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

High-quality sealed sensor housings are virtually impervious to automotive fluids (360-degree welded wetted area)
Use a Brass Pressure Gauge Sensor where you need a good reference to what pressure is being seen.
Example: MAP Sensor information for the ECU - Calibration/crucial information for the ECU.
Use a SS Pressure Sensor where you need exact details of the pressure.
