一般來(lai)說，傳(chuan)感(gan)器的(de)(de)量(liang)(liang)程越接近分配到每個傳(chuan)感(gan)器的(de)(de)載荷，其稱量(liang)(liang)的(de)(de)準確(que)度就越高。但在實(shi)習運用時(shi)，因為加在傳(chuan)感(gan)器上的(de)(de)載荷除被稱物體外，還存在秤體自重(zhong)、皮重(zhong)、偏載及振動沖擊等載荷，因此(ci)選用傳(chuan)感(gan)器量(liang)(liang)程時(shi)，要(yao)考慮諸多方(fang)面的(de)(de)要(yao)素(su)，確(que)保傳(chuan)感(gan)器的(de)(de)安全和壽數。今天說下稱重(zhong)傳(chuan)感(gan)器的(de)(de)數量(liang)(liang)和量(liang)(liang)程原理：

  1、稱重傳感器(qi)的數量和量程

  一(yi)般(ban)應(ying)使(shi)(shi)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)在(zai)其30%～70%量(liang)程內(nei)工作(zuo)。但對(dui)于(yu)一(yi)些(xie)在(zai)運(yun)用(yong)(yong)過(guo)程中(zhong)存在(zai)較(jiao)大沖(chong)擊力的(de)(de)衡(heng)(heng)器(qi)(qi)，如動(dong)態(tai)軌道(dao)衡(heng)(heng)、動(dong)態(tai)汽(qi)(qi)車衡(heng)(heng)、鋼材秤等(deng)，在(zai)選用(yong)(yong)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)時，一(yi)般(ban)要(yao)拓展其量(liang)程，使(shi)(shi)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)在(zai)其量(liang)程的(de)(de)20%～30%以內(nei)工作(zuo)，使(shi)(shi)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)的(de)(de)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)量(liang)儲藏量(liang)程增大，以確保稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)的(de)(de)運(yun)用(yong)(yong)安全和壽數(shu)。稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)型式(shi)的(de)(de)選擇首要(yao)取決于(yu)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)量(liang)的(de)(de)類(lei)型和設備(bei)空間，確保設備(bei)適(shi)宜，稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)量(liang)安全可靠；另一(yi)方面，要(yao)考慮(lv)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)制(zhi)(zhi)造(zao)廠(chang)的(de)(de)建議(yi)。制(zhi)(zhi)造(zao)廠(chang)一(yi)般(ban)會根據稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)的(de)(de)受(shou)力情(qing)況、功用(yong)(yong)政策、設備(bei)方法(fa)、結構型式(shi)、彈性體的(de)(de)資料(liao)等(deng)特征(zheng)規(gui)矩稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)的(de)(de)適(shi)用(yong)(yong)計劃(hua)，比如鋁式(shi)懸臂梁稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)適(shi)用(yong)(yong)于(yu)計價秤、平臺秤、案秤等(deng)，鋼式(shi)懸臂梁稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)適(shi)用(yong)(yong)于(yu)料(liao)斗秤、電子皮帶秤、分選秤等(deng)，鋼質(zhi)橋式(shi)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)適(shi)用(yong)(yong)于(yu)軌道(dao)衡(heng)(heng)、汽(qi)(qi)車衡(heng)(heng)、天車秤等(deng)，柱式(shi)稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)適(shi)用(yong)(yong)于(yu)汽(qi)(qi)車衡(heng)(heng)、動(dong)態(tai)軌道(dao)衡(heng)(heng)、大噸位料(liao)斗秤等(deng)。稱(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)重(zhong)(zhong)(zhong)傳(chuan)感(gan)(gan)(gan)器(qi)(qi)

  2、稱重(zhong)傳感器的準確度等級選(xuan)擇

  稱重(zhong)(zhong)(zhong)傳(chuan)感器的(de)(de)準(zhun)確度(du)等(deng)(deng)級(ji)包括稱重(zhong)(zhong)(zhong)傳(chuan)感器的(de)(de)非(fei)線性(xing)、蠕變、重(zhong)(zhong)(zhong)復性(xing)、滯后(hou)、靈敏(min)度(du)等(deng)(deng)技術政策。在選用(yong)的(de)(de)時分不(bu)應當盲目尋求高等(deng)(deng)級(ji)的(de)(de)稱重(zhong)(zhong)(zhong)傳(chuan)感器，應當考慮電子衡(heng)的(de)(de)準(zhun)確度(du)等(deng)(deng)級(ji)和(he)本(ben)錢(qian)。一(yi)般(ban)情況下，選用(yong)稱重(zhong)(zhong)(zhong)傳(chuan)感器的(de)(de)總精(jing)度(du)為非(fei)線性(xing)、不(bu)重(zhong)(zhong)(zhong)復性(xing)和(he)滯后(hou)三(san)項政策的(de)(de)之和(he)的(de)(de)均方根值(zhi)略高于秤的(de)(de)精(jing)度(du)。稱重(zhong)(zhong)(zhong)傳(chuan)感器

  3、各種類(lei)型稱(cheng)重(zhong)傳感器(qi)的(de)運用計劃

  選(xuan)(xuan)用的(de)稱重(zhong)傳感(gan)器須滿足表面(mian)輸入靈敏度(du)的(de)央(yang)求(qiu)，須可以(yi)與所(suo)選(xuan)(xuan)表面(mian)匹配，滿足整臺電子秤(cheng)(cheng)(cheng)準確(que)(que)(que)度(du)的(de)央(yang)求(qiu)。一(yi)臺電子秤(cheng)(cheng)(cheng)首要是由機械組織、稱重(zhong)傳感(gan)器、表面(mian)三(san)有(you)些構(gou)成，在對稱重(zhong)傳感(gan)器準確(que)(que)(que)度(du)選(xuan)(xuan)擇的(de)時分，應(ying)使稱重(zhong)傳感(gan)器的(de)準確(que)(que)(que)度(du)略高于理論核算值，因(yin)為理論一(yi)般遭到(dao)(dao)客觀條件的(de)束(shu)縛，如機械結構(gou)的(de)強度(du)、表面(mian)的(de)功用、秤(cheng)(cheng)(cheng)的(de)工(gong)作(zuo)環境惡劣(lie)程度(du)等要素都直接影響到(dao)(dao)秤(cheng)(cheng)(cheng)的(de)準確(que)(que)(que)度(du)。因(yin)此要從各方(fang)面(mian)行進央(yang)求(qiu)，統籌經濟效益，確(que)(que)(que)保抵(di)達意圖。

  4、運用環(huan)境(jing)

  一般情況下(xia)，高溫環境(jing)(jing)對(dui)稱(cheng)重(zhong)傳(chuan)感器(qi)構(gou)(gou)成涂覆資料融化、焊點(dian)開化、彈性(xing)體內應(ying)力發(fa)生結構(gou)(gou)改動等疑問；粉塵、濕潤對(dui)稱(cheng)重(zhong)傳(chuan)感器(qi)構(gou)(gou)成短路的影響；在腐蝕性(xing)較(jiao)高的環境(jing)(jing)下(xia)會構(gou)(gou)成稱(cheng)重(zhong)傳(chuan)感器(qi)彈性(xing)體受損或發(fa)生短路表象；電磁場對(dui)稱(cheng)重(zhong)傳(chuan)感器(qi)輸(shu)出會發(fa)生攪擾。相應(ying)的環境(jing)(jing)要素下(xia)咱(zan)們有必要選擇對(dui)應(ying)的稱(cheng)重(zhong)傳(chuan)感器(qi)才調滿(man)足(zu)必要的稱(cheng)重(zhong)央求。

  通(tong)過對稱重(zhong)傳感(gan)器的(de)數量和量程(cheng)原理的(de)了(le)(le)解，相(xiang)信大(da)家(jia)對稱重(zhong)傳感(gan)器有了(le)(le)一定的(de)了(le)(le)解。
