前室压力传感器

电子式压力传感器的是压差传感器，传感器通过两个气压探测口，引压至压力传感器，其作用力作用于传感器内部的晶圆结构，从而改变传感器电容，再利用电子线路检测这一变化，并通过A/D转换器(模拟量转数字量)，将相对应力即压差值，转换为一个标准电子信号，再经微处理器根据逻辑设定，进行电信号输出。电子式压力传感器的是压差传感器，传感器通过两个气压探测口，引压至压力传感器，其作用力作用于传感器内部的晶圆结构，从而改变传感器电容，再利用电子线路检测这一变化，并通过A/D转换器(模拟量转数字量)，将相对应力即压差值，转换为一个标准电子信号，再经微处理器根据逻辑设定，进行电信号输出。

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

加压后的风再分别通过每层的百叶窗或风阀送往每层的前室或楼梯间。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，位于每层的压力传感器顺即时发出信号报警输入旁通泄压阀控制箱，旁通泄压阀控制箱根据压力传感器的信号打开旁通泄压阀，旁通泄压阀打开后，部分加压送风机送往风管的风通过旁路风管经过旁通泄压阀回到风机前端（红色箭头位置）
































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 signal of the pressure sensor, part of the pressurized air supply fan to the air duct through the Bypass Air Duct by-pass Relief Valve back to the Fan Front (Red Arrow ition)
