产品功能：压差传感器供电功能；压差传感器信号采集功能泄压阀门控制功能消防控制功能消防反馈功能通过压差控制器测量消防门两侧的压差变化，来控制通风管道的旁通泄压阀（对开多页调节阀）的打开和关闭，对消防门两侧的压差进行控制，在楼宇着火时，使老人及小孩能比较轻松打开消防门逃生的同时烟雾不会倒灌进前室和楼梯间。
控制箱|正压送风系统旁通泄压阀控制箱技术参数
1、常规220vac供电（24vdc供电需提前说明）；
2、带两路dc24v直流电源，供压差控制器用电；
3、压差控制器感应消防门两侧压差大小变化，通过控制箱控制旁通泄压阀的打开和关闭；
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，前室压力传感器，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) ，合用前室压力传感器， 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) ，前室压力传感器， 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
压力控制系统可通过控制旁通阀的开闭，将机械加压送风系统的压力值有效控制在要求的合理范围内-----防烟楼梯间40-50Pa，前室、合用前室、消防电梯间前室、封闭避难层(间)为25-30Pa。The pressure control system can effectively control the pressure value of the mechanical pressurization air supply system within the reasonable range required by the national standard-40-50 PA in the ***oke-proof Stairwell by controlling the opening and closing of the by-pass Valve， the front room， the shared front room， the front room of the fire elevator room and the enclosed refuge floor (room) are 25-30Pa.
