This AEM Electronics Brass Atmospheric Pressure Sensor Kit is designed for automotive enthusiasts and tuners seeking accurate and reliable monitoring of pressure referenced against atmospheric pressure. Its key benefit is providing stable, consistent feedback ideal for gauges like boost or manifold pressure, though its slower response time makes it less suited for rapidly fluctuating ECU data feeds. The kit includes a 150 PSIg rated brass sensor, connector, pins, and pin lock.

This specific kit is rated for a maximum of 150 PSIg (Pounds per Square Inch Gauge).
PSIg stands for Pounds per Square Inch Gauge. It measures pressure relative to the surrounding atmospheric pressure. When exposed to atmospheric pressure, a gauge sensor will read 0 PSIg.
While accurate, the brass sensor's smoother feedback is less ideal for rapidly fluctuating ECU data compared to stainless steel sensors. It's better suited for gauge feeds or applications requiring stable pressure references.
The wetted materials are 304L and 316L Stainless Steel. The sensor body itself is brass.
Yes, the kit includes the 150 PSIg rated Brass Sensor, a weatherproof connector, pins, and a pin lock.
The sensor is accurate to within +/- 3% of full scale, which includes repeatability, hysteresis, and linearity.
The sensor can operate reliably in temperatures ranging from -40°C to 105°C (-40°F to 221°F).
Verify the sensor is measuring gauge pressure (referenced to atmosphere). Ensure the port is not blocked and the sensor is properly threaded. Check electrical connections for continuity.
Confirm the sensor is compatible with the application's pressure range. Check for air leaks in the line between the pressure source and the sensor. Ensure electrical connections are secure and free from corrosion. Verify the output signal is correctly interpreted by the gauge or ECU.
Check the electrical connections to the sensor, ensuring power and ground are correctly supplied according to the 0.5-4.5Vdc output specification. Inspect the wiring harness for damage.
Setup: The sensor features a standard 1/8" NPT male thread for direct installation into appropriate ports. Ensure the port is clean before threading the sensor in. Connect the included weatherproof connector, pins, and pin lock to the sensor and corresponding wiring harness. Refer to the sensor's output specification (0.5 to 4.5Vdc Linear) for proper wiring into your monitoring system or gauge.
Compatibility: This sensor is compatible with any automotive application requiring atmospheric pressure monitoring up to 150 PSIg. It is suitable for use with oil pressure, fuel pressure, brake pressure, nitrous pressure, and boost/manifold pressure applications.
Care: The sensor's sealed housing is designed to be impervious to most automotive fluids. However, avoid prolonged exposure to harsh solvents or extreme chemicals not typically found in engine bays. Cleaning the sensor body can be done with a soft, damp cloth. Ensure electrical connections are clean and dry.
