Air Pressure Sensors. Dry media sensors used in applications where you want to measure extremely low pressure such as: building/room pressure, air flow, variable air volume filter status, and duct pressure; Ideal for clean rooms, hospitals, fume hoods and computer rooms; Available in panel mount (P7640A), duct mount (P7640B) and universal mount (P7640U) Drill a 5/16” diameter hole in the duct above the fume hood. Show an indicative location (~2/3’s along the ductwork distribution network) on the design drawings and controls schematic. If the dampers open to increase the airflow to the control zones, the duct pressure will drop, and the fan will speed up to maintain the duct pressure.
