Hi
In our application we need to determine the best coil design in our setup with given parameters.
We have 4 coil designs, and we want to measure changes in distance between the coil and a metal target with the highest precision, but if we could go with a small metal target that would be benefitial due to space limitations.
We have made 4 four stainless steel disks of different diameters to be tested with the 4 coils. They are 15mm, 20mm, 30mm and 40mm. The coils are in the range 35 to 40mm i diameter.
Are there any guidelines which explains how I go about to determine test criterias and endpoints in my testing?
In the case where all coils react to all metal disks what do I do check wether one disk/coil configuration provides better resolution, linearity or range than another configuration?
If anyone has any experience or insight to help me it would be greatly appreciated!
