Product details
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. 150 PSIg Brass Sensor Kit, Brass Sensor Body, 1/8-inch NPT Male Thread, Includes 150 PSIg Brass Sensor, Connector and Pins AEM 150 PSIg Brass Sensor Kit. Brass Sensor Body. 1/8" NPT Male Thread. Includes: 150 PSIg Brass Sensor, Connector & Pins 150 PSIg Brass Sensor Kit. Brass Sensor Body. 1/8 in NPT Male Thread. Includes: 150 PSIg Brass Sensor, Connector & Pins 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. Stainless Steel Pressure Sensor = Caliper Brass Gauge style (PSIg) Pressure Sensors Which Pressure Sensor is right for you? AEM 150 PSIg Brass Sensor Kit Brass Pressure Sensor = Ruler 1/8 in.
