Sensym in Santa Clara ( area code 408 ) makes different kind of pressure sensors, get their data book, they also have application notes on building digital barometers

Try also OMEGA 1-800-222-2665 and ask for their PRESSURE STRAIN AND FORCE catalog. Model PX 136-015A V is a small (.6"square) absolute pressure sensor with excellent performance. Output is linear: 0 to 100mv for 0-15psi. $56 Model PX 142-015A 5V is larger (1.2"x2.4"), and senses absolute pressure from 0-15psi as well. Its output is linear from 1 to 6V. $94 There are many, many more nifty pressure sensing devices of all sorts in the catalog. I mentioned these only because they are relatively inexpensive and detect absolute pressure, and because I already had the pages marked because I was gonna use one, too! David
