Air duct differential pressure sensor WH201 air duct differential pressure sensor of Wanhe Zhongyi

WH201 air duct differential pressure sensor

Applied to fire staircases, elevator front rooms, shared front rooms, enclosed refuge floors, and ventilation system pressure or pressure difference control. The power supply of the roof bypass pressure relief valve control box is connected through the output signal of the staircase pressure sensor. The bypass pressure relief valve on the roof is opened for air supply and pressure relief, reducing the pressure or pressure difference. When the pressure or pressure difference decreases to a certain value, the contact of the staircase pressure sensor is disconnected, and the control of the roof bypass valve is powered off, The bypass valve closes to stop pressure relief.
