AEM Gauge Components

AEM Gauge Components High-quality brass PSIa sensors engineered for accurate absolute pressure measurement in automotive and motorsport applications. Available in three ranges: 30 PSIa (2 BAR) , 50 PSIa (3.5 BAR) , and 75 PSIa (5 BAR) . Why choose AEM PSIa sensors? Absolute pressure sensing: PSIa is referenced to absolute zero, making it ideal for manifold pressure and vacuum measurements. Versatile ranges: Select from 30, 50, or 75 PSIa to match your engine tuning and boost monitoring needs. Durable construction: Brass housings provide corrosion resistance and long-term reliability in harsh environments. Recalibration capable: Sensors can be recalibrated to display zero at atmospheric pressure and negative values below atmosphere for vacuum readings. Common applications Engine manifold pressure (MAP) sensing Boost and vacuum monitoring Data logging and ECU integration Performance tuning and diagnostics At sea level a PSIa sensor reads approximately 14.7 PSI when exposed to atmospheric pressure. Choose AEM Gauge Components for precise, reliable absolute pressure readings that support better tuning, monitoring, and engine performance.
