稱(cheng)重(zhong)傳感器,是地(di)(di)磅(bang)的(de)部件(jian),起(qi)著將重(zhong)量(liang)值轉換成對(dui)應的(de)可測電(dian)信號的(de)作用,傳感器的(de)優劣(lie)直接關系(xi)到(dao)(dao)整臺地(di)(di)磅(bang)的(de)品質。槽鋼(gang)(gang)秤體(ti)底部有兩道撐重(zhong)梁,底部有封板(ban)可起(qi)到(dao)(dao)張力作用。但槽鋼(gang)(gang)秤等于是用鋼(gang)(gang)板(ban)拼湊上去的(de),中間是空(kong)的(de),撐重(zhong)性能(neng)較差(cha)。地(di)(di)磅(bang)按(an)秤體(ti)結構可分(fen)為:工字鋼(gang)(gang)地(di)(di)磅(bang)、T型梁地(di)(di)磅(bang) 、L梁鋼(gang)(gang)地(di)(di)磅(bang)、U型鋼(gang)(gang)地(di)(di)磅(bang)、槽鋼(gang)(gang)地(di)(di)磅(bang)、鋼(gang)(gang)筋混凝土地(di)(di)磅(bang);按(an)傳感器類型可分(fen)為數字式地(di)(di)磅(bang)、模擬式地(di)(di)磅(bang)。
們先簡單了(le)解一(yi)下電子衡(heng)的工(gong)作原理。地(di)磅(bang)(bang)按傳(chuan)感器(qi)輸(shu)出信號分類可分為(wei)模擬式地(di)磅(bang)(bang)和數字(zi)式地(di)磅(bang)(bang);作為(wei)秤的的組成部分—秤臺,選用的材(cai)料(liao)及(ji)性能將會直接影響到(dao)地(di)磅(bang)(bang)的壽(shou)命,什么樣的秤體才(cai)適(shi)合自己使用呢(ni)?但是由于工(gong)字(zi)鋼地(di)磅(bang)(bang)所(suo)用材(cai)料(liao),所(suo)以價格也貴(gui)。采(cai)用RS485總(zong)線(xian)技術,實現信號的遠(yuan)距離傳(chuan)輸(shu),傳(chuan)輸(shu)距離不低于1000米;
槽鋼秤體(ti)底(di)部(bu)(bu)有(you)兩道撐重(zhong)梁,底(di)部(bu)(bu)有(you)封板可起(qi)到張(zhang)力作用(yong)(yong)。但槽鋼秤等(deng)于是(shi)用(yong)(yong)鋼板拼(pin)湊上去(qu)的(de)(de)(de),中(zhong)間是(shi)空的(de)(de)(de),撐重(zhong)性(xing)能較差。貨物進(jin)入稱重(zhong)臺(tai),在貨物重(zhong)力作用(yong)(yong)下,使(shi)稱重(zhong)傳(chuan)(chuan)感器(qi)(qi)(qi)彈(dan)性(xing)體(ti)產生(sheng)彈(dan)性(xing)形(xing)變,粘貼于彈(dan)性(xing)體(ti)上的(de)(de)(de)應(ying)變計(ji)橋(qiao)路(lu)阻抗失(shi)去(qu)平衡,輸出(chu)與重(zhong)量(liang)數值成比例的(de)(de)(de)電信(xin)號,經傳(chuan)(chuan)感器(qi)(qi)(qi)內部(bu)(bu)的(de)(de)(de)放(fang)大器(qi)(qi)(qi)、A/D轉換器(qi)(qi)(qi)、微處理器(qi)(qi)(qi)等(deng)電子元器(qi)(qi)(qi)件處理輸出(chu)數字信(xin)號,再經中(zhong)繼器(qi)(qi)(qi)進(jin)入稱重(zhong)顯示(shi)儀表直接(jie)顯示(shi)出(chu)重(zhong)量(liang)等(deng)數據。L型(xing)鋼秤體(ti)具有(you)U型(xing)鋼的(de)(de)(de)所有(you)優點,同時,其(qi)通(tong)過加(jia)長(chang)的(de)(de)(de)承(cheng)(cheng)重(zhong)梁和整體(ti)鋼板配(pei)合構成連(lian)接(jie)部(bu)(bu),使(shi)連(lian)接(jie)部(bu)(bu)表面一體(ti)化(hua),壓(ya)力被分攤,承(cheng)(cheng)重(zhong)梁保證了承(cheng)(cheng)壓(ya)能力,長(chang)期實用(yong)(yong)也(ye)不會出(chu)現彎折,適合在超大型(xing)地磅的(de)(de)(de)秤體(ti)結合部(bu)(bu)實用(yong)(yong)。
