(1)精度高智能變送器具有較高的精度。利用內(nèi)裝的微處理器，能夠?qū)崟r測量出靜壓、溫度變化對檢測元件的影響，通過數(shù)據(jù)處理，對非線性進行校正，對滯后及復(fù)現(xiàn)性進行補償，使得輸出信號更精確。一般情況，精度為比較大量程的±0.1%，數(shù)字信號可達±0.075% </p> <p> (2)功能強 </p> <p> 智能變送器具有多種復(fù)雜的運算功能，依賴內(nèi)部微處理器和存儲器，可以執(zhí)行開方、溫度壓力補償及各種復(fù)雜的運算。 </p> <p> (3)測量范圍寬 </p> <p> 普通變送器的量程比比較大為10:1，而智能變送器可達40:1或100:1，遷移量可達1900%和-200%，減少變送器的規(guī)格，增強通用性和互換性，給用戶帶來諸多方便。 </p> <p> (4)通信功能強 </p> <p> 智能變送器均可實現(xiàn)手操器進行操作，雅安數(shù)字智能顯示儀表，既可在現(xiàn)場將手操器插到變送器的相應(yīng)插孔，雅安數(shù)字智能顯示儀表，雅安數(shù)字智能顯示儀表，也可以在控制室將手操器連接到變送器的信號線上，進行零點及量程的調(diào)校及變更。有的變送器具有模擬量和數(shù)字量兩種輸出方式(如HART協(xié)議)，為實現(xiàn)現(xiàn)場總線通訊奠定了基礎(chǔ)。雅安數(shù)字智能顯示儀表</p><div

不同地電位引入的干擾。在大功率的用電設(shè)備附近，當(dāng)設(shè)備的絕緣性能較差時，不同地電位的電位差的引入形成干擾，而在儀表的使用中往往會有意無意地使輸入端存在兩個以上的連接點，這樣就會把不同接地點的電位差以共模干擾形式引入到儀器儀表，這種干擾是同時出現(xiàn)在兩信號線上的。 </p> <p> <p> 脈沖干擾電壓 </p> <p> 一些脈沖狀的干擾電壓除能作用于模擬電路外，有時也能直接進入數(shù)字電路中給予干擾，這些干擾電壓的發(fā)生源是開關(guān)、電機、繼電器那樣的感性負載和產(chǎn)生放電的機器等。 </p> </p> <p> <br /> 樂山數(shù)字智能顯示儀表推薦</p><div style="width:100%;text-align: center;"><img

</p> <p> 1、儀表尺寸。即儀表的體積大小，這是個很基本的問題。數(shù)顯表要裝在柜體上，所以要考慮整體的協(xié)調(diào)性，過大了可能裝不下，過小了看不清顯示數(shù)字，另外，體積大的儀表一般功能擴充性較強，同樣功能價格可能會貴，體積小的儀表可能功能擴充性較差。目前數(shù)顯表面板的國際標準尺寸主要有以下幾種：48*24mm；48*48mm；48*96mm；72*72mm；96*96mm；96*48mm；160*80mm。 </p> <p> 2、顯示位數(shù)。這直接關(guān)系到數(shù)顯表的測量精度，一般來講，顯示位數(shù)越高，測量更精確，價格也越貴，主要有以下幾種：兩位(99，特殊);三位(999，極少);三位半(1999，普通數(shù)顯表占主流);四位(9999，智能數(shù)顯表占主流);四位半(19999);四又四分之三(3999);五位及五位以上(常見于計數(shù)器、累計表和**儀表)，用戶可以根據(jù)測量精度要求來選擇幾位的數(shù)顯表。 </p><p style="text-indent:25px">儀表功能。儀表功能一般都是模塊化的，可選擇的，儀表價格也會隨功能不一樣而有所差異，數(shù)顯表主要有以下可選功能：報警功能及報警輸出的組數(shù)(即繼電器動作輸出)，饋電電源輸出及輸出電壓的大小及功率，變送輸出及變送輸出的類型(4-20mA還是0-10V等)，通訊輸出及通訊方式和協(xié)議(RS485還是RS232，是Modbus還是其他協(xié)議)，對于調(diào)節(jié)控制儀表，可選功能就更多，具體要參照廠家的選型譜選出一個規(guī)范的型號，并與廠家溝通并確認無誤后才可以訂貨。</p><div

指電的耦合，靜電感應(yīng)是兩電場相互作用的結(jié)果。在相對的兩根導(dǎo)線中，如其一的電位發(fā)生變化，則由于導(dǎo)線間的電容變化使得另一導(dǎo)線的電位也發(fā)生變化，干擾源以電容性的耦合在回路中形成干擾。 </p> <p> 電勢 </p> <p> 附加熱電勢和化學(xué)電勢。由于不同金屬產(chǎn)生的熱電勢以及金屬腐蝕等產(chǎn)生的化學(xué)電勢，在電路回路中形成直流電氣干擾。 </p> <p> <p> 震動 </p> <p> 在強振動的環(huán)境中，導(dǎo)線由于在磁場中處于運動狀態(tài)而產(chǎn)生感應(yīng)電勢，此干擾與信號相串聯(lián)，以串模干擾形式進入儀器儀表。 </p>

微電子技術(shù)和計算機技術(shù)的不斷發(fā)展，引起了儀表結(jié)構(gòu)的根本性變革，以微型計算機（單片機）為主體，將計算機技術(shù)和檢測技術(shù)有機結(jié)合，組成新一代“智能化儀表”，在測量過程自動化、測量數(shù)據(jù)處理及功能多樣化方面與傳統(tǒng)儀表的常規(guī)測量電路相比較，取得了巨大進展。 </p> <p> 智能儀表不僅能解決傳統(tǒng)儀表不易或不能解決的問題，還能簡化儀表電路，提高儀表的可靠性，更容易實現(xiàn)高精度、高性能、多功能的目的。隨著科學(xué)技術(shù)的進一步發(fā)展，儀表的智能化程度將越來越高。智能儀表，不但能完成多種物理量的精確顯示，同時可以帶變送輸出、繼電器控制輸出、通訊、數(shù)據(jù)保持等多種功能。 </p> <p> 智能儀表和智能傳感器一般是用在現(xiàn)場總線系統(tǒng)中，這種儀表和傳感器內(nèi)部嵌入的有通訊模塊和控制模塊，可以完成數(shù)據(jù)采集，數(shù)據(jù)處理和數(shù)據(jù)通訊功能,說白了就是在普通的儀表和傳感器上加了個單片機。 </p> <p> <br /> 雅安數(shù)字智能顯示儀表</p><p
