AEM 100 PSIG Brass Sensor Kit – 1/8" NPT Male Thread

The AEM 100 PSIg Brass Pressure Sensor Kit is a cost-effective solution for monitoring pressure in fuel, oil, brake, or nitrous systems where ECU calibration is not critical. With a 1/8" NPT male thread and analog output scaled for easy data reference, this sensor is ideal for gauge integration, general logging, and performance applications requiring reliable pressure feedback.

Gauge Pressure Simplified
This is a PSIg sensor, meaning it measures gauge pressure, or pressure relative to atmospheric conditions. When exposed to ambient air at sea level, the sensor reads 0 PSIg—making it perfect for systems that do not require vacuum measurement, such as fuel and brake circuits.
