WebAug 12, 2010 · By Fondriest Staff on August 12, 2010. Barometric pressure is the weight of the overlying air pressing down on the earth. It is also known as air pressure. Low barometric pressure means the overlying air is rising, whereas high pressure means the overlying air is sinking. WebVacuum pressure is measured relative to ambient atmospheric pressure. It is referred to as pounds per square inch (vacuum) or PSIV. The electrical output of a vacuum pressure transducer is 0 VDC at 0 PSIV (14.7 PSIA) and full scale output (typically 5 VDC) at full scale vacuum, 14.7 (0 PSIA). The vacuum pressure transducer gives an increased ...
