防爆ATEX/IECEx外殼中的ADPS
AT-ADPS ATEX/IECEx系列認(rèn)可的壓差開關(guān)設(shè)計(jì)用于危險(xiǎn)區(qū)域的壓力、真空和壓差應(yīng)用。英寸水柱和帕斯卡的雙刻度調(diào)節(jié)旋鈕允許在沒有壓力表的情況下改變開關(guān)壓力。該開關(guān)的設(shè)置范圍從0.08 in w.c.(20 Pa)到20 in w.c.(5000 Pa)。硅膠隔膜使這個(gè)系列非常適合與空氣和其他不可燃?xì)怏w一起使用。防火外殼由鋁制成,可包括一個(gè)玻璃窗,用于查看調(diào)節(jié)旋鈕上的設(shè)定點(diǎn)狀態(tài)。
安裝注意事項(xiàng):
電纜必須通過1/2“NPT電纜密封套或ATEX/IECEx導(dǎo)管安裝(不隨儀表提供)。確保布線后關(guān)閉密封蓋和電纜密封套,以保持IP66等級(jí)。僅在儀器斷電后打開蓋子。注意:檢查當(dāng)?shù)氐陌踩?guī)則和警告以及裝置和手冊(cè),以便在危險(xiǎn)區(qū)域正確使用儀表。
