(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(shí)測(cè)量出靜壓、溫度變化對(duì)檢測(cè)元件的影響，通過數(shù)據(jù)處理，對(duì)非線性進(jìn)行校正，對(duì)滯后及復(fù)現(xiàn)性進(jìn)行補(bǔ)償，使得輸出信號(hào)更精確。一般情況，精度為比較大量程的±0.1%，數(shù)字信號(hào)可達(dá)±0.075% </p> <p> (2)功能強(qiáng) </p> <p> 智能變送器具有多種復(fù)雜的運(yùn)算功能，依賴內(nèi)部微處理器和存儲(chǔ)器，可以執(zhí)行開方、溫度壓力補(bǔ)償及各種復(fù)雜的運(yùn)算。 </p> <p> (3)測(cè)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(dá)40:1或100:1，遷移量可達(dá)1900%和-200%，減少變送器的規(guī)格，增強(qiáng)通用性和互換性，給用戶帶來諸多方便。 </p> <p> (4)通信功能強(qiáng) </p> <p> 智能變送器均可實(shí)現(xiàn)手操器進(jìn)行操作，既可在現(xiàn)場(chǎng)將手操器插到變送器的相應(yīng)插孔，也可以在控制室將手操器連接到變送器的信號(hào)線上，進(jìn)行零點(diǎn)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?jī)煞N輸出方式(如HART協(xié)議)，為實(shí)現(xiàn)現(xiàn)場(chǎng)總線通訊奠定了基礎(chǔ)。成都數(shù)字智能顯示儀表哪家好</p><div

1、儀表尺寸。即儀表的體積大小，這是個(gè)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(kuò)充性較強(qiáng)，同樣功能價(jià)格可能會(huì)貴，體積小的儀表可能功能擴(kuò)充性較差。目前數(shù)顯表面板的國(guó)際標(biāo)準(zhǔn)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(cè)量精度，一般來講，顯示位數(shù)越高，測(cè)量更精確，價(jià)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(jì)數(shù)器、累計(jì)表和**儀表)，用戶可以根據(jù)測(cè)量精度要求來選擇幾位的數(shù)顯表。 </p><p> 智能儀表 </p> <p> 1.**初的智能儀表被稱為自動(dòng)抄表系統(tǒng)（AMR），也是遠(yuǎn)程自動(dòng)抄表也成為了智能儀表**基本的功能。利用智能儀表的紅外線等通信功能，就能夠?qū)崿F(xiàn)自動(dòng)抄表。這樣就不需要工作人員前往現(xiàn)場(chǎng)進(jìn)行人工抄表，提升了效率，也削減抄表業(yè)務(wù)的成本。此外，還能夠減少人為因素造成的失誤，抄表精度得到提升，也使得收益得到提升。之后雙向通信的遠(yuǎn)程操作功能也增加進(jìn)來，防止非法使用電力/燃?xì)獾龋虼酥悄軆x表**初被能源行業(yè)應(yīng)用和看好。

style="text-indent:25px">輸入信號(hào)。指直接輸入儀表的測(cè)量信號(hào)，有些工業(yè)信號(hào)是直接接入儀表測(cè)量的，有些信號(hào)是經(jīng)過轉(zhuǎn)化后接入儀表的，必須弄清楚測(cè)量信號(hào)的性質(zhì)，否則買去的儀表不能用，甚至損壞儀表及原有設(shè)備。要弄清信號(hào)類型：電流還是電壓，交流還是直流，是脈沖信號(hào)還是線性信號(hào)等等，還要弄清信號(hào)的大小。儀表的名稱與輸入信號(hào)不是同一概念，舉幾個(gè)例子：輸入信號(hào)是0-75mVdc的電流表(名稱是電流表，輸入信號(hào)卻是電壓信號(hào)，因?yàn)殡娏鹘?jīng)過分流器取得電壓信號(hào));輸入信號(hào)是0-10Vdc的轉(zhuǎn)速表(名稱是轉(zhuǎn)速表，輸入信號(hào)卻是電壓表，因?yàn)樽冾l器將轉(zhuǎn)速信號(hào)轉(zhuǎn)化成電壓信號(hào))。成都數(shù)字智能顯示儀表報(bào)價(jià)</p><p
