Notes on pressure measurement
Selection guides and technical notes, written for engineers specifying a measurement system.

Choosing a flexible sensing film: range, array density and encapsulation
Three parameters constrain each other. Range headroom, array density and encapsulation are usually selected in the wrong order — here is the sequence that holds up in the field.
Technical
Is 20 Hz enough for blade pressure measurement?
A 20 Hz sampling rate rules out vibration and transient work — and that is exactly why it is the right choice for static and quasi-static load cases.

Bonding a sensing film to a blade surface: what actually fails
Most measurement errors on a blade do not come from the sensor — they come from the bond. Here are the three failure modes we see and how each shows up in the data.
