寶德(de)BURKERT壓力變送器(qi)操作注意事(shi)項：

1、設(she)備(bei)現場的(de)環境較為惡劣，強(qiang)電(dian)信號會產生各(ge)種電(dian)磁干擾(rao)，雷電(dian)感應(ying)會產生強(qiang)浪(lang)涌脈沖，在這種情(qing)況下(xia)，單片機應(ying)用系統(tong)中(zhong)遇(yu)到的(de)一個棘(ji)手問題就(jiu)是(shi)如何在惡劣環境下(xia)遠距離可靠地(di)傳送微小信號。考慮到變送器高頻噪聲通(tong)過變壓(ya)器主要(yao)不是(shi)靠初、次級線(xian)圈的(de)互感耦合(he)，而是(shi)靠初、次級寄生電(dian)容耦合(he)的(de)，因此隔離變壓(ya)器的(de)初、次級之間均用屏(ping)蔽層隔離，減少其(qi)分布電(dian)容，以提高抵抗共模干擾(rao)能力。

2、但差壓(ya)變送(song)器價格在信號需要遠距離傳(chuan)輸或使(shi)用(yong)環境中電(dian)網干(gan)擾較大的(de)場合，電(dian)壓(ya)輸出型(xing)傳(chuan)感器的(de)使(shi)用(yong)受到(dao)了極(ji)大限制，暴(bao)露了抗(kang)干(gan)擾能(neng)力較差，線(xian)(xian)路損耗破壞(huai)了精(jing)度等等等缺點(dian)，而兩線(xian)(xian)制電(dian)流輸出型(xing)變送(song)器以其具有*的(de)抗(kang)干(gan)擾能(neng)力得到(dao)了廣泛應用(yong)。

3、酸(suan)(suan)堿(jian)(jian)溶液(ye)的(de)濃度(du)與其(qi)電(dian)(dian)(dian)(dian)(dian)導(dao)率(lv)的(de)大小(xiao)成比例。因而，只要測出(chu)溶液(ye)電(dian)(dian)(dian)(dian)(dian)導(dao)率(lv)的(de)大小(xiao)變(bian)可(ke)得知(zhi)酸(suan)(suan)堿(jian)(jian)濃度(du)的(de)高(gao)低。當被測溶液(ye)流入電(dian)(dian)(dian)(dian)(dian)導(dao)池時，如果忽略電(dian)(dian)(dian)(dian)(dian)極極化和分布電(dian)(dian)(dian)(dian)(dian)容，則可(ke)以等效為(wei)一個純電(dian)(dian)(dian)(dian)(dian)阻。在有恒壓(ya)交變(bian)電(dian)(dian)(dian)(dian)(dian)流流過時，其(qi)輸出(chu)電(dian)(dian)(dian)(dian)(dian)流與電(dian)(dian)(dian)(dian)(dian)導(dao)率(lv)成線性關系，而電(dian)(dian)(dian)(dian)(dian)導(dao)率(lv)又與溶液(ye)中酸(suan)(suan)、堿(jian)(jian)濃度(du)成比例關系。因此只要測出(chu)溶液(ye)電(dian)(dian)(dian)(dian)(dian)流，便可(ke)算出(chu)酸(suan)(suan)、堿(jian)(jian)、鹽的(de)濃度(du)。

4、此類故(gu)障(zhang)需要(yao)(yao)更換(huan)放大(da)器(qi)板。變送器(qi)在線(xian)路設計和工(gong)藝裝配質量上要(yao)(yao)求都十分嚴格(ge)，在實際使用中對出現的(de)線(xian)路故(gu)障(zhang)，經檢查確認后與生產廠(chang)家聯系(xi)更換(huan)其故(gu)障(zhang)線(xian)路板，以確保(bao)儀(yi)表長(chang)期工(gong)作的(de)穩定性(xing)和可靠(kao)的(de)差壓變送器(qi)價格(ge)。

5、微(wei)差壓(ya)(ya)變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)(qi)安裝(zhuang)(zhuang)位(wei)(wei)置對零位(wei)(wei)輸出的影響微(wei)差壓(ya)(ya)變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)(qi)由于其(qi)測量范(fan)圍很小，變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)(qi)中傳感(gan)元件的自重(zhong)即(ji)會影響到(dao)微(wei)差壓(ya)(ya)變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)(qi)的輸出，因此在安裝(zhuang)(zhuang)微(wei)差壓(ya)(ya)變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)(qi)出現的零位(wei)(wei)變(bian)(bian)(bian)化情(qing)況屬正常情(qing)況。安裝(zhuang)(zhuang)時應(ying)使變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)(qi)的壓(ya)(ya)力敏感(gan)件軸向垂直于重(zhong)力方向，如果安裝(zhuang)(zhuang)條件限(xian)制，則應(ying)安裝(zhuang)(zhuang)固定后調(diao)整變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)(qi)零位(wei)(wei)到(dao)標準值。

6、我們知道不管什(shen)么型號的(de)差(cha)壓變送器，其正、負壓室(shi)都有(you)排氣、排液閥或旋塞(sai);這(zhe)就(jiu)(jiu)為我們現場(chang)校(xiao)準差(cha)壓變送器提供了(le)方便(bian)，也就(jiu)(jiu)是說(shuo)不用拆除(chu)導(dao)壓管就(jiu)(jiu)可校(xiao)準差(cha)壓變送器。

7、電阻(zu)應(ying)變(bian)片是一(yi)種將被測件上的應(ying)變(bian)變(bian)化轉換成(cheng)為一(yi)種電信(xin)號的敏感器件。它是壓阻(zu)式應(ying)變(bian)變(bian)送器的主要(yao)組(zu)成(cheng)部(bu)分之一(yi)。電阻(zu)應(ying)變(bian)片應(ying)用多的是金屬電阻(zu)應(ying)變(bian)片和半導體應(ying)變(bian)片兩種。
