產品描(miao)述：
可(ke)以現場(chang)編(bian)程(cheng)選擇(ze)測量(liang)壓(ya)力、風(feng)速或流(liu)量(liang)
DM-1000系(xi)列數字差(cha)壓(ya)表(biao)/風速表(biao)是(shi)替(ti)換模擬(ni)機(ji)械式差(cha)壓(ya)表(biao)及(ji)風(feng)速(su)表(biao)的的數字式(shi)儀表(biao)。同(tong)模(mo)擬(ni)表(biao)相比，數字表(biao)具有(you)更(geng)強(qiang)大靈(ling)活(huo)的功能，諸如可以現場(chang)編(bian)程(cheng)選擇(ze)測量(liang)壓(ya)力、風(feng)速或流(liu)量(liang)。此(ci)外DM-1000系(xi)列數字式差(cha)壓(ya)表(biao)還具備壹個特性，因其(qi)具有(you)報(bao)警(jing)設(she)定點(dian)，特別(bie)適(shi)用(yong)於(yu)有(you)過(guo)濾(lv)器的(de)應用場(chang)合(he)，當過(guo)濾(lv)器臟(zang)了後(hou)，DM-1000將會閃爍(shuo)報(bao)警(jing)，提醒(xing)客(ke)戶(hu)需要進(jin)行(xing)維護等操作。
    對(dui)DM-1000系(xi)列進(jin)行(xing)編(bian)程(cheng)，僅僅需要(yao)通(tong)過(guo)菜單鍵(jian)進(jin)入(ru)4個(ge)醒目的子菜單(dan)，通(tong)過(guo)它(ta)們(men)可以設(she)定安(an)全等級(ji)、選擇工(gong)程(cheng)單位、更改(gai)K系(xi)數(shu)（當使用(yong)不(bu)同(tong)的(de)皮(pi)托(tuo)管(guan)或流(liu)量(liang)傳感(gan)器(qi)時）、設定圓形或方形管(guan)道尺(chi)寸(cun)（測量體(ti)積(ji)流(liu)量(liang)時(shi)）、更改(gai)過(guo)濾(lv)器設(she)定點(dian)、查看zui高/zui低峰值(zhi)數據(ju)、設定數(shu)字阻(zu)尼值(zhi)用來平滑讀(du)數（用(yong)於(yu)讀(du)數(shu)波(bo)動較多(duo)的過(guo)程(cheng)應用）、顯示(shi)模(mo)式（用以節(jie)省電(dian)池(chi)），現場(chang)校(xiao)準(zhun)零(ling)點(dian)及(ji)量(liang)程(cheng)。
     DM-1000系(xi)列數字式差(cha)壓(ya)表(biao)/風速表(biao)，具有(you)1%FS的(de)精(jing)度（量程(cheng)大於(yu)2? W.C）及(ji)2%精(jing)度（量程(cheng)0.25? W.C到(dao)1? W.C）。DM-1000具有(you)多(duo)種供電(dian)方式(shi)，可以使(shi)用9-24VDC電(dian)源模(mo)塊(kuai)供(gong)電(dian)，也可以使(shi)用9V電(dian)池(chi)供電(dian)。而(er)當使用(yong)電(dian)源模(mo)塊(kuai)供(gong)電(dian)且(qie)儀(yi)表(biao)具有(you)9V電(dian)池(chi)時，電(dian)池(chi)將起(qi)到(dao)備份的作用，即當停電(dian)時(shi)9V電(dian)池(chi)將自(zi)動啟動，使儀(yi)表(biao)繼續正(zheng)常運(yun)行(xing)。
