I need a differential pressure sensor. Two to really do it right.
This one is perfect: MPXV7002DP Transducer APM2.5 APM2.52 Differential Pressure Sensor
But, it won't get here for quite some time.
It occured to me that the automotive industry uses them. Specifically I know they are used for EGR systems. They may be used elsewhere as well.
If I had a part number, I could go down to the auto parts store and pick one up today.
I have other stuff to work on. Anyone want to see if they can find a suitable sensor?
