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/stairwell of each floor through the shutters/the air valve. when the ventilation pressure/pressure difference in the fire chamber/stairwell exceeds the set value (25 ~ 30 pa in the front chamber&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
