AEM Electronics Stainless Steel Atmospheric Pressure (PSIg) Sensors provide highly accurate and rapid monitoring of pressure referenced against atmospheric pressure, available in a variety of working pressure ranges*. Ideal for applications requiring the feedback of crucial ECU information or calibration data.Stainless-steel sensors are 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 includedAEM's 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 applications such as oil pressure, fuel pressure, brake pressure, nitrous pressure etc. Stainless Steel sensors offer greater accuracy and faster response to pressure changes when compared to their equivalent brass body sensors, making them ideal fo
