壓式(shi)(shi)拉式(shi)(shi)稱重(zhong)傳感(gan)器(qi)安(an)(an)裝(zhuang)方法，這種(zhong)形式(shi)(shi)的稱重(zhong)傳感(gan)器(qi)有二種(zhong)不(bu)同(tong)的安(an)(an)裝(zhuang)形式(shi)(shi)。

一、為(wei)固定(ding)(ding)式底座傳感(gan)器的安(an)裝(zhuang)形式，安(an)裝(zhuang)時將(jiang)傳感(gan)器放置在(zai)三(san)顆固定(ding)(ding)檔柱內(nei)。因此要求使用在(zai)溫度變化范圍不大的場合，其優點是(shi)能提高秤(cheng)體的穩(wen)定(ding)(ding)性，而(er)且安(an)裝(zhuang)調試方便。在(zai)稱重(zhong)傳感(gan)器安(an)裝(zhuang)時還應注意：

1，為(wei)防(fang)止(zhi)大電(dian)流(liu)流(liu)經傳(chuan)(chuan)感器(qi)，應在(zai)傳(chuan)(chuan)感器(qi)之間加裝短路片，以防(fang)偶(ou)然(ran)的大電(dian)流(liu)流(liu)過而(er)將其燒壞。即使如此，在(zai)需要進行(xing)大從焊接(jie)時最好(hao)還是將壓式傳(chuan)(chuan)感器(qi)卸下，待幾作結束后再將稱(cheng)重傳(chuan)(chuan)感器(qi)安裝好(hao)。

2，滾珠等移動(dong)部件應保持滑動(dong)自如，不應有卡死、銹蝕等現象。

3，壓(ya)(ya)頭應(ying)由20mm厚(hou)的鉻(ge)鋼制成，壓(ya)(ya)頭的底面應(ying)加工成圓弧，其半徑應(ying)為傳感(gan)器(qi)圓頂(ding)半徑的3倍以上，并應(ying)進行熱處(chu)理(li)以增加壓(ya)(ya)頭的硬度(du)。固定板應(ying)用(yong)45號鋼制成，其厚(hou)度(du)不得(de)小于20mm，安裝時的水(shui)平度(du)不應(ying)超出±0.5°。

二、滾珠(zhu)式底座傳感器的安裝(zhuang)形式，安裝(zhuang)時將它(ta)放置(zhi)在(zai)帶有凹形缺口的底板上。其優點是(shi)：

當秤(cheng)體或其它設(she)備因溫度(du)影響而伸縮，使(shi)(shi)其偏(pian)離受(shou)力(li)中心(xin)線時，可(ke)作水(shui)平方向的(de)位(wei)移定位(wei)，其位(wei)移量(liang)在(zai)±5mm以內。因此可(ke)在(zai)任何情(qing)況下(xia)使(shi)(shi)稱(cheng)重傳感器接受(shou)垂直力(li)，保證稱(cheng)量(liang)準確度(du)。

零(ling)(ling)點溫(wen)漂(piao)是決定(ding)應變式傳(chuan)(chuan)感(gan)(gan)器(qi)質量的重(zhong)(zhong)要(yao)參數，同時(shi)也是進行(xing)(xing)溫(wen)度(du)補償(chang)的重(zhong)(zhong)要(yao)依(yi)據。因此在應變式稱重(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)生產(chan)過(guo)(guo)程中，必須在不同溫(wen)度(du)下測量傳(chuan)(chuan)感(gan)(gan)器(qi)零(ling)(ling)點輸(shu)出(chu)，通過(guo)(guo)對不同溫(wen)度(du)下的測量結果進行(xing)(xing)分析計算，并(bing)根據計算結果進行(xing)(xing)溫(wen)度(du)補償(chang)，同時(shi)剔除零(ling)(ling)點溫(wen)漂(piao)過(guo)(guo)大(da)的不合格的稱重(zhong)(zhong)傳(chuan)(chuan)感(gan)(gan)器(qi)。

該巡檢(jian)(jian)(jian)系統主要分(fen)為(wei)主控板(ban)(ban)和(he)檢(jian)(jian)(jian)測(ce)(ce)(ce)板(ban)(ban)兩個(ge)(ge)部(bu)分(fen)，其(qi)中檢(jian)(jian)(jian)測(ce)(ce)(ce)板(ban)(ban)對(dui)所(suo)連(lian)(lian)接(jie)的(de)稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)器進行(xing)零點輸出信(xin)號(hao)的(de)自動巡檢(jian)(jian)(jian)，并將測(ce)(ce)(ce)量(liang)結果(guo)發送至主控板(ban)(ban)。每塊檢(jian)(jian)(jian)測(ce)(ce)(ce)板(ban)(ban)一(yi)次最(zui)多可(ke)以連(lian)(lian)接(jie) 32個(ge)(ge)稱(cheng)重(zhong)傳(chuan)(chuan)感(gan)器，每個(ge)(ge)傳(chuan)(chuan)感(gan)器連(lian)(lian)接(jie)口(kou)都(dou)有固(gu)定的(de)ID編號(hao)，檢(jian)(jian)(jian)測(ce)(ce)(ce)板(ban)(ban)可(ke)以自動判斷(duan)每個(ge)(ge)連(lian)(lian)接(jie)口(kou)是(shi)否有傳(chuan)(chuan)感(gan)器的(de)連(lian)(lian)接(jie)。每塊檢(jian)(jian)(jian)測(ce)(ce)(ce)板(ban)(ban)都(dou)有可(ke)設(she)定的(de)獨立ID號(hao)，同時檢(jian)(jian)(jian)測(ce)(ce)(ce)板(ban)(ban)具有自診斷(duan)功能，可(ke)檢(jian)(jian)(jian)測(ce)(ce)(ce)出AD和(he)RAM等的(de)錯誤。

每塊主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)一次(ci)最(zui)多可(ke)以(yi)(yi)連(lian)接(jie)128塊檢(jian)測(ce)板(ban)(ban)(ban)(ban)，因此該系(xi)統(tong)最(zui)多可(ke)以(yi)(yi)同時(shi)巡(xun)檢(jian)4096個稱重傳感器(qi)。每次(ci)開機(ji)(ji)時(shi)，主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)會自動查(cha)詢所有(you)已(yi)連(lian)接(jie)的檢(jian)測(ce)板(ban)(ban)(ban)(ban)，當(dang)有(you)無法連(lian)接(jie)或有(you)檢(jian)測(ce)板(ban)(ban)(ban)(ban)報(bao)告錯誤時(shi)，主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)會在液晶(jing)屏上(shang)給(gei)出(chu)報(bao)警(jing)提(ti)示(shi)(shi)，操作(zuo)人(ren)員(yuan)可(ke)以(yi)(yi)根據(ju)需要選擇停機(ji)(ji)檢(jian)查(cha)，或者將出(chu)錯的檢(jian)測(ce)板(ban)(ban)(ban)(ban)設定為停用狀態，其后(hou)主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)將不再(zai)與該檢(jian)測(ce)板(ban)(ban)(ban)(ban)進(jin)行數(shu)據(ju)通(tong)訊(xun)。主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)主(zhu)要完(wan)(wan)成(cheng)檢(jian)測(ce)板(ban)(ban)(ban)(ban)數(shu)據(ju)采(cai)集(ji)、檢(jian)測(ce)數(shu)據(ju)分析計(ji)算、與PC機(ji)(ji)的數(shu)據(ju)通(tong)訊(xun)、打印控(kong)(kong)制和(he)人(ren)機(ji)(ji)交互等功(gong)能，并同樣具(ju)有(you)自診(zhen)斷(duan)功(gong)能，當(dang)出(chu)現故障時(shi)系(xi)統(tong)在液晶(jing)屏上(shang)給(gei)出(chu)報(bao)警(jing)提(ti)示(shi)(shi)，操作(zuo)人(ren)員(yuan)可(ke)根據(ju)提(ti)示(shi)(shi)信(xin)(xin)息進(jin)行相應的故障處理。操作(zuo)人(ren)員(yuan)對(dui)系(xi)統(tong)的所有(you)設定都可(ke)通(tong)過主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)上(shang)的按鍵完(wan)(wan)成(cheng)，主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)上(shang)還包括一塊 16×2的字符型(xing)液晶(jing)屏用于顯(xian)示(shi)(shi)各(ge)種信(xin)(xin)息。
