Where should the primary static air pressure sensor be mounted inside a tunnel-ventilated layer house to control fan stages?

In modern, climate-controlled tunnel houses, ventilation is managed by maintaining a precise static pressure (typically between 15 to 25 Pascals). This negative pressure ensures that air enters through the cooling pads at high velocity, creating a uniform mixing pattern. The primary static pressure sensor must be mounted on a solid interior wall in the middle of the house length (usually 30 to 40 meters upstream from the exhaust fans). It must be placed away from personnel entry doors, exhaust fans, or air inlets, as local drafts can cause false readings and trigger unnecessary fan changes. The outdoor reference tube of the sensor must also be shielded from wind. Engineers can study ventilation thermodynamics in the Poultry Encyclopedia, purchase digital static pressure gauges on Poultry Plaza, monitor daily feed conversion rates on Poultry Rates, and trade shed machinery on Murghi Mandi.
