FAQs:
Q: What is the Dwyer A-306 Outdoor Static Pressure Sensor used for?
A: The Dwyer A-306 provides an outdoor static pressure reference for building pressurization controls. It helps reduce fluctuations in the outdoor pressure reference caused by wind gusts, which is important when outside pressure is used to control building pressure.
Q: Where is the Dwyer A-306 commonly used in an HVAC system?
A: The A-306 is intended for building HVAC pressure-control applications. Building return or exhaust fan controls and systems with zone return air dampers may require a stable outdoor pressure reference.
Q: What comes with the Dwyer A-306?
A: The A-306 includes the outdoor static pressure sensor, 50 feet of vinyl tubing, a mounting bracket, and mounting hardware.
Q: What size tubing does the Dwyer A-306 use?
A: The A-306 uses 1/8-inch vinyl tubing. The kit includes a 50-foot length for connecting the sensor to the building pressure-control system.
Q: Where should the Dwyer A-306 be located?
A: The sensor should be positioned outdoors in an area as free as possible from rooftop obstructions and other sources of air turbulence. Trees, chimneys, signs, and buildings can create turbulence that can affect the outdoor static pressure reading.
Q: What is the difference between the Dwyer A-306 and A-306-A?
A: The models serve the same basic outdoor static pressure-reference application, but the manufacturer identifies the A-306 as the red sensor and the A-306-A as the gray sensor.
