This "absolute pressure" sensor is ideal for measuring vapor (gas) pressures, from intake boost to crankcase pressure. The 50 psi pressure range is based on perfect vacuum (i.e., from 15 psi below atmospheric pressure to 35 psi above). This sensor is marked "0-50psiA" to differentiate it from the standard 0-50 psi sensor (marked "0-50psiSG"), which does not measure vacuum.
KA pressure sensors are more robust than the old VDO-style pressure sensors, but all sensors should still be isolated from engine heat and vibration whenever possible. It is compatible with all AiM MX-Series dashes, EVO3/EVO4/EVO5 loggers, CAN Channel Expansion Hub, and the MyChron Expansion. 1/8 NPT male threads. Body design may vary from photo.
This sensor has a 50cm (19.68") long cable with a 719 (four-pin plastic push-on type) connector permanently attached. Use a My Chron 719-719 Patch Cable (Part No. MC-211) to connect to any AiM MX-Series dash or EVO3/EVO5 logger. EVO4/EVO4S, CAN Channel Expansion Hub, and MyChron Expansion require a 712-719 Patch Cable (Part No. MC-210, sold separately).
Note: This sensor requires a "+Vb" (battery voltage) power supply, not the traditional "Vref" (5V reference signal) used by older sensors. Current MX-Series dashes, EVO4 and later loggers, MyChron Expansion, and CAN Channel Expansion Hubs have the +Vb supply available on all analog channels. MyChron3 and older do not have the necessary +Vb supply on any channel. MXL Pista and EVO3 Pista only have +Vb on Channels 4 through 8. MXL Pro and EVO3 Pro only have +Vb on Channels 8 through 11.
