保特potter開(kāi)關(guān)接在閥門(mén)水流報(bào)警接口配管上，根據(jù)水流監(jiān)測(cè)閥門(mén)是否開(kāi)啟。僅需一個(gè)灑水頭動(dòng)作的流量壓力開(kāi)關(guān)就可動(dòng)作。在預(yù)作用系統(tǒng)中接在閥門(mén)出口處，監(jiān)測(cè)系統(tǒng)管道中氣壓，當(dāng)氣壓降低時(shí)，發(fā)出低氣壓報(bào)警信號(hào)。動(dòng)作壓力能在4-20psi (0.28-1.38bar) 之間調(diào)節(jié)。開(kāi)關(guān)必須直立安裝。 保特PS10A 系列是壓力型水流探測(cè)開(kāi)關(guān)，分為PS10-1A ( 含一副SPDT 接點(diǎn))，PS10-2A( 含二副SPDT 接點(diǎn))，在濕式、干式和預(yù)作用系統(tǒng)中。The Potter PS10 Series Pressure Actuated Switches are designed for the detection of a waterflow condition in automatic fire sprinkler systems of particular designs such as wet pipe systems with alarm check valves, dry pipe, preaction, or deluge valves. The PS10 is also suitable to provide a low pressure supervisory signal; adjustable between 4 and 15 psi (0,27 and 1,03 BAR).
Potter PS10系列壓力驅(qū)動(dòng)開(kāi)關(guān)設(shè)計(jì)用于檢測(cè)特定設(shè)計(jì)的自動(dòng)噴水滅火系統(tǒng)中的水流狀況，例如帶報(bào)警止回閥，干管，預(yù)作用或雨淋閥的濕管系統(tǒng)。FM認(rèn)證壓力開(kāi)關(guān) PS10也適用于提供低壓監(jiān)控信號(hào); 可在4到15 psi（0,27和1,03 BAR）之間調(diào)節(jié)。
