A-306

A-306 is an outdoor static pressure sensor, includes 50' vinyl tubing, mounting bracket and hardware. A-306 static pressure sensor effectively reduces the fluctuation of outdoor static pressures as caused by wind gusts. Elimination of this factor is critical in the control of building pressures which use outdoor static pressure as a reference. In planning a building HVAC (Heating, Ventilation and Air Conditioning) system, consideration should be given to both location of the outdoor static pressure sensor and interior location of controls which reference outside pressure. In addition to building return or exhaust fan controls, zone return air dampers, if used, require a stable reference pressure.
