High-precision output air supply pressure difference control pressure sensor

High precision requires the output of air supply pressure difference control pressure sensor High precision requires the output of air supply pressure difference control pressure sensor High precision requires the output of air supply pressure difference control pressure sensor High precision requires the output of air supply pressure difference control pressure sensor dedicated for fire protection positive pressure air supply Pressure difference sensor (economical type) The wind pressure difference sensor is used to control the front room, shared front room, fire elevator front room, and enclosed refuge floor. The normally open contact of the pressure difference controller is closed and the roof bypass is connected. Pressure relief valve control box power supply, 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, and the pressure difference is reduced. When the pressure difference is reduced to At 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.
