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
