1、儀表尺寸。即儀表的體積大小，這是個(gè)很基本的問(wèn)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(guò)大了可能裝不下，過(guò)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(lái)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，瀘州數(shù)字智能顯示儀表價(jià)格，極少);三位半(1999，瀘州數(shù)字智能顯示儀表價(jià)格，瀘州數(shù)字智能顯示儀表價(jià)格，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(jiàn)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(lái)選擇幾位的數(shù)顯表。瀘州數(shù)字智能顯示儀表價(jià)格</p><div
