AEM Electronics PSIA Sensor Kits
AEM Electronics offers high-quality stainless steel PSIa sensor kits in 15
(1 BAR), 30 (2 BAR), 50 (3.5 BAR), 75 (5 BAR) and 100 (7 BAR). PSIa is
referenced to absolute zero—the pressure measurement when all the pressure
exerted by the atmosphere has been removed. The most common use for
absolute pressure sensors is reading manifold pressure. PSIa sensors are
required if you wish to measure vacuum. A PSIa sensor will read about 14.7
psi when the sensing element is exposed to atmospheric pressure at sea
level; however, they can be recalibrated to read zero at atmospheric, and a
negative number at values less than atmospheric pressure.
