Innovative fire front room intelligent control cabinet, building exhaust micro-pressure differential pressure sensor

Innovative fire protection front room intelligent control cabinet, building exhaust air micro-pressure differential pressure sensor innovative fire protection front room intelligent control cabinet, building exhaust air micro-pressure differential pressure sensor innovative fire protection front room intelligent control cabinet, building exhaust air micro-pressure differential pressure sensor fire protection positive Special pressure difference sensor controller for pressure air supply (economical type). The air pressure difference sensor controller is used to control the front room, shared front room, fire elevator front room, and closed refuge floor. The normally open contact of the pressure difference controller is closed and turned on Turn on the power supply of the control box of the bypass pressure relief valve on the roof. The bypass pressure relief valve on the roof is opened for air supply and pressure relief. The bypass pressure relief valve on the roof is opened for air supply and pressure relief. The pressure difference is reduced. When the pressure When the difference decreases to a certain value, the contacts of the wind pressure difference sensor are disconnected, the bypass valve on the roof is powered off, and the bypass valve is closed to stop pressure relief. Exclusive instrument
Features of the product include
The air bag is used to expand and pull the high-speed elastomer,
so that after reaching the set pressure, the high-speed action switch point is triggered
The air source method makes the sensor controller resistant to overload Strong ability
Mainly used in fire-fighting positive pressure air supply, sensing pressure difference to control pressure relief valve, residual pressure valve action, and used in industrial systems for the purpose of micro pressure difference control. This product is also called positive pressure air supply Sensor, differential pressure measuring and controlling device, wind pressure differential sensor, etc.
