一(yi)般來說(shuo)(shuo)，傳(chuan)(chuan)感(gan)器(qi)的(de)量(liang)(liang)(liang)程越接近(jin)分配到(dao)每個傳(chuan)(chuan)感(gan)器(qi)的(de)載(zai)荷，其稱量(liang)(liang)(liang)的(de)準確度(du)就(jiu)越高(gao)。但在(zai)實習運用時，因為加在(zai)傳(chuan)(chuan)感(gan)器(qi)上的(de)載(zai)荷除被稱物體(ti)外，還存在(zai)秤體(ti)自(zi)重、皮重、偏載(zai)及振動沖擊等載(zai)荷，因此選用傳(chuan)(chuan)感(gan)器(qi)量(liang)(liang)(liang)程時，要考慮諸多(duo)方(fang)面的(de)要素，確保傳(chuan)(chuan)感(gan)器(qi)的(de)安全和(he)壽數。今天說(shuo)(shuo)下(xia)稱重傳(chuan)(chuan)感(gan)器(qi)的(de)數量(liang)(liang)(liang)和(he)量(liang)(liang)(liang)程原(yuan)理：

  1、稱重傳感器的數量和量程

  一(yi)般應使(shi)(shi)(shi)稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)在(zai)(zai)其(qi)30%～70%量(liang)程內工作。但對于一(yi)些在(zai)(zai)運用(yong)(yong)過程中(zhong)存在(zai)(zai)較大(da)沖擊力的衡(heng)器(qi)(qi)(qi)(qi)(qi)，如動(dong)態軌(gui)道(dao)衡(heng)、動(dong)態汽車(che)衡(heng)、鋼(gang)材秤(cheng)(cheng)等(deng)(deng)，在(zai)(zai)選(xuan)用(yong)(yong)稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)時，一(yi)般要拓展其(qi)量(liang)程，使(shi)(shi)(shi)稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)在(zai)(zai)其(qi)量(liang)程的20%～30%以內工作，使(shi)(shi)(shi)稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)的稱(cheng)(cheng)(cheng)量(liang)儲藏量(liang)程增大(da)，以確(que)保稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)的運用(yong)(yong)安(an)全和壽數。稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)型(xing)式(shi)的選(xuan)擇首要取決(jue)于稱(cheng)(cheng)(cheng)量(liang)的類型(xing)和設備(bei)(bei)空間，確(que)保設備(bei)(bei)適(shi)宜，稱(cheng)(cheng)(cheng)量(liang)安(an)全可靠；另(ling)一(yi)方面，要考慮稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)制造(zao)廠(chang)的建議。制造(zao)廠(chang)一(yi)般會(hui)根據稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)的受力情況(kuang)、功(gong)用(yong)(yong)政策、設備(bei)(bei)方法、結(jie)構型(xing)式(shi)、彈性(xing)體的資料等(deng)(deng)特征規矩稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)的適(shi)用(yong)(yong)計(ji)劃，比如鋁式(shi)懸(xuan)臂(bei)梁稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)于計(ji)價(jia)秤(cheng)(cheng)、平臺秤(cheng)(cheng)、案秤(cheng)(cheng)等(deng)(deng)，鋼(gang)式(shi)懸(xuan)臂(bei)梁稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)于料斗秤(cheng)(cheng)、電子皮(pi)帶秤(cheng)(cheng)、分選(xuan)秤(cheng)(cheng)等(deng)(deng)，鋼(gang)質橋式(shi)稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)于軌(gui)道(dao)衡(heng)、汽車(che)衡(heng)、天車(che)秤(cheng)(cheng)等(deng)(deng)，柱式(shi)稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)適(shi)用(yong)(yong)于汽車(che)衡(heng)、動(dong)態軌(gui)道(dao)衡(heng)、大(da)噸位(wei)料斗秤(cheng)(cheng)等(deng)(deng)。稱(cheng)(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感(gan)(gan)器(qi)(qi)(qi)(qi)(qi)

  2、稱重傳(chuan)感器(qi)的準確度等級選(xuan)擇(ze)

  稱重(zhong)(zhong)傳感器的(de)(de)(de)準確(que)度(du)等(deng)(deng)級包括(kuo)稱重(zhong)(zhong)傳感器的(de)(de)(de)非線(xian)性、蠕(ru)變、重(zhong)(zhong)復(fu)性、滯(zhi)后(hou)(hou)、靈敏度(du)等(deng)(deng)技術政策。在(zai)選用的(de)(de)(de)時(shi)分不應當盲目尋求(qiu)高等(deng)(deng)級的(de)(de)(de)稱重(zhong)(zhong)傳感器，應當考慮電子(zi)衡(heng)的(de)(de)(de)準確(que)度(du)等(deng)(deng)級和(he)(he)本錢。一般情況下，選用稱重(zhong)(zhong)傳感器的(de)(de)(de)總精度(du)為非線(xian)性、不重(zhong)(zhong)復(fu)性和(he)(he)滯(zhi)后(hou)(hou)三項(xiang)政策的(de)(de)(de)之(zhi)和(he)(he)的(de)(de)(de)均方根值略(lve)高于秤的(de)(de)(de)精度(du)。稱重(zhong)(zhong)傳感器

  3、各(ge)種類型稱重(zhong)傳感(gan)器的運用計劃

  選用的(de)(de)(de)稱重(zhong)傳(chuan)(chuan)感器(qi)須(xu)滿(man)足表(biao)(biao)面(mian)(mian)輸入靈敏度(du)的(de)(de)(de)央(yang)求，須(xu)可(ke)以與所選表(biao)(biao)面(mian)(mian)匹配，滿(man)足整臺(tai)電(dian)子(zi)秤準確度(du)的(de)(de)(de)央(yang)求。一臺(tai)電(dian)子(zi)秤首要(yao)是(shi)由機(ji)械組織、稱重(zhong)傳(chuan)(chuan)感器(qi)、表(biao)(biao)面(mian)(mian)三有些構成，在對稱重(zhong)傳(chuan)(chuan)感器(qi)準確度(du)選擇的(de)(de)(de)時分(fen)，應(ying)使稱重(zhong)傳(chuan)(chuan)感器(qi)的(de)(de)(de)準確度(du)略高(gao)于理論核算值，因為(wei)理論一般遭到(dao)(dao)客觀條件的(de)(de)(de)束縛，如機(ji)械結構的(de)(de)(de)強度(du)、表(biao)(biao)面(mian)(mian)的(de)(de)(de)功用、秤的(de)(de)(de)工(gong)作環境惡劣(lie)程度(du)等要(yao)素都直(zhi)接影響到(dao)(dao)秤的(de)(de)(de)準確度(du)。因此要(yao)從(cong)各方面(mian)(mian)行進央(yang)求，統籌經濟效益，確保(bao)抵(di)達意圖。

  4、運用環(huan)境(jing)

  一般情況下，高(gao)溫環境(jing)對(dui)稱(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器構成(cheng)涂(tu)覆資料融化、焊(han)點開化、彈性體內應力發生結構改動(dong)等疑問；粉塵、濕潤對(dui)稱(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器構成(cheng)短路的(de)(de)影響；在腐蝕(shi)性較高(gao)的(de)(de)環境(jing)下會構成(cheng)稱(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器彈性體受損(sun)或發生短路表象；電磁場(chang)對(dui)稱(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器輸出會發生攪擾(rao)。相應的(de)(de)環境(jing)要素下咱們有必(bi)要選(xuan)擇對(dui)應的(de)(de)稱(cheng)(cheng)重(zhong)傳(chuan)(chuan)(chuan)感器才(cai)調滿足必(bi)要的(de)(de)稱(cheng)(cheng)重(zhong)央求。

  通過(guo)對(dui)稱(cheng)重傳感器(qi)的(de)數(shu)量和量程原理的(de)了解，相(xiang)信(xin)大家對(dui)稱(cheng)重傳感器(qi)有了一定的(de)了解。
