Hello, I think the weapon of your choice would be a so called 'micrometer' http://en.wikipedia.org/wiki/Micrometer
Lets try to design the sensor you need,design 1: - conductive wire-----------------------------------imagine a V shaped sensor that guides the wire.depending on the thickness of the wire it will be higher or lower in the V shapemake the sides of the V of a conducting material with known (relative to wire high) resistanceThe place of the wire will change the resistance of the V as the level where the wire is short-cuts the current.
The place of the wire will change the resistance of the V as the level where the wire is short-cuts the current.
Coils that I have wound very carefully by hand agree almost perfectly, whereas sloppily wound coils deviate significantly.
Would it not be sufficient to machine-wind one layer of the coil, manually pause it at the end of the layer and note the number of turns, and then program the winder to use the same number of turns for the other layers?
This is a nice diagram explaining the difference between accuracy and precision
