Hi all,
I have tried to use Jim Koehler's spreadsheet to calculate the S/N, etc of a cylindrical toroid sensor but am not having much luck. If I increase "b", the length of the cylinder, it actually decreases the S/N. Is this correct? I thought increasing it from say 4" to 8" it would increase the S/N but seems to decrease it. In fact, my numbers seem to be low overall from what I would have expected. It may be that I'm using incorrect units causing some of my problems. I am trying to see what I could expect from using PVC pipes as forms but I just don't seem to be getting very good numbers. I got 8lbs of 20awg of wire delivered to my door a few minutes ago from Mouser and am ready to do something with it :-)
Thanks for any help,
Fred
