What is a Pressure Transducer?

•Our pressure transducer is much more precise so we can see very small changes in atmospheric pressure, our readings were every 5 seconds. •The slightest change in pressure will result in not only a change in the graph but also a change in the frequency.

How does a Pitot tube work?

N1639D

A 1952 Cessna 170B pitot tube, yes she still works great!

• Our pressure transducer can compare to a pitot tube in an aircraft.

•They are used to tell pilot’s aircraft speed and some are even used to tell altitude (those are the more fancy ones).

N1639DA more aerodynamic pitot tube.

Future Works

• Different heights, two transducers instead on one.• Air Base, blow stuff up, find pressure when explosions go off. - what a explosion would do to our pressure readings, and what frequencies exert the highest energies. • Longer period’s of time, to collect data, and analysis.• Apply this method of collecting data over a multi-year period in order to

forecast weather trends that may be expected in the future.
