Popis: A transducer of ultra-thin conductor parameters on the basis of a superhigh-frequency open-loop resonator is considered. The conditions for attaining the maximum sensitivity of such a transducer were found by analyzing the spectral characteristics of a resonator with a conductor. A scheme for creating these conditions in a device for the noncontact nondestructive radio-wave resonance diagnostics of the parameters of a glass-coated cast microwire that was manufactured using the Ulitovsky-Taylor technology was proposed. The results of testing the working device model for long-term stability and the ability to detect small local inhomogeneities and slow microwire parameter drifts are given. The device was shown to have much better characteristics in comparison with the known devices.
