前室压力探测器消防楼梯间前室压力传感器批发

压力传感器主要用于监测与控制两个不同空间的空气压力差值。常见于安装有正压送风系统的环境，例如无尘车间、实验室、及高层建筑电梯前室、楼梯间及地下车库等。使用环境不同，其技术要求也不尽相同。像无尘车间、实验室，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
