电梯前室压力传感器消防压力传感器生产商

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

when the supply air volume&time of itive pressure air supply system is out of control, the normal escape route may be too high because of the itive pressure of the front room, the fire door can not open the serious cequences. in view of the above ciderati, the sichuan institute of fire science combined with experience to provide data of residual pressure value. by controlling the opening&closing of the by-pass valve, the differential control system can effectively control the residual pressure of the mechanical pressurized air supply system within the reasonable range required by the national standard ——40-50 pa in the smoke-proof stairwell, the front room, the shared front room, the front room of the fire elevator room&the enclosed refuge floor (room) are 25-30pa.
