樓梯間前室壓力傳感器前室微壓差壓力傳感器安裝位置

消防通風(fēng)系統(tǒng)主要采用壓力傳感器進(jìn)行壓力采樣，壓力傳感器直接將壓力（差）轉(zhuǎn)換為可直接測(cè)量的電量（電壓或電流），通過信號(hào)調(diào)理電路對(duì)傳感器信號(hào)進(jìn)行放大，再通過高速微型處理器（MCU）采集并處理數(shù)據(jù)，輸出控制信號(hào)，并根據(jù)設(shè)定的上下限壓力值（即動(dòng)作壓力及復(fù)位壓力）驅(qū)動(dòng)后部電路（風(fēng)閥控制箱）控制電開關(guān)，開啟或關(guān)閉旁通閥，終實(shí)現(xiàn)壓力（差）控制

電梯前室壓力傳感器

當(dāng)消防前室或樓梯間的通風(fēng)壓力或壓差超過設(shè)定值（前室25~30Pa,樓梯間40-50Pa）時(shí)，Working principle of itive pressure air supply pressure sensor: under normal circumstances, the itive pressure air supply fan pressurizes the air supply into the air shaft through the air duct (Green Arrow Direction) , the compressed air is then sent to the front room or stairwell of each floor through the shutters or the air valve. When the ventilation pressure or pressure difference in the fire chamber or Stairwell exceeds the set value (25 ~ 30 PA in the Front Chamber and 40-50 PA in the stairwell) , the pressure sensor located on each floor immediately sends a signal to the by-pass pressure relief valve control box, the by-pass Pressure Relief Valve control box opens the by-pass pressure relief valve according to the pressure
