style="text-indent:25px">數(shù)顯儀表產(chǎn)生干擾的途徑：信號源與儀表之間的導(dǎo)線、內(nèi)部配線通過磁耦合在電路中形成干擾。在大功率變壓器、交流電機、電力線的周圍空間都存在有很強的交流磁場，而閉合回路處在這種變化的磁場中將產(chǎn)生電動勢。這種感應(yīng)電勢與有用信號串聯(lián)，當(dāng)傳感器與數(shù)顯表距離較遠時，這種串模干擾特別突出。干擾源通過電容的耦合在回路中形成干擾，是由于兩電場相互作用的結(jié)果。通過靜電耦合的方式，能在兩輸入端感應(yīng)出對地的共同電壓，以共模干擾的形式出現(xiàn)，由于共模干擾不和信號相疊加，它不直接對儀表產(chǎn)生影響。但它能通過測量系統(tǒng)形成到地的泄漏電流，該泄漏電流通過電阻的耦合就能直接作用于儀表而產(chǎn)生干擾。電磁感應(yīng)、靜電感應(yīng)所形成大多是工頻干擾電壓，但變頻器、帶整流子的電機等會產(chǎn)生諧波干擾。廣元數(shù)顯儀表推薦廠家</p><div

style="text-indent:25px">幾個比較重要的參數(shù)要關(guān)注一下：測量精度(值越小越***)、響應(yīng)速度(值越小響應(yīng)越快)、工作環(huán)境、溫度系數(shù)(值越小受溫度影響越小)、過載能力。特殊要求：若用戶有特殊要求就應(yīng)提出來，讓廠家確認能否滿足要求，千萬不能想當(dāng)然，比如：ip防護等級、高溫工作場合、強干擾場合、特殊信號場合、特殊工作方式等等。其實，數(shù)顯表選型并不復(fù)雜，對于簡單的數(shù)顯表一般買過來就可以用了，對于初次使用或選用功能復(fù)雜數(shù)顯表的用戶只要把握了要素，也能很好的選購到合適的產(chǎn)品</p><p style="text-indent:25px">常見問題：通電后缺筆或顯示亂碼可能原因：缺筆基本上為虛焊問題。直接換表。亂碼：1.有干擾源，如大容量開關(guān)合閘時會造成對儀表的沖擊，使多功能表進入設(shè)置界面，而非亂碼。此時儀表會在30秒內(nèi)恢復(fù)，或按SET恢復(fù)正常。2.芯片故障：芯片故障率一般為千分之一以下;3.芯片虛焊或漏焊。解決方法：前者與客戶溝通，不成，換表(在電源前端作相應(yīng)處理)，后二都直接換表。常見問題：顯示不準確可能原因：互感器變比設(shè)置數(shù)值不匹配解決方法：將儀表設(shè)置的變比與PT、CT的變比核對是否一致;電壓、電流的額定值是否一致。</p><div

style="text-indent:25px">儀器儀表行業(yè)本身是一個投入，產(chǎn)出周期較長的行業(yè)，所以作為業(yè)內(nèi)廠家，一方面要尋找中、短期市場熱點，另一方面也要在產(chǎn)品、技術(shù)研發(fā)方面有長遠的規(guī)劃;一些中低檔產(chǎn)品已具有規(guī)模優(yōu)勢和國際市場競爭力。中國已成為[ "耐磨熱電偶", "氣體檢測儀器", "便攜式氣體報警控制器", "雙金屬溫度計" ]等產(chǎn)品的生產(chǎn)和出口大國，其他儀器設(shè)備等產(chǎn)品的出口也開始取得突破。目前我國研發(fā)、銷售計算機軟硬件;計算機系統(tǒng)集成;銷售電子產(chǎn)品、儀器儀表、電氣設(shè)備、機械設(shè)備、閥門、水泵、電線電纜、通訊器材(不含無線廣播電視發(fā)射及衛(wèi)星地面接收設(shè)備)、醫(yī)療器械(***一類)、實驗設(shè)備、化工產(chǎn)品(不含危險化學(xué)品)、五金交電、照明設(shè)備。產(chǎn)品，主要集中在中低檔市場，而**市場則主要被國外品牌所占據(jù)。在某些**領(lǐng)域，國產(chǎn)產(chǎn)品甚至是空白，這就需要未來我國儀器儀表向**市場進軍，擴大***產(chǎn)品占有率。銷售專業(yè)化發(fā)展是中國儀器儀表產(chǎn)業(yè)的又一發(fā)展趨勢，隨著科技水平的提高，儀器儀表產(chǎn)品不*用在日常的測量、調(diào)節(jié)、測溫、顯示等設(shè)備中，而且開始運用在不同的領(lǐng)域之中。廣元數(shù)顯儀表推薦廠家</p><p
