What does PSI mean on a pressure sensor?
PSIG -PSI Gauge. Gauge pressure is measured relative to ambient atmospheric pressure. A vessel completely void of any air molecules (at sea level) would be roughly -14.7 PSIG, and ambient air pressure is always measured as 0 PSIG, regardless of whatever current barometric pressure is. For this reason, barometric pressure sensors are absolute;
