Brand: AIM Sports
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.
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. Sold individually.
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).
* Measures 0 - 50 psi pressure only; does not register vacuum. Not recommended as a manifold pressure sensor on normally-aspirated intake systems, which normally see air pressure below 0 psi.
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 dashes 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.
