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))。</p><p> 如何選型 </p> <p> 智能儀表規(guī)格 </p> <p> 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。
