Digital Pressure Gauge for Keg
More info to come.
Goal: Monitor and adjust CO2 pressure on a keg, for carbonation and serving.
Corny keg gas quick-disconnect (1/4" male flare) -> 1/4" female flare nut -> short 1/4" aluminum tubing, flared -> 1/4" compression-to-FPT adapter -> 1/4" MPT w/ Schrader (tire) valve
The compression adapter was drilled on the drill press to accept the nozzle of a piezo pressure sensor from AllElectronics, which will be JB-Welded in place.
TBD. Will use AVR to read analog voltage/resistance from sensor. Segment display? Web-enable?
