ive been looking for something that I can attach to an air line and read th= e pressure out, analog voltage is probably whats available. My searches ke= ep putting me back to barometric sensors. The idea is to replace a mechani= cal gauge since I have a LCD and pic micro in the unit. The range is a 0-9= 0PSI that I need to cover. Im sure they make them, just haven't come across anything yet. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
