AEM 150 PSIG Brass Sensor Kit – 1/8" NPT Male Thread

The AEM 150 PSIg Brass Pressure Sensor Kit is a dependable, cost-effective solution for monitoring fluid pressure in oil, fuel, brake, and nitrous systems. Designed for general-purpose use where absolute precision is not critical, this sensor provides accurate gauge pressure readings with simple analog output—ideal for gauges, logging, or piggyback ECU systems.

What is PSIg?
This sensor reads gauge pressure (PSIg), meaning it references pressure above atmospheric conditions. At sea level with no applied pressure, it will read 0 PSIg—making it suitable for closed fluid systems that don’t require vacuum data.

Brass vs Stainless – Choose Based on Your Needs

• Brass Sensor = Ruler – Use for reference readings, such as boost or fuel pressure gauges

• Stainless Sensor = Caliper – Use where ECU calibration or precise tuning is required

Key Features

• Pressure Range: 0–150 PSIg (gauge pressure)

• Sensor Type: Brass body with 1/8" NPT male thread

• Accuracy: ±3% of full scale

• Fluid Compatibility: Sealed housing, resistant to oil, fuel, brake fluid, and coolant
