AEM brass PSIa sensors are offered in three configurations—30(2BAR), 50 (3.5BAR), and 75 (5BAR)—designed for accurate manifold pressure measurement. PSIa refers to absolute zero, the pressure value when atmospheric pressure is removed, and is commonly used for reading manifold pressure or vacuum. A PSIa sensor reads approximately 14.7 PSI at sea level when exposed to atmospheric pressure and can be recalibrated to read zero at atmospheric pressure or a negative reading below atmospheric pressure. This sensor kit features a brass body with high-quality sealing to resist fluids and includes a weather-resistant connector and pins for reliable signal integrity.
