AEM 150 PSIg Brass Sensor Kit: 1/8″ NPT Sensor, Connector & Pins

AEM 150 PSIg Brass Sensor Kit. Brass Sensor Body. 1/8″ NPT Male Thread. Includes: 150 PSIg Brass Sensor, Connector & Pins


  • Description: AEM 150 PSIg Brass Sensor Kit
  • Part Number: AEM30-2131-150
  • Supplier: AEM Performance Electronic


  • Brass sensors accurate to within 1% of full scale (pressure sensors)
  • High-quality sealed sensor housings are virtually impervious to automotive fluids (360-degree welded wetted area)
  • Connector and pins included

AEM offers brass PSIg sensors in 15, 100 and 150. Gauge style pressure sensors reference pressure above atmospheric pressure. When exposed to atmospheric pressure, gauge style pressure sensors will read 0 psig. Gauge style pressure sensors are commonly used for oil pressure, fuel pressure, brake pressure, nitrous pressure etc.

These pressure sensors are made of brass and offer accurate readings within 3% of their maximum measurable pressure (full scale). They are built tough with high-quality sealed housings that can withstand exposure to automotive fluids thanks to a 360-degree welded construction. The sensor comes complete with a connector and pins for easy installation.

The accuracy is guaranteed from -40 degrees Celsius to 105 degrees Celsius (or -40 degrees Fahrenheit to 221 degrees Fahrenheit) and takes into account repeatability, hysteresis, and linearity. The sensor can handle operating temperatures within this range as well. In terms of pressure tolerance, it has a burst pressure rating of 300 PSI and boasts a very fast response time of less than 1 millisecond. It’s also built to handle vibration across a range of frequencies (100 to 2000Hz) and forces (20g).

Some additional details include a 1/8″ NPT male thread for connection, a lightweight design (under 85 grams), and a linear voltage output between 0.5 and 4.5 volts DC. The electrical termination features an integral weatherproof connector with a mating connector, pins, and a pin lock for secure connection. Finally, the package includes the 150 PSI gauge pressure (psig) brass sensor itself, the connector, pins, and the pin lock.

Which Pressure Sensor is right for you?

There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool. For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper should be used. The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if we think about it in these terms:

Brass Pressure Sensor = Ruler

Use a Brass Pressure Sensor where you need a good reference to what pressure is being seen.

For example: Brass Pressure Sensor used for a Boost Gauge – Reference/Information for knowing manifold pressure, not for ECU calibration.

Stainless Pressure Sensor = Caliper

Use a SS Pressure Sensor where you need exact details of the pressure.

For example: MAP Sensor information for the ECU – Calibration/crucial information for the ECU.
