Variable inductor

I have a variable inductor (a tranduscer, not a LVDT, because hasn´t excitation) and I need convert the output of transducer in postition of transducer. The frequency with the transducer measure the position of material is variable too.


The Analog has a AD698, but is this IC, the inductor has excitation, so the output is a variation of voltage, not a variable inductance.


Can you help me, with suggestions for my problem?


Thank you
