The OPN-DR measures air pressure differences between inside and outside of the barn. To get a fresh air flow in the barn, the air pressure in the house must be lower than the air pressure outside. The pressure difference is converted to a 4-20 mA signal. Based on that, the inside negative pressure can control the ventilation system.
