Best pressure measurement

dries

I wondered how you can measure (static) pressure, with an as high as possible accuracy. Could you share your experience about which sensor and setup you allready used?

I would like to measure the static pressure before and after a fan with an accuracy of 10[Pa]. Do you think this is possible?

Do you mean 1 part in 10,000 of atmospheric pressure? Why the precision?

If you are trying to measure the DP across the fan you might manage it with an inclined manometer.

Yes I mean 1/10000 of atmospheric pressure, the accuracy is needed to determine the flow from a fan curve.

I can't imagine why you need that much precision for a fan curve, but a mid-level digital manometer can do it: http://www.google.com/products/catal...ed=0CGAQ8wIwAA
