I have a project that requires measuring the thickness of an object at several locations and taking the average of those measurements.
You can get software that will take measurements from digital dial indicators, but it is limited, and for my application, digital dial indicators are too bulky and won’t fit together closely enough.
I am wondering if spring loaded linear potentiometers would work well as a stand in for dial indicators. I am not familiar with these devices and don’t know what kind of precision they have. I would most likely be using them with an arduino or something similar and would need about .002" or .003" resolution.
If anyone has any input or advice I’d really appreciate it!
