前室微压差传感器

我司专门为正压送风系统（前室，楼梯间，地下避难所等）压差控制开发的一款产品，高稳定传感器，报警指示灯显示；外壳采用壁挂方式；前端采用直径6mm压迫式阶梯管，使用方便，连接可靠，的放大线路，严格的生产制作工艺，完善的检验及老化测试设备，确保了优异的产品品质。该产品广泛的应用前室（合用前室）压差测控系统、封闭避难层、防烟楼梯间压差测控系统；室内外压差检测、过滤网堵塞监控系统等干燥气体的压差测控系统。

前室压力控制器

电梯前室通常要求其空间内部气压高于外部气压 10~15Pa ;而高层建筑前室(包括消防电梯前室、楼梯间前室、合用前室、三合一前室、共用前室等)要求是25~30Pa，楼梯间要求是 40~50Pa

电梯前室压力传感器

当消防前室或楼梯间的通风压力或压差超过设定值（前室25~30Pa,楼梯间40-50Pa）时，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
