu)秤后,可用軟件方(fang)法實現線性,修正(zheng)及性能補償,減少系(xi)統誤(wu)差(cha),簡化(hua)了秤體(ti)的(de)(de)現場安裝(zhuang)調試,標定,調整;這(zhe)個(ge)問題已經(jing)成為選購地(di)(di)(di)磅(bang)(bang)的(de)(de)關鍵因素之一(yi)。地(di)(di)(di)磅(bang)(bang)按秤體(ti)結構(gou)可分(fen)為:工字鋼(gang)地(di)(di)(di)磅(bang)(bang)、T型(xing)梁地(di)(di)(di)磅(bang)(bang)、U型(xing)鋼(gang)地(di)(di)(di)磅(bang)(bang)、槽鋼(gang)地(di)(di)(di)磅(bang)(bang)、鋼(gang)筋混凝土地(di)(di)(di)磅(bang)(bang)(俗(su)名水泥(ni)秤。隨著地(di)(di)(di)磅(bang)(bang)行業的(de)(de)發(fa)展,人(ren)們(men)對地(di)(di)(di)磅(bang)(bang)越來熟悉。機械式(shi)地(di)(di)(di)磅(bang)(bang)逐漸(jian)被(bei)精(jing)度高、穩定性好、 操(cao)作方(fang)便的(de)(de)模擬式(shi)地(di)(di)(di)磅(bang)(bang)和(he)數字式(shi)地(di)(di)(di)磅(bang)(bang)取(qu)代。
