Designing Coil of Eddy Current Sensor - Get Tips & Solutions

[naibes]

I have some problems designing the coil of an eddy current sensor.
I've been searching for some information in different pages and each of it has some criterion for the desing.
I would like to know if anyone knows which criterion must I follow to achieve a successful desing.

for any sugestion please email me at naibes@yahoo.es

where do you want to measure eddy currents?

 

[naibes]

I want to measure the voltage variations that occur because of the movement of a non-magnetic target near a pot-core coil.

where? Let's say on a extreme operating conditions
