AiM Fluid/Air Pressure Sensor, 0-50 psi, 1/8 NPT (used)

This 0-50 psi sensor is suitable for measuring coolant pressure, fuel pressure, or boost pressure.* It measures pressure only, relative to standardized atmospheric (also called "sealed gauge pressure", 0 psi on this sensor equals atmospheric pressure). This version is marked "0-50psiSG" to differentiate it from the "absolute pressure" sensor (marked "0-50psiA"), which can measure vacuum.
