360-degree high-precision exhaust fire positive pressure air supply pressure difference sensor

High-precision exhaust fire-fighting positive pressure supply air pressure difference sensor High-precision exhaust fire-fighting positive pressure supply air pressure difference sensor High-precision exhaust fire-fighting positive pressure supply air pressure difference sensor High-precision exhaust fire-fighting positive pressure supply air pressure sensor Differential sensor, special pressure difference sensor controller for fire positive pressure air supply (economical type). The wind pressure difference sensor controller is used to control the front room, shared front room, fire elevator front room, closed refuge floor. Pressure difference controller normally open contact Close, turn on the power supply of the roof bypass pressure relief valve control box, open the bypass pressure relief valve on the roof to supply air and relieve pressure, and open the bypass pressure relief valve on the roof to supply air and relieve pressure, reducing the pressure difference. value, when the pressure difference drops 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.
