Gauge style (PSIg) Pressure Sensors
AEM offers high quality PSIg sensors in 100, 150, 500, 1,000,
and 2,000. 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:
Brass Pressure Sensor = Ruler
Use a Brass Pressure Sensor where you need a good reference to what
pressure is being seen.
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.
Example: MAP Sensor information for the ECU – Calibration/crucial information for the ECU.
