A few days ago Jeff handed us each a sensor off of a piece of equipment, and i happened to get a differential pressure sensor with a high and low side.
i was able to hook up the leads. power ground and a signal lead. hooking my multi meter inline with the signal wire and ground. i was able to get a base reading of around .25 of a volt for ambient air pressure.
Blowing into the highside i was able to get it up to 4.1 volts out of the 5 volt system i was hooked into. and droped down to .015 of a volt on the low side.
That was fun, eh? This was the first on of this style I have seen work.
ReplyDeleteit was pretty cool and fun, and learning the the differential pressure difference between the front of the catalytic converter or DPF was interesting to learn about
