一般來說，傳感(gan)器的(de)(de)量(liang)(liang)程越(yue)(yue)接近分(fen)配到(dao)每個傳感(gan)器的(de)(de)載(zai)(zai)荷(he)，其稱(cheng)(cheng)量(liang)(liang)的(de)(de)準(zhun)確(que)度就(jiu)越(yue)(yue)高。但在實習運用(yong)時，因(yin)為加(jia)在傳感(gan)器上的(de)(de)載(zai)(zai)荷(he)除被(bei)稱(cheng)(cheng)物體外，還存在秤體自(zi)重、皮重、偏載(zai)(zai)及(ji)振動沖擊等載(zai)(zai)荷(he)，因(yin)此選用(yong)傳感(gan)器量(liang)(liang)程時，要(yao)(yao)考(kao)慮諸多方面(mian)的(de)(de)要(yao)(yao)素，確(que)保傳感(gan)器的(de)(de)安全(quan)和(he)壽數(shu)。今天說下稱(cheng)(cheng)重傳感(gan)器的(de)(de)數(shu)量(liang)(liang)和(he)量(liang)(liang)程原(yuan)理：

  1、稱重傳感器的數量和(he)量程

  一般應使稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)在(zai)(zai)其30%～70%量(liang)程(cheng)內(nei)工(gong)作(zuo)。但對于(yu)(yu)(yu)一些在(zai)(zai)運(yun)用(yong)(yong)(yong)過程(cheng)中存(cun)在(zai)(zai)較大(da)沖擊(ji)力的(de)(de)衡(heng)(heng)器(qi)(qi)(qi)(qi)(qi)(qi)，如動(dong)態(tai)軌(gui)道(dao)衡(heng)(heng)、動(dong)態(tai)汽(qi)車(che)衡(heng)(heng)、鋼材秤(cheng)等(deng)，在(zai)(zai)選用(yong)(yong)(yong)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)時，一般要拓(tuo)展其量(liang)程(cheng)，使稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)在(zai)(zai)其量(liang)程(cheng)的(de)(de)20%～30%以(yi)內(nei)工(gong)作(zuo)，使稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)稱(cheng)(cheng)(cheng)量(liang)儲藏量(liang)程(cheng)增大(da)，以(yi)確保(bao)(bao)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)運(yun)用(yong)(yong)(yong)安(an)(an)全(quan)和(he)(he)壽(shou)數。稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)型式(shi)(shi)的(de)(de)選擇首要取決于(yu)(yu)(yu)稱(cheng)(cheng)(cheng)量(liang)的(de)(de)類型和(he)(he)設備空(kong)間(jian)，確保(bao)(bao)設備適(shi)(shi)宜，稱(cheng)(cheng)(cheng)量(liang)安(an)(an)全(quan)可靠；另一方面，要考慮稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)制(zhi)造(zao)廠(chang)(chang)的(de)(de)建議。制(zhi)造(zao)廠(chang)(chang)一般會根據(ju)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)受力情況、功用(yong)(yong)(yong)政策(ce)、設備方法、結(jie)構型式(shi)(shi)、彈(dan)性體的(de)(de)資料等(deng)特征規矩稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)適(shi)(shi)用(yong)(yong)(yong)計(ji)劃，比如鋁式(shi)(shi)懸臂梁(liang)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)適(shi)(shi)用(yong)(yong)(yong)于(yu)(yu)(yu)計(ji)價秤(cheng)、平臺(tai)秤(cheng)、案秤(cheng)等(deng)，鋼式(shi)(shi)懸臂梁(liang)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)適(shi)(shi)用(yong)(yong)(yong)于(yu)(yu)(yu)料斗秤(cheng)、電子皮(pi)帶(dai)秤(cheng)、分選秤(cheng)等(deng)，鋼質橋(qiao)式(shi)(shi)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)適(shi)(shi)用(yong)(yong)(yong)于(yu)(yu)(yu)軌(gui)道(dao)衡(heng)(heng)、汽(qi)車(che)衡(heng)(heng)、天車(che)秤(cheng)等(deng)，柱(zhu)式(shi)(shi)稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)適(shi)(shi)用(yong)(yong)(yong)于(yu)(yu)(yu)汽(qi)車(che)衡(heng)(heng)、動(dong)態(tai)軌(gui)道(dao)衡(heng)(heng)、大(da)噸位料斗秤(cheng)等(deng)。稱(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)(chuan)(chuan)(chuan)感(gan)(gan)(gan)器(qi)(qi)(qi)(qi)(qi)(qi)

  2、稱重(zhong)傳(chuan)感器的準確度等(deng)級選擇

  稱重(zhong)(zhong)傳感(gan)器(qi)的(de)準(zhun)(zhun)確度等級包(bao)括稱重(zhong)(zhong)傳感(gan)器(qi)的(de)非線性(xing)、蠕變、重(zhong)(zhong)復性(xing)、滯后、靈敏度等技術政策。在選用(yong)的(de)時分(fen)不應當盲目尋(xun)求高等級的(de)稱重(zhong)(zhong)傳感(gan)器(qi)，應當考慮電子衡(heng)的(de)準(zhun)(zhun)確度等級和本(ben)錢。一般情(qing)況下，選用(yong)稱重(zhong)(zhong)傳感(gan)器(qi)的(de)總精(jing)度為非線性(xing)、不重(zhong)(zhong)復性(xing)和滯后三項(xiang)政策的(de)之和的(de)均方根值略高于秤的(de)精(jing)度。稱重(zhong)(zhong)傳感(gan)器(qi)

  3、各種類型稱重傳感器的(de)運用計劃

  選(xuan)用的(de)(de)稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)須(xu)(xu)滿足(zu)表面(mian)輸入靈敏(min)度(du)(du)(du)的(de)(de)央求(qiu)，須(xu)(xu)可以與(yu)所選(xuan)表面(mian)匹配，滿足(zu)整臺電子秤(cheng)準確(que)度(du)(du)(du)的(de)(de)央求(qiu)。一臺電子秤(cheng)首要是由機械組織(zhi)、稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)、表面(mian)三有些構成(cheng)，在對(dui)稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)準確(que)度(du)(du)(du)選(xuan)擇的(de)(de)時(shi)分，應使(shi)稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)(qi)的(de)(de)準確(que)度(du)(du)(du)略(lve)高于(yu)理論核(he)算值，因為(wei)理論一般遭到(dao)客觀(guan)條件(jian)的(de)(de)束(shu)縛，如機械結(jie)構的(de)(de)強度(du)(du)(du)、表面(mian)的(de)(de)功用、秤(cheng)的(de)(de)工作環境惡劣程(cheng)度(du)(du)(du)等要素都直接影響到(dao)秤(cheng)的(de)(de)準確(que)度(du)(du)(du)。因此要從各方面(mian)行進央求(qiu)，統籌經(jing)濟效益，確(que)保抵達意圖。

  4、運(yun)用環境(jing)

  一般情況下(xia)，高(gao)溫環(huan)境對(dui)稱(cheng)重(zhong)傳感(gan)器(qi)(qi)構(gou)成(cheng)涂覆資(zi)料融化、焊點開化、彈性體內(nei)應(ying)力發生結構(gou)改動等(deng)疑問；粉塵、濕潤對(dui)稱(cheng)重(zhong)傳感(gan)器(qi)(qi)構(gou)成(cheng)短路的影響；在(zai)腐蝕性較高(gao)的環(huan)境下(xia)會構(gou)成(cheng)稱(cheng)重(zhong)傳感(gan)器(qi)(qi)彈性體受損或發生短路表象；電(dian)磁場對(dui)稱(cheng)重(zhong)傳感(gan)器(qi)(qi)輸(shu)出會發生攪擾(rao)。相(xiang)應(ying)的環(huan)境要素下(xia)咱(zan)們有必要選(xuan)擇對(dui)應(ying)的稱(cheng)重(zhong)傳感(gan)器(qi)(qi)才調滿足必要的稱(cheng)重(zhong)央求。

  通過對稱(cheng)重(zhong)傳感(gan)器的數(shu)量和量程(cheng)原理的了解(jie)(jie)，相信大家對稱(cheng)重(zhong)傳感(gan)器有了一定的了解(jie)(jie)。
