一般(ban)來說(shuo)，傳(chuan)感(gan)器(qi)的量(liang)(liang)程越接近分配到(dao)每個傳(chuan)感(gan)器(qi)的載(zai)荷(he)，其(qi)稱量(liang)(liang)的準確度就越高(gao)。但在實習運用(yong)時，因為(wei)加在傳(chuan)感(gan)器(qi)上(shang)的載(zai)荷(he)除(chu)被稱物體外，還存在秤體自重、皮重、偏載(zai)及振動沖擊等載(zai)荷(he)，因此選用(yong)傳(chuan)感(gan)器(qi)量(liang)(liang)程時，要(yao)考慮諸(zhu)多方面的要(yao)素，確保傳(chuan)感(gan)器(qi)的安全(quan)和壽數(shu)。今(jin)天(tian)說(shuo)下(xia)稱重傳(chuan)感(gan)器(qi)的數(shu)量(liang)(liang)和量(liang)(liang)程原理：

  1、稱(cheng)重傳(chuan)感(gan)器的數量和量程

  一(yi)(yi)(yi)般應使(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)在其(qi)30%～70%量(liang)(liang)程(cheng)(cheng)內(nei)工(gong)作(zuo)(zuo)。但對于一(yi)(yi)(yi)些在運(yun)用(yong)(yong)過程(cheng)(cheng)中存(cun)在較大沖擊力的(de)(de)衡(heng)器(qi)(qi)(qi)(qi)(qi)，如動態軌(gui)道(dao)衡(heng)、動態汽車衡(heng)、鋼材秤等，在選(xuan)用(yong)(yong)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)時，一(yi)(yi)(yi)般要拓展(zhan)其(qi)量(liang)(liang)程(cheng)(cheng)，使(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)在其(qi)量(liang)(liang)程(cheng)(cheng)的(de)(de)20%～30%以內(nei)工(gong)作(zuo)(zuo)，使(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)的(de)(de)稱(cheng)(cheng)量(liang)(liang)儲藏量(liang)(liang)程(cheng)(cheng)增(zeng)大，以確保(bao)(bao)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)的(de)(de)運(yun)用(yong)(yong)安全和壽數。稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)型(xing)式(shi)(shi)的(de)(de)選(xuan)擇(ze)首要取(qu)決(jue)于稱(cheng)(cheng)量(liang)(liang)的(de)(de)類型(xing)和設備空間，確保(bao)(bao)設備適宜，稱(cheng)(cheng)量(liang)(liang)安全可(ke)靠；另一(yi)(yi)(yi)方(fang)面，要考(kao)慮稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)制(zhi)造(zao)廠的(de)(de)建議。制(zhi)造(zao)廠一(yi)(yi)(yi)般會根據稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)的(de)(de)受力情況、功用(yong)(yong)政(zheng)策、設備方(fang)法、結構型(xing)式(shi)(shi)、彈(dan)性體的(de)(de)資料等特征規矩稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)的(de)(de)適用(yong)(yong)計(ji)劃，比如鋁式(shi)(shi)懸(xuan)臂梁稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)適用(yong)(yong)于計(ji)價秤、平臺秤、案秤等，鋼式(shi)(shi)懸(xuan)臂梁稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)適用(yong)(yong)于料斗(dou)秤、電子(zi)皮帶秤、分選(xuan)秤等，鋼質橋式(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)適用(yong)(yong)于軌(gui)道(dao)衡(heng)、汽車衡(heng)、天車秤等，柱式(shi)(shi)稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)適用(yong)(yong)于汽車衡(heng)、動態軌(gui)道(dao)衡(heng)、大噸(dun)位料斗(dou)秤等。稱(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)

  2、稱重傳感器的準確度等級選擇

  稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)的準確(que)度(du)等級(ji)包括稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)的非(fei)線性、蠕變、重(zhong)復性、滯(zhi)后(hou)、靈敏度(du)等技(ji)術政策。在選用的時(shi)分不應當(dang)盲(mang)目尋求高(gao)等級(ji)的稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)，應當(dang)考(kao)慮電子衡的準確(que)度(du)等級(ji)和(he)本錢。一般情(qing)況(kuang)下，選用稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)的總精度(du)為非(fei)線性、不重(zhong)復性和(he)滯(zhi)后(hou)三項(xiang)政策的之(zhi)和(he)的均(jun)方根值略高(gao)于秤的精度(du)。稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)

  3、各種類型(xing)稱重傳感器的運用計劃

  選(xuan)用的(de)(de)(de)(de)稱重(zhong)傳(chuan)感器(qi)須滿(man)足(zu)表(biao)面(mian)輸入靈(ling)敏(min)度(du)(du)(du)的(de)(de)(de)(de)央求，須可以與所選(xuan)表(biao)面(mian)匹(pi)配，滿(man)足(zu)整臺電子秤(cheng)(cheng)準(zhun)(zhun)確(que)(que)度(du)(du)(du)的(de)(de)(de)(de)央求。一(yi)臺電子秤(cheng)(cheng)首要是由機(ji)械(xie)組織、稱重(zhong)傳(chuan)感器(qi)、表(biao)面(mian)三(san)有(you)些構成，在對稱重(zhong)傳(chuan)感器(qi)準(zhun)(zhun)確(que)(que)度(du)(du)(du)選(xuan)擇的(de)(de)(de)(de)時分，應使稱重(zhong)傳(chuan)感器(qi)的(de)(de)(de)(de)準(zhun)(zhun)確(que)(que)度(du)(du)(du)略高于理論核算值，因為理論一(yi)般遭到客觀條件的(de)(de)(de)(de)束(shu)縛，如機(ji)械(xie)結構的(de)(de)(de)(de)強度(du)(du)(du)、表(biao)面(mian)的(de)(de)(de)(de)功用、秤(cheng)(cheng)的(de)(de)(de)(de)工(gong)作(zuo)環境惡(e)劣(lie)程度(du)(du)(du)等要素都直接影響(xiang)到秤(cheng)(cheng)的(de)(de)(de)(de)準(zhun)(zhun)確(que)(que)度(du)(du)(du)。因此要從(cong)各方面(mian)行進(jin)央求，統籌經濟效益，確(que)(que)保抵達意圖。

  4、運(yun)用環境(jing)

  一般情(qing)況下，高溫環(huan)境對稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)構成(cheng)涂覆資料融(rong)化、焊點(dian)開化、彈(dan)性體內應(ying)力發生(sheng)結構改動等(deng)疑問；粉塵、濕潤對稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)構成(cheng)短路的(de)影響；在腐蝕性較高的(de)環(huan)境下會(hui)構成(cheng)稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)彈(dan)性體受損或發生(sheng)短路表(biao)象；電磁場對稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)輸出(chu)會(hui)發生(sheng)攪擾。相應(ying)的(de)環(huan)境要素下咱們有(you)必要選擇對應(ying)的(de)稱(cheng)重(zhong)傳(chuan)感(gan)器(qi)才(cai)調(diao)滿足必要的(de)稱(cheng)重(zhong)央求。

  通過對稱重(zhong)(zhong)傳感器的(de)數量和(he)量程原(yuan)理的(de)了解，相信(xin)大(da)家(jia)對稱重(zhong)(zhong)傳感器有了一(yi)定的(de)了解。
