2 Switches, Indicating Gage, and Transmitter in One Package
EDA系列電子壓力控制是一種非常通用的緊湊封裝，可以在一個(gè)系統(tǒng)中取代一個(gè)單獨(dú)的壓力表，兩個(gè)開(kāi)關(guān)，和一個(gè)變送器，節(jié)省資金，安裝時(shí)間，和面板空間。EDA集成了兩個(gè)SPDT繼電器，在控制或報(bào)警使用的范圍內(nèi)，開(kāi)關(guān)點(diǎn)完全可調(diào)。正面有LED指示燈的開(kāi)關(guān)狀態(tài)和一個(gè)大背光兩線顯示過(guò)程值和指示單位。簡(jiǎn)單的菜單結(jié)構(gòu)，兩行顯示和外部編程按鈕，編程容易。耐風(fēng)雨外殼是各種應(yīng)用的理想選擇，具有面板安裝，沖洗安裝，或管道安裝能力。功能包括零點(diǎn)設(shè)置，可調(diào)衰減，菜單鎖定，峰值和山谷指示，可移動(dòng)終端塊，可調(diào)時(shí)間延遲，可縮放發(fā)射機(jī)輸出。

? Display Units: psi, kg/cm?, bar, in Hg, ft w.c., kPa, MPa, %FS, in w.c., mbar, cm w.c., mm Hg, or oz/in? (choices depend on range).
? Test Mode: Simulates input over the range without pressuring to easily test switches and transmitter output feature.
? Fail-safe: For sensor failure, over pressure, high temperature limit, low temperature limit, or keypad short. User chooses if relay is de-energized, energized, or no action. With transmitter option, user chooses an output of 3.6 mA 22 mA, or no action.
? Alternation: Selectable alternation of set points between the relays for even wear on duplex pump applications.
? Versatile Compact Package: Can replace a separate gage, two switches, and a transmitter in a system saving, money, installation time, and panel space.
? Fully Programmable: To meet simple or complex application needs.
? Weatherproof Housing: Ideal for a wide variety of applications with panel mount, flush mount, or pipe mount ability.
