壓式(shi)拉式(shi)稱重傳感(gan)器(qi)安裝方法，這(zhe)種(zhong)(zhong)形式(shi)的稱重傳感(gan)器(qi)有(you)二種(zhong)(zhong)不(bu)同(tong)的安裝形式(shi)。

一、為固定式底座傳感(gan)器(qi)的安(an)裝(zhuang)(zhuang)(zhuang)形式，安(an)裝(zhuang)(zhuang)(zhuang)時(shi)將傳感(gan)器(qi)放置在(zai)三顆固定檔柱(zhu)內。因此(ci)要求使用(yong)在(zai)溫度變化(hua)范圍不(bu)大的場合，其優點(dian)是能提高秤體的穩定性，而且安(an)裝(zhuang)(zhuang)(zhuang)調試(shi)方(fang)便。在(zai)稱重傳感(gan)器(qi)安(an)裝(zhuang)(zhuang)(zhuang)時(shi)還應注意：

1，為(wei)防止大電流(liu)流(liu)經(jing)傳感(gan)器，應在傳感(gan)器之間加(jia)裝短路片，以防偶然的大電流(liu)流(liu)過(guo)而將其燒壞。即使如此，在需要進行大從焊接時最好還是將壓(ya)式傳感(gan)器卸下，待幾(ji)作結(jie)束后再將稱(cheng)重傳感(gan)器安裝好。

2，滾珠等移動部件(jian)應保持滑動自如，不應有卡(ka)死、銹蝕等現(xian)象。

3，壓(ya)頭應由20mm厚的鉻(ge)鋼(gang)制成，壓(ya)頭的底(di)面應加(jia)工成圓弧，其半徑(jing)應為(wei)傳感器圓頂半徑(jing)的3倍以(yi)上，并應進行熱處理以(yi)增加(jia)壓(ya)頭的硬度(du)。固定板應用45號鋼(gang)制成，其厚度(du)不得小于20mm，安裝時的水平(ping)度(du)不應超(chao)出(chu)±0.5°。

二、滾珠式(shi)底座傳感器的(de)安(an)裝(zhuang)形(xing)式(shi)，安(an)裝(zhuang)時(shi)將它放置在帶(dai)有(you)凹形(xing)缺口(kou)的(de)底板上。其(qi)優點是：

當秤體或其它設備(bei)因溫度(du)影響而(er)伸(shen)縮(suo)，使其偏離受力中心(xin)線時，可作水(shui)平方向的位(wei)移(yi)定位(wei)，其位(wei)移(yi)量在±5mm以內。因此可在任(ren)何情況下使稱(cheng)重傳(chuan)感器接受垂直力，保證稱(cheng)量準(zhun)確度(du)。

零(ling)(ling)(ling)點溫(wen)漂是決定應變(bian)式(shi)(shi)傳(chuan)感器(qi)質量的(de)(de)(de)重要(yao)參數，同時(shi)也(ye)是進(jin)(jin)(jin)行溫(wen)度補(bu)償的(de)(de)(de)重要(yao)依(yi)據。因此在應變(bian)式(shi)(shi)稱重傳(chuan)感器(qi)生產過(guo)程(cheng)中，必須在不(bu)同溫(wen)度下測量傳(chuan)感器(qi)零(ling)(ling)(ling)點輸(shu)出，通過(guo)對不(bu)同溫(wen)度下的(de)(de)(de)測量結果進(jin)(jin)(jin)行分(fen)析計算，并(bing)根(gen)據計算結果進(jin)(jin)(jin)行溫(wen)度補(bu)償，同時(shi)剔除零(ling)(ling)(ling)點溫(wen)漂過(guo)大(da)的(de)(de)(de)不(bu)合(he)格的(de)(de)(de)稱重傳(chuan)感器(qi)。

該(gai)巡(xun)檢(jian)系統(tong)主要(yao)分為主控板(ban)(ban)(ban)和檢(jian)測(ce)板(ban)(ban)(ban)兩個(ge)部分，其(qi)中檢(jian)測(ce)板(ban)(ban)(ban)對所連接(jie)(jie)(jie)的(de)(de)稱(cheng)重傳(chuan)感(gan)(gan)器(qi)進行零點輸(shu)出(chu)信號的(de)(de)自(zi)動巡(xun)檢(jian)，并將(jiang)測(ce)量(liang)結果發(fa)送至(zhi)主控板(ban)(ban)(ban)。每(mei)(mei)塊檢(jian)測(ce)板(ban)(ban)(ban)一次最多可以連接(jie)(jie)(jie) 32個(ge)稱(cheng)重傳(chuan)感(gan)(gan)器(qi)，每(mei)(mei)個(ge)傳(chuan)感(gan)(gan)器(qi)連接(jie)(jie)(jie)口都(dou)有(you)(you)固定的(de)(de)ID編(bian)號，檢(jian)測(ce)板(ban)(ban)(ban)可以自(zi)動判斷每(mei)(mei)個(ge)連接(jie)(jie)(jie)口是否(fou)有(you)(you)傳(chuan)感(gan)(gan)器(qi)的(de)(de)連接(jie)(jie)(jie)。每(mei)(mei)塊檢(jian)測(ce)板(ban)(ban)(ban)都(dou)有(you)(you)可設(she)定的(de)(de)獨立ID號，同(tong)時(shi)檢(jian)測(ce)板(ban)(ban)(ban)具有(you)(you)自(zi)診斷功能(neng)，可檢(jian)測(ce)出(chu)AD和RAM等的(de)(de)錯誤。

每塊主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)(ban)(ban)一(yi)(yi)次(ci)最(zui)多可(ke)(ke)以(yi)連接128塊檢(jian)(jian)測(ce)板(ban)(ban)(ban)(ban)(ban)(ban)，因(yin)此該系統最(zui)多可(ke)(ke)以(yi)同(tong)時(shi)巡檢(jian)(jian)4096個稱重傳感(gan)器。每次(ci)開機(ji)時(shi)，主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)(ban)(ban)會自(zi)動查詢(xun)所有(you)已連接的檢(jian)(jian)測(ce)板(ban)(ban)(ban)(ban)(ban)(ban)，當(dang)有(you)無法連接或(huo)有(you)檢(jian)(jian)測(ce)板(ban)(ban)(ban)(ban)(ban)(ban)報(bao)告錯誤時(shi)，主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)(ban)(ban)會在液(ye)(ye)晶屏(ping)上(shang)給出(chu)報(bao)警(jing)提(ti)示(shi)，操(cao)作(zuo)人員(yuan)可(ke)(ke)以(yi)根(gen)據需(xu)要選(xuan)擇停(ting)機(ji)檢(jian)(jian)查，或(huo)者將出(chu)錯的檢(jian)(jian)測(ce)板(ban)(ban)(ban)(ban)(ban)(ban)設定(ding)為停(ting)用(yong)(yong)狀態(tai)，其后(hou)主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)(ban)(ban)將不再與該檢(jian)(jian)測(ce)板(ban)(ban)(ban)(ban)(ban)(ban)進(jin)行數(shu)據通(tong)訊(xun)。主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)(ban)(ban)主(zhu)要完成檢(jian)(jian)測(ce)板(ban)(ban)(ban)(ban)(ban)(ban)數(shu)據采集、檢(jian)(jian)測(ce)數(shu)據分(fen)析計算、與PC機(ji)的數(shu)據通(tong)訊(xun)、打印控(kong)(kong)制和(he)人機(ji)交互等(deng)功能，并同(tong)樣具(ju)有(you)自(zi)診斷功能，當(dang)出(chu)現故障時(shi)系統在液(ye)(ye)晶屏(ping)上(shang)給出(chu)報(bao)警(jing)提(ti)示(shi)，操(cao)作(zuo)人員(yuan)可(ke)(ke)根(gen)據提(ti)示(shi)信息進(jin)行相應(ying)的故障處理。操(cao)作(zuo)人員(yuan)對系統的所有(you)設定(ding)都(dou)可(ke)(ke)通(tong)過主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)(ban)(ban)上(shang)的按鍵完成，主(zhu)控(kong)(kong)板(ban)(ban)(ban)(ban)(ban)(ban)上(shang)還(huan)包括(kuo)一(yi)(yi)塊 16×2的字(zi)符型液(ye)(ye)晶屏(ping)用(yong)(yong)于(yu)顯(xian)示(shi)各(ge)種信息。
