如何正確的選擇抄表方案
2024-01-11 841
抄(chao)(chao)(chao)表(biao)(biao)方(fang)案在水電(dian)等能(neng)(neng)源企業中具(ju)有不可忽視(shi)的(de)(de)作用，主要分為有線(xian)智(zhi)能(neng)(neng)抄(chao)(chao)(chao)表(biao)(biao)方(fang)案和無線(xian)智(zhi)能(neng)(neng)抄(chao)(chao)(chao)表(biao)(biao)方(fang)案。??????其中，有線(xian)智(zhi)能(neng)(neng)抄(chao)(chao)(chao)表(biao)(biao)方(fang)案中，RS-485抄(chao)(chao)(chao)表(biao)(biao)方(fang)案是最常用的(de)(de)方(fang)式。它通過RS485傳(chuan)輸線(xian)將多臺(tai)RS485接(jie)口電(dian)表(biao)(biao)直(zhi)接(jie)與集(ji)中器連(lian)接(jie)，形成數據(ju)(ju)傳(chuan)輸網絡。此(ci)方(fang)案適用于電(dian)表(biao)(biao)集(ji)中安(an)裝(zhuang)的(de)(de)場(chang)合(he)，具(ju)有數據(ju)(ju)傳(chuan)輸穩定性高(gao)、速度快、電(dian)表(biao)(biao)價格(ge)實惠、集(ji)中器投入較(jiao)少等優點。此(ci)外，它還(huan)具(ju)有數據(ju)(ju)準確度高(gao)、抗干(gan)擾能(neng)(neng)力強等特性。????...

電磁水表為什么這么貴

電磁(ci)水(shui)(shui)(shui)表(biao)之所以(yi)(yi)價格(ge)較(jiao)(jiao)高，主要(yao)(yao)是由以(yi)(yi)下(xia)幾個(ge)方面的(de)(de)原因(yin)導致的(de)(de)：??????首先，制(zhi)(zhi)造(zao)工藝復雜(za)是電磁(ci)水(shui)(shui)(shui)表(biao)價格(ge)較(jiao)(jiao)高的(de)(de)一(yi)個(ge)重(zhong)要(yao)(yao)因(yin)素。由于水(shui)(shui)(shui)的(de)(de)特(te)(te)殊(shu)性質，電磁(ci)水(shui)(shui)(shui)表(biao)的(de)(de)傳感器和(he)變送器需(xu)要(yao)(yao)經過(guo)特(te)(te)殊(shu)設(she)計和(he)制(zhi)(zhi)造(zao)，以(yi)(yi)確保(bao)其在(zai)各(ge)種水(shui)(shui)(shui)質和(he)溫度條件(jian)下(xia)都能(neng)正常工作。此外，電磁(ci)水(shui)(shui)(shui)表(biao)的(de)(de)顯示部(bu)分也需(xu)要(yao)(yao)進行特(te)(te)殊(shu)設(she)計，以(yi)(yi)便能(neng)夠(gou)清晰地顯示流量信息。這(zhe)種復雜(za)的(de)(de)制(zhi)(zhi)造(zao)工藝使得(de)電磁(ci)水(shui)(shui)(shui)表(biao)的(de)(de)制(zhi)(zhi)造(zao)成本相對(dui)較(jiao)(jiao)高。??????其次，電磁(ci)水(shui)(shui)(shui)表(biao)的(de)(de)應用范圍更廣，這(zhe)也...
