43000系列 Capsu-Photohelic 液用差壓表 開關(guān)-德威爾Dwyer
43000系列Capsu-Photohelic®液用差壓表/開關(guān) 組合了多功能,高重復(fù)性的開關(guān)和高精度的差壓表,差壓表采用了我們可靠耐用的Magnehelic差壓表的設(shè)計(jì)理念。Capsu-Photohelic®液用差壓表/開關(guān)采用膜盒傳感器,能夠監(jiān)測液體和氣體的壓力到500 psig(34bar)。可選鑄銅材質(zhì)用于水或水基液體。帶有兩個(gè)光電感應(yīng)的雙刀雙擲開關(guān)用于高/低限位控制。直接通過面板上的旋鈕就很方便的改變?cè)O(shè)定點(diǎn)。每個(gè)單獨(dú)設(shè)定點(diǎn)的回差小于滿刻度的1% ,兩個(gè)設(shè)定點(diǎn)可以交互成為一個(gè)可調(diào)節(jié)的盲區(qū),適用于水泵控制等應(yīng)用場合。
