Product Overview
AEM 150 PSIg Brass Pressure Sensor Kit 30-2131-150
The AEM 30-2131-150 is a compact, brass-bodied pressure transducer that reads from 0 to 150 PSI above atmosphere (gauge pressure), so it shows zero with the port open to air. It screws straight into a 1/8″ NPT port and sends a linear 0.5–4.5 V signal to your gauge, dash or data logger, making it a straightforward way to keep an eye on oil pressure, fuel pressure, brake line pressure or nitrous bottle pressure.
Why choose this sensor
- Linear 0.5–4.5 V output that is simple to scale in most dashes, loggers and gauges
- Stainless steel wetted parts (304L/316L) inside a durable brass housing
- Integral weatherproof connector with mating plug, pins and pin lock supplied
- Fast response time of under 1 ms
- Rated from -40°C to 105°C with a 300 PSI burst pressure
Key specifications
Range is 0–150 PSIg with an accuracy of ±3% of full scale across the operating temperature range, including linearity, hysteresis and repeatability. The thread is 1/8″ NPT male and the whole unit weighs under 85 g. It is vibration rated to 20 g from 100 to 2000 Hz on all three axes.
Choosing the right sensor
Brass sensors such as this are intended for monitoring and display. For pressure inputs that an ECU uses for fuelling or ignition calibration, AEM recommends its stainless steel sensor range instead. Because this is a gauge-type sensor it is not suited to reading boost as absolute manifold pressure for an ECU.
Fitting advice
Use a suitable thread sealant on the NPT thread and avoid overtightening the brass body. On engines where the sender port vibrates heavily, a remote mount on a braided line and bracket will help sensor life. Wiring needs a 5 V reference, sensor ground and signal input on your gauge or logger; extension wiring is not included.
