微压差传感器消防前室压力传感器生产商

安装压力传感器的目的是为了为保证疏散通道不受烟气侵害使人员安全疏散，发生火灾时，从安全性的角度出发， 高层建筑内 可分为四个安全区：类安全区为防烟楼梯间、避难层；第二类安全区为防烟楼梯间前室、消防电梯间前室或合用前室；第三类安全区为走道；第四类安全区为房间，我公司前室压力传感器8年之久，我公司是你身边的压力传感，欢迎来人来电咨询，

前室压力探测器

HLB-0161液晶数显压力，可显示现实压力，上下限设置压力，传感器在防排烟系统或正压送风系统中，通常标注为压力传感器，分别用△P或P来表示。压力传感器是一种用来测量两个压力之间差值的传感器，通常用于测量某一设备或部件前后两端的压差。 压力传感器是能感受压力信号，并能按照一定的规律将压力信号转换成可用的输出的电信号的器件或装置。

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
