Do you mean a pressure transducer, such that it converts the air pressure into a voltage, which you can feed back to the Robot Controller, and read out on the Operator Interface? If so, you can find one in the 2004 Kit of Parts (I believe 1323's rookie year was 2004, otherwise, you may want to locate a nearby team with a team number less than 1200, they should have one.)
