Binary Pressure Sensitive Paint
Another area of interest has been the measurement of surface pressure in low-speed wind tunnels. Binary PSP systems are used in low-speed wind tunnel environments where pressure gradients are small and error sources are more significant. Model shift between reference condition and loaded condition, variation in paint thickness, lamp instability, and temperature are significant sources of error in PSP data. Binary PSP mitigates many of these error sources by employing a second probe into the paint layer, known as the reference probe. This reference probe is used to ratio out the effects of these errors producing high quality PSP pressure maps at low speeds.

Famous quotes containing the words pressure, sensitive and/or paint:
“By school age, many boys experience pressure to reveal inner feelings as humiliating. They think their mothers are saying to them, “You must be hiding something shameful.” And shucking clams is a snap compared to prying secrets out of a boy who’s decided to “clam up.””
—Ron Taffel (20th century)
“The hand I burned and whose skin is shriveled like that of a mummy’s is less sensitive than the other to cold or heat. My soul is the same; it passed through fire.”
—Gustave Flaubert (1821–1880)
“Teaching creativity to your child isn’t like teaching good manners. No one can paint a masterpiece by bowing to another person’s precepts about elbows on the table.”
—Gurney Williams III (20th century)
