摘要：
The experimental optimizaton of the coil for an eddy-current displacement transducer probe is presented in the paper. The coil geometry is optimized for the special design of the transducer as a meter of the real part of the probe's impedance. Measurement of the transducer's transfer function has been performed with several samples of ring-shaped coils, as well as with the flat, pancake-shaped coil and with the single-layered cylindrical coil. For the sake of comparison, measurement with the ferrite-cored coil has been included too. The measurement results clearly indicate that the optimal coil geometry is a ring with a uniform and very small cross section of the winding.
