MAP & Pressure Sensors

Stainless Steel Absolute (PSIa) Pressure Sensors:
AEM offers high quality stainless steel PSIa sensors in 15psi, 30psi, 50psi, 75psi, and 100psi. PSIa is referenced to absolute zero. Absolute zero is the pressure measurement when all the pressure exerted by the atmosphere has been removed.
The most common use for absolute pressure sensors is reading manifold pressure. PSIa pressure sensors are required if you wish to measure vacuum. A PSIa sensor will read about 14.7 PSI when the sensing element is exposed to atmospheric pressure at sea level however they can be recalibrated to read zero at atmospheric and a negative number at values less than atmospheric pressure.

Stainless Steel Gauge style (PSIg) Pressure Sensors:
AEM offers high quality stainless steel PSIg sensors in 100psi, 150psi, 500psi, 1,000psi, and 2,000psi.  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.

Brass Absolute (PSIa) Pressure Sensors:
AEM offer high quality brass PSIa sensors in 30psi, 50psi, and 75psi. PSIa is referenced to absolute zero. Absolute zero is the pressure measurement when all the pressure exerted by the atmosphere has been removed. The most common use for absolute pressure sensors is reading manifold pressure. PSIa sensors are required of you wish to measure vacuum. A PSIa sensor will read about 14.7 PSI when the sensing element is exposed to atmospheric pressure at sea level however they can be recalibrated to read zero at atmospheric and a negative number at values less than atmospheric pressure.

Brass Gauge style (PSIg) Pressure Sensors
AEM offers brass PSIg sensors in 15psi, 100psi, and 150psi. 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.
 
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:
 
Stainless Pressure Sensor = Caliper
Use a SS Pressure Sensor where you need exact details of the pressure.
  • Stainless-steel 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
Example: MAP Sensor information for the ECU – Calibration/crucial information for the ECU.
  
Brass Pressure Sensor = Ruler
Use a Brass Pressure Sensor where you need a good reference to what pressure is being seen.
  • Brass sensors accurate to within 3% 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
Example: Brass Pressure Sensor used for a Boost Gauge – Reference/Information for knowing manifold pressure, not for ECU calibration.
