稱重傳感器的用途
稱(cheng)(cheng)重傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)實(shi)際上是一種將質量(liang)信(xin)號轉換成(cheng)可測(ce)量(liang)的電(dian)(dian)信(xin)號輸出(chu)裝(zhuang)置(zhi)。用傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)首先要(yao)(yao)考慮傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)所處的實(shi)際工(gong)作環境，這點(dian)對于正(zheng)(zheng)確選(xuan)用傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)至關重要(yao)(yao)，它(ta)關系到傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)能否正(zheng)(zheng)常工(gong)作以及它(ta)的安(an)全和使用壽命，乃至整個衡器(qi)(qi)(qi)(qi)的可靠性(xing)和安(an)全性(xing)。一般(ban)情況(kuang)下(xia)，高溫環境對傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)造成(cheng)涂覆材料融化、焊點(dian)開化、彈性(xing)體內應(ying)力發生(sheng)(sheng)結(jie)構變(bian)(bian)(bian)化等問題；粉塵、潮(chao)濕對傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)造成(cheng)短路的影響；在腐蝕性(xing)較(jiao)高的環境下(xia)會造成(cheng)傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)彈性(xing)體受損(sun)或產(chan)生(sheng)(sheng)短路現(xian)象(xiang)；電(dian)(dian)磁場對傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)輸出(chu)會產(chan)生(sheng)(sheng)干擾(rao)。相應(ying)的環境因素下(xia)我們(men)必須選(xuan)擇對應(ying)的稱(cheng)(cheng)重傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)才(cai)能滿足必要(yao)(yao)的稱(cheng)(cheng)重要(yao)(yao)求。稱(cheng)(cheng)重傳(chuan)(chuan)(chuan)感器(qi)(qi)(qi)(qi)按轉換方法分為(wei)光電(dian)(dian)式(shi)、液(ye)壓式(shi)、電(dian)(dian)磁力式(shi)、電(dian)(dian)容式(shi)、磁極變(bian)(bian)(bian)形式(shi)、振動(dong)式(shi)、陀螺儀式(shi)、電(dian)(dian)阻應(ying)變(bian)(bian)(bian)式(shi)等8類，以電(dian)(dian)阻應(ying)變(bian)(bian)(bian)式(shi)使用*。
