电梯前室压力传感器楼梯间压力传感器批发

本公司研发加工制作前室正压传感器，可定做可贴牌可代工。

微压差压力传感器其广泛应用于各种工业自控环境，下面就简单介绍一些常用传感器原理及其应用。

1、型号不同测量的参数不同：电梯前室压力传感器测量相对压力，即两个部位的压力差。

2、接口：余压传感器有两个输入管口分别用于连接两个测点；压力传感器只有一个连接管口。

3，除微压差开关只用两根信号线外，其它传感器全部为四线制，两根电源线，两根信号线。

4，线速不得低于1.52

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)

The type pressure difference controller is widely used in the pressure difference measurement and control system of the front room (the Common Front Room) , the closed refuge floor and the smoke-proof Stairwell Indoor and outdoor pressure difference detection, filter plug monitoring system and other dry gas pressure difference measurement and control system.

通用型压差控制器广泛应用于前室（合用前室）压差测控系统、封闭避难层、防烟楼梯间压差测控系统；室内外压差检测、过滤网堵塞监控系统等干燥气体的压差测控系统。
