Description This is a high quality 3.5bar map sensor (0 to 50psi absolute) ideal for engines running in excess of 2 bars of boost pressure but that do not desire the reduced map resolution that a 4 bar sensor might offer. The sensor has a 1/8 NPT male thread fitting but is supplied with a 4mm barb tail should you wish to connect it straight to a hose. It comes with the detatchable 3-wire harness shown in the picture. The sensor is made in the USA to military standards. This is a high quality sensor. Specifications: Supply voltage = 5vdc 0psi (absolute) output = 0.5v 50psi (absolute) output = 4.5v Wiring: Red = 5vdc (from ECU) Black = 0v (ground) Green = signal output <!– Click here to view the data sheet –!>
